When referring to drive capacity, one gigabyte, or GB, equals one billion bytes and one terabyte, or TB, equals one trillion bytes. Your computer’s operating system may use a different
standard of measurement and report a lower capacity. In addition, some of the listed capacity is used for formatting and other functions, and thus will not be available for data storage.
Actual quantities will vary based on various factors, including file size, file format, features and application software. Actual data rates may vary depending on operating environment and
other factors. The export or re-export of hardware or software containing encryption may be regulated by the U.S. Department of Commerce, Bureau of Industry and Security (for more

1.0 Introduction
This manual describes the functional, mechanical and interface specifications for the following
Seagate® Desktop HDD model drives:
ST4000DM000 ST3000DM003
These drives provide the following key features:
• High instantaneous (burst) data-transfer rates (up to 600MB per second).
• TGMR recording technology provides the drives with increased areal density.
• State-of-the-art cache and on-the-fly error-correction algorithms.
• Native Command Queuing with command ordering to increase performance in demanding applications.
• Quiet operation.
• Compliant with RoHS requirements in China and Europe.
• 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.
• Worldwide Name (WWN) capability uniquely identifies the drive.
1.1 About theSATAinterface
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 users to install a SATA host adapter and SATA disk drive in the current system and expect all of the 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 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 3.2”. The specification can be
downloaded from www.sata-io.org.
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
Note
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.

2.6 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.

Time-to-ready may be longer than normal if the drive power is removed without going through normal OS power down
procedures.
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
Note
which these drives are formatted, benchmark tests that include command overhead or measure logical seeks may
produce results that vary from these specifications.

2.8 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 1 on page 18.
2.8.1 Powerconsumption
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.
• Spin up power
Spin up power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
• 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 elec-
tronics are in power-down mode.

2.8.2 Conductednoise
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.
Note
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

2.8.4 Power-management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems, users can
control power management through the system setup program. The drive features the following power-management
modes:
Power modes Heads Spindle Buffer
Active Tracking Rotating Enabled
Idle Tracking Rotating Enabled
Standby Parked Stopped Enabled
Sleep Parked Stopped Disabled
• 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 dis-
abled, 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 trans-
lation 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 com-
mands and returns to Active mode when disk access is necessary.

2.10 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.

*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to
operational levels.
2.10.1TestforProminentDiscreteTones(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.
2.11 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in performance
when subjected to the radio frequency (RF) environments defined in Table 4.

2.13.3 FCC verification
These drives are intended to be contained solely within a personal computer or similar enclosure (not attached as an
external device). As such, each drive is considered to be a subassembly even when it is individually marketed to the
customer. As a 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, users 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.
If necessary, users should consult the dealer or an experienced radio/television technician for additional suggestions.
Users may find helpful the following booklet prepared by the Federal Communications Commission: How to Identify and
Resolve Radio-Television Interference Problems. This booklet is available from the Superintendent of Documents,
U.S. Government Printing Office, Washington, DC 20402. Refer to publication number 004-000-00345-4.

2.15 Corrosiveenvironment
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.

www.seagate.com Configuring and Mounting the Drive
3.0 ConfiguringandMountingtheDrive
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:
Caution
• Before handling the drive, put on a grounded wrist strap, or ground oneself 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 users 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.
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.
SATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive for proper
operation; however, if users connect the drive and receive a “drive not detected” error, the SATA-equipped motherboard or
host adapter may use a chipset that does not support SATA speed autonegotiation.
3.3 SATAcables 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, users can connect the drive as illustrated in Figure 1.

3.4 Drive mounting
Users 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 2 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).
