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

Seagate Desktop HDD Product Manual, Rev. J 2

www.seagate.com Introduction

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 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 SA TA 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.

Note

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.

2.8 Power specifications

The drive receives DC power (+5V or +12V) through a native SA TA power connector. Refer to Figure 1 on page 19.

2.8.1 Power consumption

Power requirements for the drives are listed in Table 3, Table 4, Table 5 and Table 6. 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.

• 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.

2.8.2 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.

Note

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

2.8.3 Voltage tolerance

Voltage tolerance (including noise):

• 5V ±5%

• 12V +10% / -7.5%

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 power­management 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
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.

2.15 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.

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 mounting 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.

SA TA 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 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 9 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.

Each cable is keyed to ensure correct orientation. Desktop HDD drives support latching SATA connectors.

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 and Figure 3 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).

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

4.3.3 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://seatools.seagate.com.

This drive is shipped with S.M.A.R.T. features disabled. Users 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.
