3.0 GENERAL DESCRIPTION  
Seagate® Enterprise Performance 10K HDD v7 drives provide high performance, high capacity data storage for a variety of  
systems including engineering workstations, network servers, mainframes, and supercomputers. The Serial Attached SCSI  
interface is designed to meet next-generation computing demands for performance, scalability, flexibility and high-density  
storage requirements.  
Seagate Enterprise Performance 10K HDD drives are random access storage devices designed to support the Serial  
Attached SCSI Protocol as described in the ANSI specifications, this document, and the SAS Interface Manual (part number  
100293071) which describes the general interface characteristics of this drive. Seagate Enterprise Performance 10K HDD  
drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1  
standard. The SAS connectors, cables and electrical interface are compatible with Serial ATA (SATA), giving future users the  
choice of populating their systems with either SAS or SATA hard disk drives. This allows integrators to continue to leverage  
existing investment in SCSI while gaining a 6Gb/s serial data transfer rate.  
Note. Never disassemble the HDA and do not attempt to service items in the sealed enclosure (heads, media, actuator,  
etc.) as this requires special facilities. The drive does not contain user-replaceable parts. Opening the HDA for  
any reason voids the warranty.  
Seagate Enterprise Performance 10K HDD drives use a dedicated load/unload zone at the outermost radius of the media to  
eliminate the possibility of destroying or degrading data by landing in the data zone. The heads automatically go to the ramp  
load/unload when power is removed from the drive.  
An automatic shipping lock prevents potential damage to the heads and discs that results from movement during shipping  
and handling. The shipping lock disengages and the head load process begins when power is applied to the drive.  
The drives also use a high-performance actuator assembly with a low-inertia, balanced, patented, straight arm design that  
provides excellent performance with minimal power dissipation.

FORMATTED CAPACITIES  
Standard OEM models are formatted to 512 bytes per block. The block size is selectable at format time. Supported block  
sizes are 512, 520, 524, and 528. Users having the necessary equipment may modify the data block size before issuing a  
format command and obtain different formatted capacities than those listed.  
To provide a stable target capacity environment and at the same time provide users with flexibility if they choose, Seagate  
recommends product planning in one of two modes:  
Seagate designs specify capacity points at certain block sizes that Seagate guarantees current and future products will  
meet. We recommend customers use this capacity in their project planning, as it ensures a stable operating point with  
backward and forward compatibility from generation to generation. The current guaranteed operating points for this product  
are shown below.

PROGRAMMABLE DRIVE CAPACITY  
Using the Mode Select command, the drive can change its capacity to something less than maximum. See the Mode Select  
(6) parameter list table in the SAS Interface Manual, part number 100293071. A value of zero in the Number of Blocks field  
indicates that the drive will not change the capacity it is currently formatted to have. A number other than zero and less than  
the maximum number of LBAs in the Number of Blocks field changes the total drive capacity to the value in the Number of  
Blocks field. A value greater than the maximum number of LBAs is rounded down to the maximum capacity.

FACTORY-INSTALLED OPTIONS  
The following items may be ordered which are incorporated at the manufacturing facility during production or packaged  
before shipping. Some of the options available are (not an exhaustive list of possible options):  
• Other capacities can be ordered depending on sparing scheme and sector size requested.  
• Single-unit shipping pack. The drive is normally shipped in bulk packaging to provide maximum protection against transit  
damage. Units shipped individually require additional protection as provided by the single unit shipping pack. Users plan-  
ning single unit distribution should specify this option.  
• The Safety and Regulatory Agency Specifications, part number 75789512, is usually included with each standard OEM  
drive shipped, but extra copies may be ordered.

4.3  
START/STOP TIME  
The drive accepts the commands listed in the SAS Interface Manual less than 3 seconds after DC power has been applied.  
If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a START STOP UNIT  
command with the START bit equal to 0, the drive becomes ready for normal operations within 20 seconds (excluding the  
error recovery procedure).  
If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY (ENABLE  
SPINUP) primitive, the drive waits for a START STOP UNIT command with the START bit equal to 1. After receiving a  
START STOP UNIT command with the START bit equal to 1, the drive waits for a NOTIFY (ENABLE SPINUP) primitive.  
After receiving a NOTIFY (ENABLE SPINUP) primitive through either port, the drive becomes ready for normal operations  
within 20 seconds (excluding the error recovery procedure).  
If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does not receive a  
NOTIFY (ENABLE SPINUP) primitive within 5 seconds, the drive fails the START STOP UNIT command.  
The START STOP UNIT command may be used to command the drive to stop the spindle. Stop time is 20 seconds  
(maximum) from removal of DC power. SCSI stop time is 20 seconds. There is no power control switch on the drive.  
4.4  
PREFETCH/MULTI-SEGMENTED CACHE CONTROL  
The drive provides a prefetch (read look-ahead) and multi-segmented cache control algorithms that in many cases can  
enhance system performance. Cache refers to the drive buffer storage space when it is used in cache operations. To select  
this feature, the host sends the Mode Select command with the proper values in the applicable bytes in page 08h. Prefetch  
and cache operations are independent features from the standpoint that each is enabled and disabled independently using  
the Mode Select command; however, in actual operation, the prefetch feature overlaps cache operation somewhat as  
All default cache and prefetch mode parameter values (Mode Page 08h) for standard OEM versions of this drive family are  
4.5  
CACHE OPERATION  
Note. Refer to the SAS Interface Manual for more detail concerning the cache bits.  
Of the 64MB physical buffer space in the drive, approximately 30,000KB are available as a data cache. The remaining buffer  
space is reserved for internal drive use.  
The drive keeps track of the logical block addresses of the data stored in each segment of the buffer. If the cache is enabled  
(see RCD bit in the SAS Interface Manual), data requested by the host with a read command is retrieved from the buffer, if  
possible, before any disk access is initiated. If cache operation is not enabled, the buffer is still used, but only as circular  
buffer segments during disk medium read operations (disregarding Prefetch operation for the moment). That is, the drive  
does not check in the buffer segments for the requested read data, but goes directly to the medium to retrieve it. The  
retrieved data merely passes through some buffer segment on the way to the host. All data transfers to the host are in  
accordance with buffer-full ratio rules. See the explanation provided with the information about Mode Page 02h (disconnect/  
reconnect control) in the SAS Interface Manual.  
The following is a simplified description of the prefetch/cache operation:  
Case A—read command is received and all of the requested logical blocks are already in the cache:  
1. Drive transfers the requested logical blocks to the initiator.  
Case B—A Read command requests data, and at least one requested logical block is not in any segment of the cache:  
1. The drive fetches the requested logical blocks from the disk and transfers them into a segment, and then from there to  
the host in accordance with the Mode Select Disconnect/Reconnect parameters, page 02h.  
2. If the prefetch feature is enabled, refer to section 4.5.2 for operation from this point.

Each cache segment is actually a self-contained circular buffer whose length is an integer number of logical blocks. The  
drive dynamically creates and removes segments based on the workload. The wrap-around capability of the individual  
segments greatly enhances the cache’s overall performance.  
Note. The size of each segment is not reported by Mode Sense command page 08h, bytes 14 and 15. The value  
0XFFFF is always reported regardless of the actual size of the segment. Sending a size specification using the  
Mode Select command (bytes 14 and 15) does not set up a new segment size. If the STRICT bit in Mode page  
00h (byte 2, bit 1) is set to one, the drive responds as it does for any attempt to change an unchangeable param-  
eter.  
4.5.1 Caching write data  
Write caching is a write operation by the drive that makes use of a drive buffer storage area where the data to be written to  
the medium is stored while the drive performs the Write command.  
If read caching is enabled (RCD=0), then data written to the medium is retained in the cache to be made available for future  
read cache hits. The same buffer space and segmentation is used as set up for read functions. The buffer segmentation  
scheme is set up or changed independently, having nothing to do with the state of RCD. When a write command is issued, if  
RCD=0, the cache is first checked to see if any logical blocks that are to be written are already stored in the cache from a  
previous read or write command. If there are, the respective cache segments are cleared. The new data is cached for  
subsequent Read commands.  
If the number of write data logical blocks exceed the size of the segment being written into, when the end of the segment is  
reached, the data is written into the beginning of the same cache segment, overwriting the data that was written there at the  
beginning of the operation; however, the drive does not overwrite data that has not yet been written to the medium.  
If write caching is enabled (WCE=1), then the drive may return Good status on a write command after the data has been  
transferred into the cache, but before the data has been written to the medium. If an error occurs while writing the data to the  
medium, and Good status has already been returned, a deferred error will be generated.  
The Synchronize Cache command may be used to force the drive to write all cached write data to the medium. Upon  
completion of a Synchronize Cache command, all data received from previous write commands will have been written to the  
4.5.2 Prefetch operation  
If the Prefetch feature is enabled, data in contiguous logical blocks on the disk immediately beyond that which was requested  
by a Read command are retrieved and stored in the buffer for immediate transfer from the buffer to the host on subsequent  
Read commands that request those logical blocks (this is true even if cache operation is disabled). Though the prefetch  
operation uses the buffer as a cache, finding the requested data in the buffer is a prefetch hit, not a cache operation hit.  
To enable Prefetch, use Mode Select page 08h, byte 12, bit 5 (Disable Read Ahead - DRA bit). DRA bit = 0 enables prefetch.  
The drive does not use the Max Prefetch field (bytes 8 and 9) or the Prefetch Ceiling field (bytes 10 and 11).  
When prefetch (read look-ahead) is enabled (enabled by DRA = 0), the drive enables prefetch of contiguous blocks from the  
disk when it senses that a prefetch hit will likely occur. The drive disables prefetch when it decides that a prefetch hit is not  
likely to occur.

5.1  
ERROR RATES  
The error rates stated in this manual assume the following:  
• The drive is operated in accordance with this manual using DC power as defined in paragraph 6.3, "DC power require-  
• Errors caused by host system failures are excluded from error rate computations.  
• Assume random data.  
• Default OEM error recovery settings are applied. This includes AWRE, ARRE, full read retries, full write retries and full retry  
time.  
5.1.1 Recoverable Errors  
Recoverable errors are those detected and corrected by the drive, and do not require user intervention.  
Recoverable Data errors will use Error Correction when needed.  
Recovered Data error rate is determined using read bits transferred for recoverable errors occurring during a read, and using  
write bits transferred for recoverable errors occurring during a write.  
5.1.2 Unrecoverable Errors  
An unrecoverable data error is defined as a failure of the drive to recover data from the media. These errors occur due to  
head/media or write problems. Unrecoverable data errors are only detected during read operations, but not caused by the  
read. If an unrecoverable data error is detected, a MEDIUM ERROR (03h) in the Sense Key will be reported. Multiple  
unrecoverable data errors resulting from the same cause are treated as 1 error.  
5.1.3 Seek errors  
A seek error is defined as a failure of the drive to position the heads to the addressed track. After detecting an initial seek  
error, the drive automatically performs an error recovery process. If the error recovery process fails, a seek positioning error  
(Error code = 15h or 02h) will be reported with a Hardware error (04h) in the Sense Key. Recoverable seek errors are  
8
specified at Less than 10 errors in 10 seeks. Unrecoverable seek errors (Sense Key = 04h) are classified as drive failures.  
5.1.4 Interface errors  
An interface error is defined as a failure of the receiver on a port to recover the data as transmitted by the device port  
connected to the receiver. The error may be detected as a running disparity error, illegal code, loss of word sync, or CRC  
error.

5.2  
RELIABILITY AND SERVICE  
The reliability of Seagate Enterprise Performance 10K HDD disk drives can be enhance by ensuring that the drive receives  
5.2.1 Annualized Failure Rate (AFR) and Mean Time Between Failure (MTBF)  
The production disk drive shall achieve an AFR of 0.44% (MTBF of 2,000,000 hours) when operated in an environment that  
ensures the HDA case temperatures do not exceed the values specified in Section 6.5. Operation at case temperatures  
outside the specifications in Section 6.5 may increase the product AFR (decrease the MTBF). The AFR (MTBF) is a  
population statistic not relevant to individual units.  
The AFR (MTBF) specification is based on the following assumptions for Enterprise Storage System environments:  
• 8760 power-on hours per year.  
• 250 average on/off cycles per year.  
• Operations at nominal voltages.  
• Systems will provide adequate cooling to ensure the case temperatures specified in Section 6.5 are not exceeded. Tem-  
peratures outside the specifications in Section 6.5 will increase the product AFR and decrease the MTBF.  
5.2.2 Preventive maintenance  
No routine scheduled preventive maintenance is required.  
5.2.3 Hot plugging the drive  
When a disk is powered on by switching the power or hot plugged, the drive runs a self test before attempting to  
communicate on its’ interfaces. When the self test completes successfully, the drive initiates a Link Reset starting with OOB.  
An attached device should respond to the link reset. If the link reset attempt fails, or any time the drive looses sync, the drive  
initiated link reset. The drive will initiate link reset once per second but alternates between port A and B. Therefore each port  
will attempt a link reset once per 2 seconds assuming both ports are out of sync.  
If the self-test fails, the drive does not respond to link reset on the failing port.  
Note. It is the responsibility of the systems integrator to assure that no temperature, energy, voltage hazard, or ESD  
potential hazard is presented during the hot connect/disconnect operation. Discharge the static electricity from  
the drive carrier prior to inserting it into the system.  
Caution. The drive motor must come to a complete stop prior to changing the plane of operation. This time is required to  
insure data integrity.  
5.2.4 S.M.A.R.T.  
S.M.A.R.T. is an acronym for Self-Monitoring Analysis and Reporting Technology. This technology is intended to recognize  
conditions that indicate imminent drive failure and is designed to provide sufficient warning of a failure to allow an application  
to back up the data before an actual failure occurs.  
Note. The drive’s firmware monitors specific attributes for degradation over time but can’t predict instantaneous drive  
failures.  
Each monitored attribute has been selected to monitor a specific set of failure conditions in the operating performance of the  
drive and the thresholds are optimized to minimize “false” and “failed” predictions.  
Controlling S.M.A.R.T.  
The operating mode of S.M.A.R.T. is controlled by the DEXCPT and PERF bits on the Informational Exceptions Control  
mode page (1Ch). Use the DEXCPT bit to enable or disable the S.M.A.R.T. feature. Setting the DEXCPT bit disables all  
S.M.A.R.T. functions. When enabled, S.M.A.R.T. collects on-line data as the drive performs normal read and write  
operations. When the PERF bit is set, the drive is considered to be in “On-line Mode Only” and will not perform off-line  
functions.

Applications can measure off-line attributes and force the drive to save the data by using the Rezero Unit command. Forcing  
S.M.A.R.T. resets the timer so that the next scheduled interrupt is in one hour.  
Applications can interrogate the drive through the host to determine the time remaining before the next scheduled  
measurement and data logging process occurs. To accomplish this, issue a Log Sense command to log page 0x3E. This  
allows applications to control when S.M.A.R.T. interruptions occur. Forcing S.M.A.R.T. with the RTZ command resets the  
timer.  
Performance impact  
S.M.A.R.T. attribute data is saved to the disk so that the events that caused a predictive failure can be recreated. The drive  
measures and saves parameters once every hour subject to an idle period on the drive interfaces. The process of measuring  
off-line attribute data and saving data to the disk is interruptable. The maximum on-line only processing delay is summarized  
below  
Maximum processing delay  
Fully-enabled delay  
DEXCPT = 0  
S.M.A.R.T. delay times  
75 ms  
Reporting control  
Reporting is controlled by the MRIE bits in the Informational Exceptions Control mode page (1Ch). Subject to the reporting  
method. For example, if the MRIE is set to one, the firmware will issue to the host an 01-5D00 sense code. The FRU field  
contains the type of predictive failure that occurred. The error code is preserved through bus resets and power cycles.  
Determining rate  
S.M.A.R.T. monitors the rate at which errors occur and signals a predictive failure if the rate of degraded errors increases to  
an unacceptable level. To determine rate, error events are logged and compared to the number of total operations for a given  
attribute. The interval defines the number of operations over which to measure the rate. The counter that keeps track of the  
current number of operations is referred to as the Interval Counter.  
S.M.A.R.T. measures error rates. All errors for each monitored attribute are recorded. A counter keeps track of the number of  
errors for the current interval. This counter is referred to as the Failure Counter.  
Error rate is the number of errors per operation. The algorithm that S.M.A.R.T. uses to record rates of error is to set  
thresholds for the number of errors and their interval. If the number of errors exceeds the threshold before the interval  
expires, the error rate is considered to be unacceptable. If the number of errors does not exceed the threshold before the  
interval expires, the error rate is considered to be acceptable. In either case, the interval and failure counters are reset and  
the process starts over.  
Predictive failures  
S.M.A.R.T. signals predictive failures when the drive is performing unacceptably for a period of time. The firmware keeps a  
running count of the number of times the error rate for each attribute is unacceptable. To accomplish this, a counter is  
incremented each time the error rate is unacceptable and decremented (not to exceed zero) whenever the error rate is  
acceptable. If the counter continually increments such that it reaches the predictive threshold, a predictive failure is signaled.  
This counter is referred to as the Failure History Counter. There is a separate Failure History Counter for each attribute.

5.2.5 Thermal monitor  
Seagate Enterprise Performance 10K HDD drives implement a temperature warning system which:  
1. Signals the host if the temperature exceeds a value which would threaten the drive.  
2. Saves a S.M.A.R.T. data frame on the drive which exceeds the threatening temperature value.  
A temperature sensor monitors the drive temperature and issues a warning over the interface when the temperature  
exceeds a set threshold. The temperature is measured at power-up and then at ten-minute intervals after power-up.  
The thermal monitor system generates a warning code of 01-0B01 when the temperature exceeds the specified limit in  
compliance with the SCSI standard.  
This feature is controlled by the Enable Warning (EWasc) bit, and the reporting mechanism is controlled by the Method of  
Reporting Informational Exceptions field (MRIE) on the Informational Exceptions Control (IEC) mode page (1Ch).  
5.2.6 Drive Self Test (DST)  
Drive Self Test (DST) is a technology designed to recognize drive fault conditions that qualify the drive as a failed unit. DST  
validates the functionality of the drive at a system level.  
There are two test coverage options implemented in DST:  
1. Extended test  
2. Short test  
The most thorough option is the extended test that performs various tests on the drive and scans every logical block address  
(LBA) of the drive. The short test is time-restricted and limited in length—it does not scan the entire media surface, but does  
some fundamental tests and scans portions of the media.  
If DST encounters an error during either of these tests, it reports a fault condition. If the drive fails the test, remove it from  
service and return it to Seagate for service.  
5.2.6.1 DST failure definition  
The drive will present a “diagnostic failed” condition through the self-tests results value of the diagnostic log page if a  
functional failure is encountered during DST. The channel and servo parameters are not modified to test the drive more  
stringently, and the number of retries are not reduced. All retries and recovery processes are enabled during the test. If data  
is recoverable, no failure condition will be reported regardless of the number of retries required to recover the data.  
The following conditions are considered DST failure conditions:  
• Seek error after retries are exhausted  
• Track-follow error after retries are exhausted  
• Read error after retries are exhausted  
• Write error after retries are exhausted  
Recovered errors will not be reported as diagnostic failures.

5.2.6.2 Implementation  
This section provides all of the information necessary to implement the DST function on this drive.  
5.2.6.2.1  
State of the drive prior to testing  
The drive must be in a ready state before issuing the Send Diagnostic command. There are multiple reasons why a drive  
may not be ready, some of which are valid conditions, and not errors. For example, a drive may be in process of doing a  
format, or another DST. It is the responsibility of the host application to determine the “not ready” cause.  
While not technically part of DST, a Not Ready condition also qualifies the drive to be returned to Seagate as a failed drive.  
A Drive Not Ready condition is reported by the drive under the following conditions:  
• Motor will not spin  
• Motor will not lock to speed  
• Servo will not lock on track  
• Drive cannot read configuration tables from the disk  
In these conditions, the drive responds to a Test Unit Ready command with an 02/04/00 or 02/04/03 code.  
5.2.6.2.2  
Invoking DST  
To invoke DST, submit the Send Diagnostic command with the appropriate Function Code (001b for the short test or 010b for  
the extended test) in bytes 1, bits 5, 6, and 7.  
5.2.6.2.3  
Short and extended tests  
DST has two testing options:  
1. short  
2. extended  
These testing options are described in the following two subsections.  
Each test consists of three segments: an electrical test segment, a servo test segment, and a read/verify scan segment.  
Short test (Function Code: 001b)  
The purpose of the short test is to provide a time-limited test that tests as much of the drive as possible within 120 seconds.  
The short test does not scan the entire media surface, but does some fundamental tests and scans portions of the media. A  
complete read/verify scan is not performed and only factual failures will report a fault condition. This option provides a quick  
confidence test of the drive.  
Extended test (Function Code: 010b)  
The objective of the extended test option is to empirically test critical drive components. For example, the seek tests and on-  
track operations test the positioning mechanism. The read operation tests the read head element and the media surface.  
The write element is tested through read/write/read operations. The integrity of the media is checked through a read/verify  
scan of the media. Motor functionality is tested by default as a part of these tests.  
The anticipated length of the Extended test is reported through the Control Mode page.

5.2.6.2.4  
Log page entries  
When the drive begins DST, it creates a new entry in the Self-test Results Log page. The new entry is created by inserting a  
new self-test parameter block at the beginning of the self-test results log parameter section of the log page. Existing data will  
be moved to make room for the new parameter block. The drive reports 20 parameter blocks in the log page. If there are  
more than 20 parameter blocks, the least recent parameter block will be deleted. The new parameter block will be initialized  
as follows:  
1. The Function Code field is set to the same value as sent in the DST command  
2. The Self-Test Results Value field is set to Fh  
3. The drive will store the log page to non-volatile memory  
After a self-test is complete or has been aborted, the drive updates the Self-Test Results Value field in its Self-Test Results  
Log page in non-volatile memory. The host may use Log Sense to read the results from up to the last 20 self-tests performed  
by the drive. The self-test results value is a 4-bit field that reports the results of the test. If the field is set to zero, the drive  
passed with no errors detected by the DST. If the field is not set to zero, the test failed for the reason reported in the field.  
The drive will report the failure condition and LBA (if applicable) in the Self-test Results Log parameter. The Sense key, ASC,  
ASCQ, and FRU are used to report the failure condition.  
5.2.6.2.5  
Abort  
There are multiple ways to abort a diagnostic. Two examples are: using a SCSI Bus Reset or a Bus Device message to abort  
the diagnostic  
To abort a DST executing in background mode, use the abort code in the DST Function Code field. This will cause a 01 (self-  
test aborted by the application client) code to appear in the self-test results values log. All other abort mechanisms will be  
reported as a 02 (self-test routine was interrupted by a reset condition).  
5.2.7 Product warranty  
Shipping  
When transporting or shipping a drive, use only a Seagate-approved container. Keep the original box. Seagate approved  
containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids  
the drive warranty.  
Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit. Contact an  
authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier  
experienced in handling computer equipment.  
Storage  
The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives should be  
stored in the original unopened Seagate shipping packaging when ever possible. Once the drive is removed from the  
Seagate original packaging the recommended maximum period between drive operation cycles is 30 days. During any  
storage period the drive non-operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic  
and electrical field specifications should be followed.  
Product repair and return information  
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction  
any third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.

6.0 PHYSICAL/ELECTRICAL SPECIFICATIONS  
This section provides information relating to the physical and electrical characteristics of the drive.  
6.1  
POWERCHOICETM POWER MANAGEMENT  
Drives using the load/unload architecture provide programmable power management to tailor systems for performance and  
greater energy efficiency.  
The table below lists the supported PowerChoice modes. The further down in the table, the more power savings can be  
realized. For example, Idle_B mode results in greater power savings than Idle_A mode. Standby modes results in the  
greatest power savings.  
PowerChoice modes

Reduced electronics  
Idle_B  
Heads unloaded. Disks spinning at full RPM  
Heads unloaded. Disks spinning at reduced RPM  
Heads unloaded. Disks spinning at reduced RPM  
Heads unloaded. Motor stopped (disks not spinning)  
Idle_C  
Standby_Y  
Standby_Z  
PowerChoiceTM can be invoked using one of these two methods:  
• Power Condition mode page method—Enable and initialize the idle condition timers and/or the standby condition timers.  
The timer values are based on the values set in the Power Condition mode page.  
• START STOP UNIT command method—Use the START STOP UNIT command (OPERATION CODE 1Bh). This allows  
the host to directly transition the drive to any supported PowerChoice mode.  
If both the Power Condition mode page and START STOP UNIT command methods are used, the START STOP UNIT  
command request takes precedence over the Power Condition mode page power control and may disable the idle condition  
and standby condition timers. The REQUEST SENSE command reports the current PowerChoice state if active and also the  
method by which the drive entered the PowerChoice state.  
When the drive receives a command, all power condition timers are suspended if they were enabled via the Power Condition  
mode page. Once all outstanding commands are processed, the power condition timers are reinitialized to the values defined  
in the Power Condition mode page.

DC POWER REQUIREMENTS  
The voltage and current requirements for a single drive are shown below. Values indicated apply at the drive connector.  
The standard drive models and the SED drive models have identical hardware, however the security and encryption portion  
of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V  
supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on  
the 12V supply.

General DC power requirement notes.  
1. Minimum current loading for each supply voltage is not less than 1.7% of the maximum operating current shown.  
2. The +5V and +12V supplies should employ separate ground returns.  
3. Where power is provided to multiple drives from a common supply, careful consideration for individual drive power  
requirements should be noted. Where multiple units are powered on simultaneously, the peak starting current must be  
available to each device.  
4. Parameters, other than spindle start, are measured after a 10-minute warm up.  
5. No terminator power.  
6.3.1 Conducted noise immunity  
Noise is specified as a periodic and random distribution of frequencies covering a defined frequency range. Maximum  
allowed noise values given below are peak-to-peak measurements and apply at the drive power connector.

The drive meets the operating specifications over a 41°F to 131°F (5°C to 55°C) drive case temperature range with a  
maximum temperature gradient of 36°F (20°C) per hour.  
The maximum allowable drive case temperature is 140°F (60°C).  
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal case tempera-  
ture. The rated MTBF is based upon a sustained case temperature of 122°F (50°C). Occasional excursions in operating  
temperature between the rated MTBF temperature and the maximum drive operating case temperature may occur with-  
out impact to the rated MTBF. However continual or sustained operation at case temperatures beyond the rated MTBF  
temperature will degrade the drive MTBF and reduce product reliability.  
Air flow may be required to achieve consistent nominal case temperature values (see Section 9.2). To confirm that the  
required cooling is provided for the electronics and HDA, place the drive in its final mechanical configuration, and perform  
random write/read operations. After the temperatures stabilize, measure the case temperature of the drive. See Figure 4  
for HDA temperature checkpoint.  
b. Non-operating  
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification  
assumes that the drive is packaged in the shipping container designed by Seagate for use with drive.

6.5.4 Shock and vibration  
Shock and vibration limits specified in this document are measured directly on the drive chassis. If the drive is installed in an  
enclosure to which the stated shock and/or vibration criteria is applied, resonances may occur internally to the enclosure  
resulting in drive movement in excess of the stated limits. If this situation is apparent, it may be necessary to modify the  
enclosure to minimize drive movement.  
The limits of shock and vibration defined within this document are specified with the drive mounted by any of the four  
6.5.4.1 Shock  
a. Operating—normal  
The drive, as installed for normal operation, shall operate error free while subjected to intermittent shock not exceeding:  
• 40 Gs at a maximum duration of 11ms (half sinewave)  
• 25 Gs at a maximum duration of 2ms (half sinewave)  
Shock may be applied in the X, Y, or Z axis. Shock is not to be repeated more than once every 2 seconds.  
b. Non-operating  
The limits of non-operating shock shall apply to all conditions of handling and transportation. This includes both isolated  
drives and integrated drives.  
The drive subjected to nonrepetitive shock not exceeding the three values below, shall not exhibit device damage or per-  
formance degradation.  
• 80 Gs at a maximum duration of 11ms (half sinewave)  
• 400 Gs at a maximum duration of 2ms (half sinewave)  
• 300 Gs at a maximum duration of 0.5ms (half sinewave)  
Shock may be applied in the X, Y, or Z axis.  
c. Packaged  
Seagate finished drive bulk packs are designed and tested to meet or exceed applicable ISTA and ASTM standards. Vol-  
ume finished drives will be shipped from Seagate factories on pallets to minimize freight costs and ease material han-  
dling. Seagate finished drive bulk packs may be shipped individually. For less than full shipments, instructions are printed  
on the bulk pack carton for minimum drive quantities and proper drive placement.

6.5.5 Air cleanliness  
The drive is designed to operate in a typical office environment with minimal environmental control.  
6.5.6 Corrosive environment  
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light industrial  
environments containing sulfurous gases, chlorine and nitric oxide, classes G and H per ASTM B845. However, this  
accelerated testing cannot duplicate every potential application environment.  
Users should use caution exposing any electronic components to uncontrolled chemical pollutants and corrosive chemicals  
as electronic drive component reliability can be affected by the installation environment. The silver, copper, nickel and gold  
films used in Seagate products are especially sensitive to the presence of sulfide, chloride, and nitrate contaminants. Sulfur  
is found to be the most damaging. In addition, electronic components should never be exposed to condensing water on the  
surface of the printed circuit board assembly (PCBA) or exposed to an ambient relative humidity greater than 95%. Materials  
used in cabinet fabrication, such as vulcanized rubber, that can outgas corrosive compounds should be minimized or  
eliminated. The useful life of any electronic equipment may be extended by replacing materials near circuitry with sulfide-free  
alternatives.  
6.5.7 Acoustics  
Sound power during idle mode shall be 3.1 bels typical when measured to ISO 7779 specification.  
There will not be any discrete tones more than 9 dB above the masking noise on typical drives when measured according to  
Seagate specification 30553-001. There will not be any tones more than 24 dB above the masking noise on any drive.

7.0 ABOUT FIPS  
The Federal Information Processing Standard (FIPS) Publication 140-2 is a U.S. Government Computer Security Standard  
used to accredit cryptographic modules. It is titled 'Security Requirements for Cryptographic Modules (FIPS PUB 140-2)' and  
is issued by the National Institute of Standards and Technology (NIST).  
Purpose  
This standard specifies the security requirements that will be satisfied by a cryptographic module utilized within a security  
system protecting sensitive but unclassified information. The standard provides four increasing, qualitative levels of security:  
Level 1, Level 2, Level 3 and Level 4. These levels are intended to cover the wide range of potential applications and  
environments in which cryptographic modules may be employed.  
Validation Program  
Products that claim conformance to this standard are validated by the Cryptographic Module Validation Program (CMVP)  
which is a joint effort between National Institute of Standards and Technology (NIST) and the Communications Security  
Establishment (CSE) of the Government of Canada. Products validated as conforming to FIPS 140-2 are accepted by the  
Federal agencies of both countries for the protection of sensitive information (United States) or Designated Information  
(Canada).  
In the CMVP, vendors of cryptographic modules use independent, accredited testing laboratories to have their modules  
tested. National Voluntary Laboratory Accreditation Program (NVLAP) accredited laboratories perform cryptographic module  
compliance/conformance testing.  
Seagate Enterprise SED  
accredited lab to satisfy FIPS 140-2 Level 2 requirements. In order to operate in FIPS Approved Mode of Operation, these  
140-1/1401vend.htm, and search for “Seagate”.  
Security Level 2  
Security Level 2 enhances the physical security mechanisms of a Security Level 1 cryptographic module by adding the  
requirement for tamper-evidence, which includes the use of tamper-evident coatings or seals on removable covers of the  
module. Tamper-evident coatings or seals are placed on a cryptographic module so that the coating or seal must be bro-  
ken to attain physical access to the critical security parameters (CSP) within the module. Tamper-evident seals (example  
shown in Figure 7, page 27) are placed on covers to protect against unauthorized physical access. In addition Security  
Level 2 requires, at a minimum, role-based authentication in which a cryptographic module authenticates the authorization  
of an operator to assume a specific role and perform a corresponding set of services.

8.0 ABOUT SELF-ENCRYPTING DRIVES  
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as  
“protection of data at rest.” These drives are compliant with the Trusted Computing Group (TCG) Enterprise Storage  
The Trusted Computing Group (TCG) is an organization sponsored and operated by companies in the computer, storage  
and digital communications industry. Seagate’s SED models comply with the standards published by the TCG.  
To use the security features in the drive, the host must be capable of constructing and issuing the following two SCSI  
commands:  
• Security Protocol Out  
• Security Protocol In  
These commands are used to convey the TCG protocol to and from the drive in their command payloads.  
8.1  
DATA ENCRYPTION  
Encrypting drives use one inline encryption engine for each port, employing AES-256 data encryption in Cipher Block  
Chaining (CBC) mode to encrypt all data prior to being written on the media and to decrypt all data as it is read from the  
media. The encryption engines are always in operation and cannot be disabled.  
The 32-byte Data Encryption Key (DEK) is a random number which is generated by the drive, never leaves the drive, and is  
inaccessible to the host system. The DEK is itself encrypted when it is stored on the media and when it is in volatile  
temporary storage (DRAM) external to the encryption engine. A unique data encryption key is used for each of the drive's  
8.2  
CONTROLLED ACCESS  
The drive has two security providers (SPs) called the "Admin SP" and the "Locking SP." These act as gatekeepers to the  
drive security services. Security-related commands will not be accepted unless they also supply the correct credentials to  
prove the requester is authorized to perform the command.  
8.2.1 Admin SP  
Admin SP is available using the SID (Secure ID) password or the MSID (Manufacturers Secure ID) password.  
8.2.2 Locking SP  
The Locking SP controls read/write access to the media and the cryptographic erase feature. Access to the Locking SP is  
available using the BandMasterX or EraseMaster passwords. Since the drive owner can define up to 16 data bands on the  
drive, each data band has its own password called BandMasterX where X is the number of the data band (0 through 15).  
8.2.3 Default password  
When the drive is shipped from the factory, all passwords are set to the value of MSID. This 32-byte random value can only  
be read by the host electronically over the interface. After receipt of the drive, it is the responsibility of the owner to use the  
default MSID password as the authority to change all other passwords to unique owner-specified values.

8.3  
RANDOM NUMBER GENERATOR (RNG)  
The drive has a 32-byte hardware RNG that it is uses to derive encryption keys or, if requested to do so, to provide random  
numbers to the host for system use, including using these numbers as Authentication Keys (passwords) for the drive’s  
Admin and Locking SPs.  
8.4  
DRIVE LOCKING  
the individual bands.  
The variable "LockOnReset" should be set to "PowerCycle" to ensure that the data bands will be locked if power is lost. In  
addition "ReadLockEnabled" and "WriteLockEnabled" must be set to true in the locking table in order for the bands  
"LockOnReset" setting of "PowerCycle" to actually lock access to the band when a "PowerCycle" event occurs. This  
scenario occurs if the drive is removed from its cabinet. The drive will not honor any data read or write requests until the  
bands have been unlocked. This prevents the user data from being accessed without the appropriate credentials when the  
drive has been removed from its cabinet and installed in another system.  
When the drive is shipped from the factory, the firmware download port is unlocked.  
8.5  
DATA BANDS  
When shipped from the factory, the drive is configured with a single data band called Band 0 (also known as the Global Data  
Band) which comprises LBA 0 through LBA max. The host may allocate Band1 by specifying a start LBA and an LBA range.  
The real estate for this band is taken from the Global Band. An additional 14 Data Bands may be defined in a similar way  
(Band2 through Band15) but before these bands can be allocated LBA space, they must first be individually enabled using  
the EraseMaster password.  
Data bands cannot overlap but they can be sequential with one band ending at LBA (x) and the next beginning at LBA (x+1).  
Each data band has its own drive-generated encryption key and its own user-supplied password. The host may change the  
8.6  
CRYPTOGRAPHIC ERASE  
A significant feature of SEDs is the ability to perform a cryptographic erase. This involves the host telling the drive to change  
the data encryption key for a particular band. Once changed, the data is no longer recoverable since it was written with one  
key and will be read using a different key. Since the drive overwrites the old key with the new one, and keeps no history of  
key changes, the user data can never be recovered. This is tantamount to an instantaneous data erase and is very useful if  
the drive is to be scrapped or redispositioned.

8.7  
AUTHENTICATED FIRMWARE DOWNLOAD  
In addition to providing a locking mechanism to prevent unwanted firmware download attempts, the drive also only accepts  
download files which have been cryptographically signed by the appropriate Seagate Design Center.  
Three conditions must be met before the drive will allow the download operation:  
1. The download must be an SED file. A standard (base) drive (non-SED) file will be rejected.  
2. The download file must be signed and authenticated.  
3. As with a non-SED drive, the download file must pass the acceptance criteria for the drive. For example it must be appli-  
cable to the correct drive model, and have compatible revision and customer status.  
8.8  
POWER REQUIREMENTS  
The standard drive models and the SED drive models have identical hardware, however the security and encryption portion  
of the drive controller ASIC is enabled and functional in the SED models. This represents a small additional drain on the 5V  
supply of about 30mA and a commensurate increase of about 150mW in power consumption. There is no additional drain on  
8.9  
SUPPORTED COMMANDS  
The SED models support the following two commands in addition to the commands supported by the standard (non-SED)  
• Security Protocol Out (B5h)  
• Security Protocol In (A2h)  
8.10 SANITIZE - CRYPTOGRAPHIC ERASE  
This command cryptographically erases all user data on the drive by destroying the current data encryption key and  
replacing it with a new data encryption key randomly generated by the drive. Sanitize CRYPTOGRAPHIC ERASE is a SCSI  
CDB Op code 48h and selecting the service action code 3 (CRYPTOGRAPHIC ERASE)  
8.11 REVERTSP  
The SED models will support the RevertSP feature which erases all data in all bands on the device and returns the contents  
of all SPs (Security Providers) on the device to their original factory state. In order to execute the RevertSP method the  
unique PSID (Physical Secure ID) printed on the drive label must be provided. PSID is not electronically accessible and can  
only be manually read from the drive label or scanned in via the 2D barcode.

9.0 DEFECT AND ERROR MANAGEMENT  
Seagate continues to use innovative technologies to manage defects and errors. These technologies are designed to  
increase data integrity, perform drive self-maintenance, and validate proper drive operation.  
SCSI defect and error management involves drive internal defect/error management and SAS system error considerations  
(errors in communications between the initiator and the drive). In addition, Seagate provides the following technologies used  
to increase data integrity and drive reliability:  
• Background Media Scan (see Section 9.4)  
• Deferred Auto-Reallocation (see Section 9.5)  
• Idle Read After Write (see Section 9.6)  
The read error rates and specified storage capacities are not dependent on host (initiator) defect management routines.  
9.1  
DRIVE INTERNAL DEFECTS/ERRORS  
During the initial drive format operation at the factory, media defects are identified, tagged as being unusable, and their  
locations recorded on the drive primary defects list (referred to as the “P’ list and also as the ETF defect list). At factory  
format time, these known defects are also reallocated, that is, reassigned to a new place on the medium and the location  
listed in the defects reallocation table. The “P” list is not altered after factory formatting. Locations of defects found and  
reallocated during error recovery procedures after drive shipment are listed in the “G” list (defects growth list). The “P” and  
“G” lists may be referenced by the initiator using the Read Defect Data command.  
Details of the SCSI commands supported by the drive are described in the SAS Interface Manual. Also, more information on  
the drive Error Recovery philosophy is presented in the SAS Interface Manual.  
9.2  
DRIVE ERROR RECOVERY PROCEDURES  
When an error occurs during drive operation, the drive, if programmed to do so, performs error recovery procedures to  
attempt to recover the data. The error recovery procedures used depend on the options previously set in the Error Recovery  
Parameters mode page. Error recovery and defect management may involve using several SCSI commands described in  
the SCSI Interface Manual. The drive implements selectable error recovery time limits required in video applications.  
The error recovery scheme supported by the drive provides a way to control the total error recovery time for the entire  
command in addition to controlling the recovery level for a single LBA. The total amount of time spent in error recovery for a  
command can be limited using the Recovery Time Limit bytes in the Error Recovery mode page. The total amount of time  
spent in error recovery for a single LBA can be limited using the Read Retry Count or Write Retry Count bytes in the Error  
Recovery mode page.  
The drive firmware error recovery algorithms consist of 20 levels for read recoveries and six levels for write. Each level may  
consist of multiple steps, where a step is defined as a recovery function involving a single re-read or re-write attempt. The  
maximum level used by the drive in LBA recovery is determined by the read and write retry counts.  
Table 2 equates the read and write retry count with the maximum possible recovery time for read and write recovery of  
individual LBAs. The times given do not include time taken to perform reallocations. Reallocations are performed when the  
ARRE bit (for reads) or AWRE bit (for writes) is one, the RC bit is zero, and the recovery time limit for the command has not  
yet been met. Time needed to perform reallocation is not counted against the recovery time limit.  
When the RC bit is one, reallocations are disabled even if the ARRE or AWRE bits are one. The drive will still perform data  
recovery actions within the limits defined by the Read Retry Count, Write Retry Count, and Recovery Time Limit parameters.  
However, the drive does not report any unrecovered errors.

e.g. 1 ~ 5%

20 ~ 100%  
Setting these retry counts to a value below the default setting could result in degradation of the unrecovered error rate. For  
example, suppose the read/write recovery page has the RC bit = 0 and if the read retry count is set to 5, this means ~ 25% of  
error recovery will be executed which consumes 621.62 ms (please refer to the table above). If the limit is reached and a  
LBA has not yet been recovered (i.e. requires retries beyond 621.62 ms), the command will end with Check Condition status  
report and unrecoverable read error will be reported.  
9.3  
SAS SYSTEM ERRORS  
Information on the reporting of operational errors or faults across the interface is given in the SAS Interface Manual. The  
SSP Response returns information to the host about numerous kinds of errors or faults. The Receive Diagnostic Results  
reports the results of diagnostic operations performed by the drive.  
Status returned by the drive to the initiator is described in the SAS Interface Manual. Status reporting plays a role in systems  
error management and its use in that respect is described in sections where the various commands are discussed.

9.4  
BACKGROUND MEDIA SCAN  
Background Media Scan (BMS) is a self-initiated media scan. BMS is defined in the T10 document SPC-4 available from the  
T10 committee. BMS performs sequential reads across the entire pack of the media while the drive is idle. In RAID arrays,  
BMS allows hot spare drives to be scanned for defects prior to being put into service by the host system. On regular duty  
drives, if the host system makes use of the BMS Log Page, it can avoid placing data in suspect locations on the media.  
Unreadable and recovered error sites will be logged or reallocated per ARRE/AWRE settings.  
With BMS, the host system can consume less power and system overhead by only checking BMS status and results rather  
than tying up the bus and consuming power in the process of host-initiated media scanning activity.  
Since the background scan functions are only done during idle periods, BMS causes a negligible impact to system  
performance. The first BMS scan for a newly manufactured drive is performed as quickly as possible to verify the media and  
protect data by setting the “Start time after idle” to 5ms, all subsequent scans begin after 500ms of idle time. Other features  
that normally use idle time to function will function normally because BMS functions for limited time bursts then suspends  
activity to allow other background functions to operate.  
BMS interrupts immediately to service host commands from the interface bus while performing reads. BMS will complete any  
BMS-initiated error recovery prior to returning to service host-initiated commands. Overhead associated with a return to host-  
servicing activity from BMS only impacts the first command that interrupted BMS, this results in a typical delay of about 1ms.  
9.5  
DEFERRED AUTO-REALLOCATION  
Deferred Auto-Reallocation (DAR) simplifies reallocation algorithms at the system level by allowing the drive to reallocate  
unreadable locations on a subsequent write command. Sites are marked for DAR during read operations performed by the  
drive. When a write command is received for an LBA marked for DAR, the auto-reallocation process is invoked and attempts  
to rewrite the data to the original location. If a verification of this rewrite fails, the sector is re-mapped to a spare location.  
This is in contrast to the system having to use the Reassign Command to reassign a location that was unreadable and then  
generate a write command to rewrite the data. DAR is most effective when AWRE and ARRE are enabled—this is the default  
setting from the Seagate factory. With AWRE and ARRE disabled DAR is unable to reallocate the failing location and will  
report an error sense code indicating that a write command is being attempted to a previously failing location.  
9.6  
IDLE READ AFTER WRITE  
Idle Read After Write (IRAW) utilizes idle time to verify the integrity of recently written data. During idle periods, no active  
system requests, the drive reads recently written data from the media and compares it to valid write command data resident  
in the drives data buffer. Any sectors that fail the comparison result in the invocation of a rewrite and auto-reallocation  
process. The process attempts to rewrite the data to the original location. If a verification of this rewrite fails, the sector is re-  
mapped to a spare location.

9.7  
PROTECTION INFORMATION (PI)  
Protection Information is intended as a standardized approach to system level LRC traditionally provided by systems using  
520 byte formatted LBAs. Drives formatted with PI information provide the same, common LBA count (i.e. same capacity  
point) as non-PI formatted drives. Sequential performance of a PI drive will be reduced by approximately 1.56% due to the  
extra overhead of PI being transferred from the media that is not calculated as part of the data transferred to the host. To  
determine the full transfer rate of a PI drive, transfers should be calculated by adding the 8 extra bytes of PI to the transferred  
LBA length, i.e. 512 + 8 = 520. PI formatted drives are physically formatted to 520 byte sectors that store 512 bytes of  
customer data with 8 bytes of Protection Information appended to it. The advantage of PI is that the Protection Information  
bits can be managed at the HBA and HBA driver level. Allowing a system that typically does not support 520 LBA formats to  
integrate this level of protection.  
Protection Information is valid with any supported LBA size. 512 LBA size is used here as common example.  
9.7.1 Levels of PI  
There are 4 types of Protection Information.  
Type 0 - Describes a drive that is not formatted with PI information bytes. This allows for legacy support in non-PI systems.  
Type 1 - Provides support of PI protection using 10 and 16 byte commands. The RDPROTECT and WRTPROTECT bits  
allow for checking control through the CDB. Eight bytes of Protection Information are transmitted at LBA boundaries across  
the interface if RDPROTECT and WRTPROTECT bits are nonzero values. Type 1 does not allow the use of 32 byte  
commands.  
Type 2 - Provides checking control and additional expected fields within the 32 byte CDBs. Eight bytes of Protection  
Information are transmitted at LBA boundaries across the interface if RDPROTECT and WRTPROTECT bits are nonzero  
values. Type 2 does allow the use of 10 and 16 byte commands with zero values in the RDPROTECT and WRTPROTECT  
fields. The drive will generate 8 bytes (e.g.0xFFFF) 8 bytes of Protection Information to be stored on the media, but the 8  
bytes will not be transferred to the host during a read command.  
Type 3 - Seagate products do not support Type 3.  
9.7.2 Setting and determining the current Type Level  
A drive is initialized to a type of PI by using the format command on a PI capable drive. Once a drive is formatted to a PI  
Type, it may be queried by a Read Capacity (16) command to report the PI type which it is currently formatted to. PI Types  
cannot coexist on a single drive. A drive can only be formatted to a single PI Type. It can be changed at anytime to a new  
Type but requires a low level format which destroys all existing data on the drive. No other vehicle for changing the PI type is  
provided by the T10 SBC3 specification.  
Type 1 PI format CDB command: 04 90 00 00 00 00, Write Buffer: 00 A0 00 00  
Type 2 PI format CDB command: 04 D0 00 00 00 00, Write Buffer: 00 A0 00 00  
9.7.3 Identifying a Protection Information drive  
The Standard Inquiry provides a bit to indicate if PI is support by the drive. Vital Product Descriptor (VPD) page 0x86  
provides bits to indicate the PI Types supported and which PI fields the drive supports checking.  
Note. For further details with respect to PI, please refer to SCSI Block Commands - 3 (SBC-3) Draft Standard docu-

SEAGATE RAID REBUILD ™  
Seagate RAID Rebuild is an industry standard feature to enable faster recovery from a failed drive in a RAID configuration. It improves  
RAID rebuild performance by extracting easily readable data from a failing drive. It quickly identifies blocks that would take longer to  
recover from the failed drive than to rebuild from the remaining drives in the RAID group.  
This feature allows host control of error recovery, maximizes up time, and minimizes likelihood of 2nd drive failure in a RAID  
configuration.

10.0 INSTALLATION  
Seagate Enterprise Performance 10K HDD disk drive installation is a plug-and-play process. There are no jumpers,  
switches, or terminators on the drive.  
SAS drives are designed to be used in a host system that provides a SAS-compatible backplane with bays designed to  
accommodate the drive. In such systems, the host system typically provides a carrier or tray onto which the drive needs to  
be mounted. Mount the drive to the carrier or tray provided by the host system using four M3 x 0.5 metric screws. When  
tightening the screws, use a maximum torque of 4.5 in-lb +/- 0.45 in-lb. Do not over-tighten or force the screws. Mount the  
drive in any orientation.  
Note. SAS drives are designed to be attached to the host system without I/O or power cables. If the intent is to use the  
drive in a non-backplane host system, connecting the drive using high-quality cables is acceptable as long as the  
I/O cable length does not exceed 10 meters (32.8 feet).  
Slide the carrier or tray into the appropriate bay in the host system using the instructions provided by the host system. This  
connects the drive directly to the system’s SAS connector. The SAS connector is normally located on a SAS backpanel. See  
Power is supplied through the SAS connector.  
The drive is shipped from the factory low-level formatted in 512-byte logical blocks. Reformat the drive only if a different  
logical block size needs to be selected.

10.1 DRIVE ORIENTATION  
The drive may be mounted in any orientation. All drive performance characterizations, however, have been done with the  
drive in horizontal (discs level) and vertical (drive on its side) orientations, which are the two preferred mounting orientations.  
10.2 COOLING  
Cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding the drive will  
The rack, cabinet, or drawer environment for the drive must provide heat removal from the electronics and head and disk  
assembly (HDA). Confirm that adequate heat removal is provided using the temperature measurement guidelines described  
the drive should be oriented, or air flow directed, so that the least amount of air flow resistance is created while providing air  
flow to the electronics and HDA. Also, the shortest possible path between the air inlet and exit should be chosen to minimize  
the travel length of air heated by the drive and other heat sources within the rack, cabinet, or drawer environment.

Note. Image of the HDA may not represent actual product, for reference only.  
10.3 DRIVE MOUNTING  
Mount the drive using the bottom or side mounting holes. If mounting the drive using the bottom holes, ensure to not  
physically distort the drive by attempting to mount it on a stiff, non-flat surface.  
The allowable mounting surface stiffness is 80 lb/in (14.0 N/mm). The following equation and paragraph define the allowable  
mounting surface stiffness:  
K x X = F < 15lb = 67N  
where K is the mounting surface stiffness (units in lb/in or N/mm) and X is the out-of-plane surface distortion (units in inches  
or millimeters). The out-of-plane distortion (X) is determined by defining a plane with three of the four mounting points fixed  
and evaluating the out-of-plane deflection of the fourth mounting point when a known force (F) is applied to the fourth point.  
10.4 GROUNDING  
Signal ground (PCBA) and HDA ground are connected together in the drive and cannot be separated by the user. The  
equipment in which the drive is mounted is connected directly to the HDA and PCBA with no electrically isolating shock  
mounts. If it is desired for the system chassis to not be connected to the HDA/PCBA ground, the systems integrator or user  
must provide a nonconductive (electrically isolating) method of mounting the drive in the host equipment.  
Increased radiated emissions may result if maximum surface area ground connection is not provided between system  
ground and drive ground. This is the system designer’s and integrator’s responsibility.

11.2 DUAL PORT SUPPORT  
Seagate Enterprise Performance 10K HDD SAS drives have two independent ports. These ports may be connected in the  
same or different SCSI domains. Each drive port has a unique SAS address.  
The two ports have the capability of independent port clocking (e.g. both ports can run at 6Gb/s or the first port can run at  
6Gb/s while the second port runs at 3Gb/s.) The supported link rates are 1.5, 3.0, or 6.0 Gb/s.  
Subject to buffer availability, the Seagate Enterprise Performance 10K HDD drives support:  
• Concurrent port transfers—The drive supports receiving COMMAND, TASK management transfers on both ports at the  
same time.  
• Full duplex—The drive supports sending XFER_RDY, DATA and RESPONSE transfers while receiving frames on both  
ports.

11.3.2 Mode Sense data  
The Mode Sense command provides a way for the drive to report its operating parameters to the initiator. The drive  
maintains four sets of mode parameters:  
1. Default values  
Default values are hard-coded in the drive firmware stored in flash E-PROM (nonvolatile memory) on the drive’s PCB.  
These default values can be changed only by downloading a complete set of new firmware into the flash E-PROM. An  
initiator can request and receive from the drive a list of default values and use those in a Mode Select command to set up  
new current and saved values, where the values are changeable.  
2. Saved values  
Saved values are stored on the drive’s media using a Mode Select command. Only parameter values that are allowed to  
be changed can be changed by this method. Parameters in the saved values list that are not changeable by the Mode  
Select command get their values from default values storage.  
When power is applied to the drive, it takes saved values from the media and stores them as current values in volatile  
memory. It is not possible to change the current values (or the saved values) with a Mode Select command before the  
drive achieves operating speed and is “ready.” An attempt to do so results in a “Check Condition” status.  
On drives requiring unique saved values, the required unique saved values are stored into the saved values storage  
location on the media prior to shipping the drive. Some drives may have unique firmware with unique default values also.  
On standard OEM drives, the saved values are taken from the default values list and stored into the saved values stor-  
age location on the media prior to shipping.  
3. Current values  
Current values are volatile values being used by the drive to control its operation. A Mode Select command can be used  
to change the values identified as changeable values. Originally, current values are installed from saved or default val-  
ues after a power on reset, hard reset, or Bus Device Reset message.  
4. Changeable values  
Changeable values form a bit mask, stored in nonvolatile memory, that dictates which of the current values and saved  
values can be changed by a Mode Select command. A one (1) indicates the value can be changed. A zero (0) indicates  
the value is not changeable. For example, in the table in Section 11.3.2, refer to Mode page 81, in the row entitled “CHG.”  
These are hex numbers representing the changeable values for Mode page 81. Note in columns 5 and 6 (bytes 04 and  
05), there is 00h which indicates that in bytes 04 and 05 none of the bits are changeable. Note also that bytes 06, 07, 09,  
10, and 11 are not changeable, because those fields are all zeros. In byte 02, hex value FF equates to the binary pattern  
11111111. If there is a zero in any bit position in the field, it means that bit is not changeable. Since all of the bits in byte  
02 are ones, all of these bits are changeable.  
The changeable values list can only be changed by downloading new firmware into the flash E-PROM.  
Note. Because there are often several different versions of drive control firmware in the total population of drives in the  
field, the Mode Sense values given in the following tables may not exactly match those of some drives.  
The following tables list the values of the data bytes returned by the drive in response to the Mode Sense command pages  
for SCSI implementation (see the SAS Interface Manual).  
DEF = Default value. Standard OEM drives are shipped configured this way.  
CHG = Changeable bits; indicates if default value is changeable.

11.4.7 Power  
The drive receives power (+5 volts and +12 volts) through the SAS device connector.  
Three +12 volt pins provide power to the drive, 2 short and 1 long. The current return for the +12 volt power supply is through  
the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins.  
Three +5 volt pins provide power to the drive, 2 short and 1 long. The current return for the +5 volt power supply is through  
the common ground pins. The supply current and return current must be distributed as evenly as possible among the pins.  
Current to the drive through the long power pins may be limited by the system to reduce inrush current to the drive during hot  
plugging.  
11.5 SIGNAL CHARACTERISTICS  
This section describes the electrical signal characteristics of the drive’s input and output signals. See Section 11.4.5 for  
signal type and signal name information.

The Ready LED Out signal is designed to pull down the cathode of an LED. The anode is attached to the proper +3.3 volt  
supply through an appropriate current limiting resistor. The LED and the current limiting resistor are external to the drive. See  
the next table for the output characteristics of the LED drive signals.

11.6 SAS-2 SPECIFICATION COMPLIANCE  
Seagate SAS-2 drives are entirely compatible with the latest SAS-2 Specification (T10/1760-D) Revision 16.  
The most important characteristic of the SAS-2 drive at 6Gb/s is that the receiver is capable of adapting the equalizer to  
optimize the receive margins. The SAS-2 drive has two types of equalizers:  
1. A Decision Feedback Equalizer (DFE) which utilizes the standard SAS-2 training pattern transmitted during the SNW-3  
training gap. The DFE circuit can derive an optimal equalization characteristic to compensate for many of the receive  
losses in the system.  
2. A Feed Forward Equalizer (FFE) optimized to provide balanced receive margins over a range of channels bounded by  
the best and worst case channels as defined by the relevant ANSI standard.  
11.7 ADDITIONAL INFORMATION  
Please contact the Seagate representative for SAS electrical details, if required.  
For more information about the Phy, Link, Transport, and Applications layers of the SAS interface, refer to the Seagate SAS  
Interface Manual, part number 100293071.  
For more information about the SCSI commands used by Seagate SAS drives, refer to the Seagate SCSI Commands  
Reference Manual, part number 100293068.
