1.1 About the SATA interface  
The Serial ATA (SATA) interface provides several advantages over the traditional (parallel) ATA interface. The primary  
advantages include:  
• Easy installation and configuration with true plug-and-play connectivity. It is not necessary to set any jumpers or other  
configuration options.  
• Thinner and more flexible cabling for improved enclosure airflow and ease of installation.  
• Scalability to higher performance levels.  
In addition, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was designed to  
allow you to install a SATA host adapter and SATA disk drive in your current system and expect all of your existing  
applications to work as normal.  
The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is no master/  
slave relationship with SATA devices like there is with parallel ATA. If two drives are attached on one SATA host adapter, the  
host operating system views the two devices as if they were both “masters” on two separate ports. This essentially means both  
drives behave as if they are Device 0 (master) devices.  
The host adapter may, optionally, emulate a master/slave environment to host software where two devices on  
separate SATA ports are represented to host software as a Device 0 (master) and Device 1 (slave) accessed at  
the same set of host bus addresses. A host adapter that emulates a master/slave environment manages two  
sets of shadow registers. This is not a typical SATA environment.  
Note  
The SATA host adapter and drive share the function of emulating parallel ATA device behavior to provide backward  
compatibility with existing host systems and software. The Command and Control Block registers, PIO and DMA data  
transfers, resets, and interrupts are all emulated.  
The SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the  
Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA  
emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 3.0”. The specification can be  
downloaded from www.sata-io.org.

Seek time  
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive  
diagnostics. The specifications in the table below are defined as follows:  
• Track-to-track seek time is an average of all possible single-track seeks in both directions.  
• Average seek time is a true statistical random average of at least 5000 measurements of seeks between random tracks, less  
overhead.

These drives are designed to consistently meet the seek times represented in this manual. Physical seeks,  
regardless of mode (such as track-to-track and average), are expected to meet the noted values. However,  
due to the manner in which these drives are formatted, benchmark tests that include command overhead or  
measure logical seeks may produce results that vary from these specifications.

Power specifications  
The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 6 on page 23.  
2.8.1  
Power consumption  
Power requirements for the drives are listed in Table 2:. Typical power measurements are based on an average of drives tested,  
under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.  
• Spinup power  
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.  
• Seek mode  
During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does not execute a  
read or write operation. Servo electronics are active. Seek mode power represents the worst-case power consumption, using  
only random seeks with read or write latency time. This mode is not typical and is provided for worst-case information.  
• Read/write power and current  
Read/write power is measured with the heads on track, based on a 16-sector write followed by a 32-ms delay, then a 16-  
sector read followed by a 32-ms delay.  
• Operating power and current  
Operating power is measured using 40 percent random seeks, 40 percent read/write mode (1 write for each 10 reads) and  
20 percent drive idle mode.  
• Idle mode power  
Idle mode power is measured with the drive up to speed, with servo electronics active and with the heads in a random track  
location.  
• Standby mode  
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/write electronics  
are in power-down mode..

Conducted noise  
Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12 volt line  
or an equivalent 15-ohm resistive load on the +5 volt line.  
• Using 12-volt power, the drive is expected to operate with a maximum of 120 mV peak-to-peak square-wave injected noise  
at up to 10MHz.  
• Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave injected noise at  
up to 10MHz.  
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

Power-management modes  
The drive provides programmable power management to provide greater energy efficiency. In most systems, you can control  
power management through the system setup program. The drive features the following power-management modes:

• Active mode  
The drive is in Active mode during the read/write and seek operations.  
• Idle mode  
The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disk access is  
necessary.  
• Standby mode  
The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the standby timer,  
the drive can also enter Standby mode automatically after the drive has been inactive for a specifiable length of time. The  
standby timer delay is established using a Standby or Idle command. In Standby mode, the drive buffer is enabled, the  
heads are parked and the spindle is at rest. The drive accepts all commands and returns to Active mode any time disk  
access is necessary.  
• Sleep mode  
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buffer is disabled,  
the heads are parked and the spindle is at rest. The drive leaves Sleep mode after it receives a Hard Reset or Soft Reset  
from the host. After receiving a reset, the drive exits Sleep mode and enters Standby mode with all current translation  
parameters intact.  
• Idle and Standby timers  
Each time the drive performs an Active function (read, write or seek), the standby timer is reinitialized and begins counting  
down from its specified delay times to zero. If the standby timer reaches zero before any drive activity is required, the drive  
makes a transition to Standby mode. In both Idle and Standby mode, the drive accepts all commands and returns to Active  
mode when disk access is necessary.

Extended Power Conditions - PowerChoiceTM  
Utilizing the load/unload architecture a programmable power management interface is provided to tailor systems for reduced  
power consumption and performance requirements.  
The table below lists the supported power conditions available in PowerChoice. Power conditions are ordered from highest  
power consumption (and shortest recovery time) to lowest power consumption (and longest recovery time) as follows: Idle_a  
power >= Idle_b power >= Idle_c power >= Standby_z power. The further you go down in the table, the more power savings  
is actualized. For example, Idle_b results in greater power savings than the Idle_a power condition. Standby results in the  
greatest power savings.

Each power condition has a set of current, saved and default settings. Default settings are not modifiable. Default and saved  
settings persist across power-on resets. The current settings do not persist across power-on resets. At the time of manufacture,  
the default, saved and current settings are in the Power Conditions log match.  
PowerChoice is invoked using one of two methods  
• Automatic power transitions which are triggered by expiration of individual power condition timers. These timer values may  
be customized and enabled using the Extended Power Conditions (EPC) feature set using the standardized Set Features  
command interface.  
• Immediate host commanded power transitions may be initiated using an EPC Set Features "Go to Power Condition"  
subcommand to enter any supported power condition. Legacy power commands Standby Immediate and Idle Immediate also  
provide a method to directly transition the drive into supported power conditions.  
PowerChoice exits power saving states under the following conditions  
• Any command which requires the drive to enter the PM0: Active state (media access)  
• Power on reset  
PowerChoice provides the following reporting methods for tracking purposes  
Check Power Mode Command  
• Reports the current power state of the drive  
Identify Device Command  
• EPC Feature set supported flag  
• EPC Feature enabled flag is set if at least one Idle power condition timer is enabled

Environmental limits  
Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part.  
Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C). Maximum wet bulb  
temperature is 82°F (28°C).  
The recommended storage period:  
• 1 year under controlled conditions of 34°C 90%RH or less  
• 90 days in uncontrolled storage conditions  
Note

Ambient temperature  
a Operating  
The drive meets the operating specifications over a 41°F to 140°F (5°C to 60°C) drive case temperature range with a  
maximum temperature gradient of 36°F (20°C) per hour.  
The maximum allowable drive case temperature is 60°C. See Figure 5 for HDA case temperature measurement location  
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal case  
temperature. The rated MTBF is based upon a sustained case temperature of 104°F (40°C). Occasional excursions in  
operating temperature between the rated MTBF temperature and the maximum drive operating case temperature may  
occur without impact to the rated MTBF temperature. 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 3.4). 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.  
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

Acoustics  
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All measurements are  
consistent with ISO document 7779. Sound power measurements are taken under essentially free-field conditions over a  
reflecting plane. For all tests, the drive is oriented with the cover facing upward.  
For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined by the  
following equation:  
Note  
(Number of seeks per second = 0.4 / (average latency + average access time

Test for Prominent Discrete Tones (PDTs)  
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this process is the use  
of the absolute threshold of hearing. Seagate uses this threshold curve (originated in ISO 389-7) to discern tone audibility and  
to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA-  
74 standards.

Reliability  
Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)  
2.13.1  
The product shall achieve an Annualized Failure Rate (AFR) of 1.1% (MTBF of 800 thousand hours) when operated at  
nominal power and typical case temperatures of 40°C. Operation at temperatures outside the specifications in Section 2.9 may  
increase the product AFR (decrease MTBF). AFR and MTBF are population statistics that are not relevant to individual units.  
AFR and MTBF specifications are based on the following assumptions for business critical storage system environments:  
•
•
•
•
8760 power-on-hours per year.  
Operations at nominal voltages.  
Temperatures outside the specifications in Section 2.9 may reduce the product reliability.  
A workload rate below the average annualized specified limits. Operation at excessive I/O duty cycle may degrade product  
reliability.  
The enterprise application nearline environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR  
and MTBF.

The MTBF specification for the drive assumes the I/O workload does not exceed the Average  
Annualized Workload Rate Limit of <180TB/year. Workloads exceeding the annualized rate may  
degrade the drive MTBF and impact product reliability. The Average Annualized Workload Rate Limit  
is in units of TB per year, or TB per 8760 power on hours.  
Workload Rate = TB transferred x ( 8760 / recorded power on hours).

subassembly, no Federal Communications Commission verification or certification of the device is required.  
Seagate has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disk drive,  
motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of  
the FCC rules. Operation with non-certified assemblies is likely to result in interference to radio and television reception.  
Radio and television interference. This equipment generates and uses radio frequency energy and if not installed and used in  
strict accordance with the manufacturer’s instructions, may cause interference to radio and television reception.  
This equipment is designed to provide reasonable protection against such interference in a residential installation. However,  
there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interference to  
radio or television, which can be determined by turning the equipment on and off, you are encouraged to try one or more of the  
following corrective measures:  
• Reorient the receiving antenna.  
• Move the device to one side or the other of the radio or TV.  
• Move the device farther away from the radio or TV.  
• Plug the computer into a different outlet so that the receiver and computer are on different branch outlets.

2.15 Environmental protection  
Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting  
certain chemical substances.  
2.15.1 European Union Restriction of Hazardous Substances (RoHS) Directive  
The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical substances,  
including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective July 2006. This  
drive is manufactured with components and materials that comply with the RoHS Directive.  
2.15.2 China Restriction of Hazardous Substances (RoHS) Directive  
This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table contains  
information mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic  
Information Products" Standard.  
"O" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is lower than the  
threshold defined by the China RoHS MCV Standard.  
"X" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is over the threshold  
defined by the China RoHS MCV Standard.  
2.16 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.  
2.17 Product warranty  
Beginning on the date of shipment to the customer and continuing for the period specified in your purchase contract, Seagate  
warrants that each product (including components and subassemblies) that fails to function properly under normal use due to  
defect in materials or workmanship or due to nonconformance to the applicable specifications will be repaired or replaced, at  
Seagate’s option and at no charge to the customer, if returned by customer at customer’s expense to Seagate’s designated

www.seagate.com  
facility in accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to  
the customer. For more detailed warranty information, refer to the standard terms and conditions of purchase for Seagate  
products on your purchase documentation.  
The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-3472. You  
can also determine remaining warranty using the Seagate web site (www.seagate.com). The drive serial number is required to  
determine remaining warranty information.  
Shipping  
When transporting or shipping a drive, use only a Seagate-approved container. Keep your 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 your  
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 whenever 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.

Configuring and Mounting the Drive  
This section contains the specifications and instructions for configuring and mounting the drive.  
3.1  
Handling and static-discharge precautions  
After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic discharge (ESD)  
hazards. Observe the following standard handling and static-discharge precautions:  
• Before handling the drive, put on a grounded wrist strap, or ground yourself frequently by touching the metal chassis of a  
computer that is plugged into a grounded outlet. Wear a grounded wrist strap throughout the entire installation procedure.  
• Handle the drive by its edges or frame only.  
• The drive is extremely fragile—handle it with care. Do not press down on the drive top cover.  
• Always rest the drive on a padded, antistatic surface until you mount it in the computer.  
• Do not touch the connector pins or the printed circuit board.  
Caution  
• Do not remove the factory-installed labels from the drive or cover them with additional labels. Removal voids the warranty.  
Some factory-installed labels contain information needed to service the drive. Other labels are used to seal out dirt and  
contamination.  
3.2  
Configuring the drive  
Each drive on the SATA interface connects point-to-point with the SATA host adapter. There is no master/slave relationship  
because each drive is considered a master in a point-to-point relationship. If two drives are attached on one SATA host adapter,  
the host operating system views the two devices as if they were both “masters” on two separate ports. Both drives behave as if  
they are Device 0 (master) devices.  
3.3  
SATA cables and connectors  
The SATA interface cable consists of four conductors in two differential pairs, plus three ground connections. The cable size  
may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). See Table 5 for connector pin definitions. Either  
end of the SATA signal cable can be attached to the drive or host.  
For direct backplane connection, the drive connectors are inserted directly into the host receptacle. The drive and the host  
receptacle incorporate features that enable the direct connection to be hot pluggable and blind mateable.  
For installations which require cables, you can connect the drive as illustrated in Figure 6.

3.4 Drive mounting  
You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-  
mounting holes. Refer to Figure 7 for drive mounting dimensions. Follow these important mounting precautions when  
mounting the drive:  
• Allow a minimum clearance of 0.030 inches (0.76mm) around the entire perimeter of the drive for cooling.  
• Use only 6-32 UNC mounting screws.  
• The screws should be inserted no more than 0.150 inch (3.81mm) into the bottom or side mounting holes.  
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

About Seagate Instant Secure Erase drives  
Self-encrypting drives (SEDs) offer encryption and security services for the protection of stored data, commonly known as  
“protection of data at rest”.  
4.1 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, cannot be disabled, and do not detract in any way from the  
performance of the drive.  
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 possible16 data  
bands (see Section 6.5).  
4.2 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.  
4.3 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  
the 12V supply. See the tables in Section 4.3 for power requirements on the standard (non-SED) drive models.  
4.4 RevertSP  
The SED models will support RevertSP feature where it 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.  
4.5 ATA Security Erase Unit Command on SED SATA drives  
The ATA SECURITY ERASE UNIT command shall support both the Normal and Enhanced erase modes with the following  
modifications/additions:  
• Normal Erase: Normal erase shall be accomplished by changing the media encryption key for the drive followed by an  
overwrite operation that repeatedly writes a single sector containing random data to the entire drive. The write operation  
shall bypass the media encryption. On reading back the overwritten sectors, the host will receive a decrypted version, using  
the new encryption key, of the random data sector (the returned data will not match what was written).  
• Enhanced Erase: Enhanced erase shall be accomplished by changing the media encryption key for the drive.  
4.6 Sanitize Feature Set on SED Drives  
The drive shall support the Sanitize Feature Set as defined in ANSI/INCITS ACS-2 with the exceptions and/or modifications  
described in this section.  
The drive shall not support the OVERWRITE EXT and BLOCK ERASE EXT sub-commands.  
Support of the SANITIZE FREEZE LOCK EXT command shall be determined on a customer-specific basis. OEM drives  
shall support the command.

5.1  
Hot-Plug compatibility  
Constellation CS Serial ATA drives incorporate connectors which enable you to hot plug these drives in accordance with the  
SATA Revision 3.0 specification. This specification can be downloaded from www.serialata.org.  
The drive motor must come to a complete stop (Ready to spindle stop time indicated in  
Section 3.7) prior to changing the plane of operation.This time is required to insure data  
integrity.

Set Features command  
This command controls the implementation of various features that the drive supports. When the drive receives this command,  
it sets BSY, checks the contents of the Features register, clears BSY and generates an interrupt. If the value in the register does  
not represent a feature that the drive supports, the command is aborted. Power-on default has the read look-ahead and write  
caching features enabled. The acceptable values for the Features register are defined as follows:  
02  
03  
Enable write cache (default).  
H

S.M.A.R.T. commands  
S.M.A.R.T. provides near-term failure prediction for disk drives. When S.M.A.R.T. is enabled, the drive monitors  
predetermined drive attributes that are susceptible to degradation over time. If self-monitoring determines that a failure is  
likely, S.M.A.R.T. makes a status report available to the host. Not all failures are predictable. S.M.A.R.T. predictability is  
limited to the attributes the drive can monitor. For more information on S.M.A.R.T. commands and implementation, see the  
Draft ATA-5 Standard.  
SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4H) that eliminates  
unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:  
http://www.seagate.com/support/downloads/seatools/.  
This drive is shipped with S.M.A.R.T. features disabled. You must have a recent BIOS or software package that supports  
S.M.A.R.T. to enable this feature. The table below shows the S.M.A.R.T. command codes that the drive uses.
