Introduction  
This manual describes the functional, mechanical and interface specifications for the following Seagate  
SV35.3 Series® Serial ATA model drives:  
ST31000340SV  
ST3750330SV  
ST3500320SV  
ST3250310SV  
These drives provide the following key features:  
• High instantaneous (burst) data-transfer rates (up to 300 Mbytes per second).  
• Perpendicular recording heads and EPRML technology, for increased areal density.  
• State-of-the-art cache and on-the-fly error-correction algorithms.  
• Native Command Queueing with command ordering to increase performance in demanding applications.  
• Full-track multiple-sector transfer capability without local processor intervention.  
• Quiet operation.  
• SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.  
• Support for S.M.A.R.T. drive monitoring and reporting.  
• Supports latching SATA cables and connectors.

About the Serial ATA interface  
The Serial ATA 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 jump-  
ers or other configuration options.  
• Thinner and more flexible cabling for improved enclosure airflow and ease of installation.  
• Scalability to higher performance levels.  
In addition, Serial ATA makes the transition from parallel ATA easy by providing legacy software support. Serial  
ATA was designed to allow you to install a Serial ATA host adapter and Serial ATA disc drive in your current  
system and expect all of your existing applications to work as normal.  
The Serial ATA interface connects each disc drive in a point-to-point configuration with the Serial ATA host  
adapter. There is no master/slave relationship with Serial ATA devices like there is with parallel ATA. If two  
drives are attached on one Serial ATA 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.  
Note. The host adapter may, optionally, emulate a master/slave environment to host software where two  
devices on separate Serial ATA 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 Serial ATA  
environment.  
The Serial ATA 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 Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device regis-  
ters, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For addi-  
tional information about how Serial ATA emulates parallel ATA, refer to the “Serial ATA: High Speed Serialized

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 5,000 measurements of seeks between  
random tracks, less overhead.

Note. 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.

The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 1 on page 24.  
2.8.1 Power consumption  
Power specifications  
Power requirements for the drives are listed in the table on page 9. 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-msec  
delay, then a 16-sector read followed by a 32-msec 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 10 MHz.  
• 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 10 MHz.  
Note. 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 disc  
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 disc 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 disc access is necessary.

Acoustics  
Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All mea-  
surements 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.  
Note. For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined  
by the following equation:  
(Number of seeks per second = 0.4 / (average latency + average access time)

Reliability  
2.12.1  
Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)  
The product shall achieve an Annualized Failure Rate (AFR) of 0.80% (MTBF of 1+ million hours) when  
operated in an environment of ambient air temperatures of 25°C, assuming delta between ambient air  
temperature and HDD case temperature is less than 15°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 Digital Video Surveillance computer  
environments:  
• 8760 power-on-hours per year.  
• 10,000 average motor start/stop cycles per year.  
• Operations at nominal voltages.  
• Temperatures outside the specifications in Section 2.9 may reduce the product reliability.  
• Normal I/O duty cycle for desktop personal computers. Operation at excessive I/O duty cycle may degrade  
product reliability.  
The surveillance environment of power-on-hours, temperature, and I/O duty cycle affect the product AFR and  
MTBF. The AFR and MTBF will be degraded if used in a enterprise application.

disc drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursu-  
ant to Subpart J, Part 15 of the FCC rules. Operation with noncertified assemblies is likely to result in interfer-  
ence 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 installa-  
tion. 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.  
SV35.3 Series Serial ATA Product Manual, Rev. B  
19

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, chlo-  
ride, 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 vulca-  
nized 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.

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 dis-  
charge (ESD) hazards. Observe the following standard handling and static-discharge precautions:  
Caution:  
• 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.  
• 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.  
SV35.3 Series Serial ATA Product Manual, Rev. B  
23  
                   
3.2  
Configuring the drive  
Each drive on the Serial ATA interface connects point-to-point with the Serial ATA 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 Serial ATA 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.  
Serial ATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive  
for proper operation; however, if you connect the drive and receive a “drive not detected” error, your SATA-  
equipped motherboard or host adapter may use a chipset that does not support SATA speed autonegotiation. If  
you have a motherboard or host adapter that does not support autonegotiation:  
• Install a jumper as shown in Figure 1 below to limit the data transfer rate to 1.5 Gbits per second (and leave  
the drive connected to the SATA-equipped motherboard or host adapter that doesn’t support auto-negotiation)  
or  
• Install a SATA host adapter that supports auto-negotiation, leave the drive jumper block set to “Normal  
operation” (see Figure 1 below), and connect the drive to that adapter. This option has the benefit of not limiting  
the drive to a 1.5 Gbits/sec transfer rate.

Serial ATA cables and connectors  
The Serial ATA interface cable consists of four conductors in two differential pairs, plus three ground connec-  
tions. The cable size may be 30 to 26 AWG with a maximum length of one meter (39.37 inches). See Table 6  
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 1.

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. See Figure 1 on page 25 for drive mounting dimensions. Follow these important  
mounting precautions when mounting the drive:  
• Allow a minimum clearance of 0.030 inches (0.76 mm) 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 (3.81 mm) into the bottom or side mounting holes.  
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).

Identify Device command  
The Identify Device command (command code ECH) transfers information about the drive to the host following  
power up. The data is organized as a single 512-byte block of data, whose contents are shown in Table 7 on  
page 30. All reserved bits or words should be set to zero. Parameters listed with an “x” are drive-specific or  
vary with the state of the drive. See Section 2.0 on page 3 for default parameter settings.  
The following commands contain drive-specific features that may not be included in the Serial ATA specifica-  
tion.

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 inter-  
rupt. 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:

S.M.A.R.T. commands  
S.M.A.R.T. provides near-term failure prediction for disc drives. When S.M.A.R.T. is enabled, the drive moni-  
tors 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 elimi-  
nates unnecessary drive returns. The diagnostic software ships with all new drives and is also available at:  
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.
