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 normally 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, 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.

Power specifications
The drive receives DC power (+5V) through a native SATA power connector.
2.9.1 Power consumption
Power requirements for the drives are listed in the table on page 8. Typical power measurements are based on
an average of drives tested, under nominal conditions, at 25°C ambient temperature.
• Spinup power
Spinup power is measured fromthe time ofpower-onto thetimethat 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 is measured based on
three random seek operations every 100 msecs. This mode is not typical.
• Read/write power and current
Read/write power is measured with the heads on track, based on three 63 sector read or write operations
every 100 msecs.
• 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.

• 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 in Self Refresh Low Power mode, 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 in Self Refresh Low Power mode, 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.

Test for Prominent Discrete Tones (PDTs)
Seagate follows the ECMA-74 standards for measurement and identification of PDTs. An exception to this pro-
cess is the use of the absolute threshold of hearing. Seagate uses the lower limit for the threshold curve* 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.
*Defined as the median curve given by ISO 389-7 (Tf curve) minus 10dB at all frequencies.

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 corro-
sive chemicals as electronic drive component reliability can be affected by the installation environment. The sil-
ver, 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 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:
• Keep the drive in the electrostatic discharge (ESD) bag until you are ready for installation to limit the drive’s
exposure to ESD.
• 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 only by its edges or frame.
• The drive is 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.

3.2
Configuring the drive
Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host
adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point
relationships. 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 means both drives behave as if they are
Device 0 (master) devices.
Serial ATA drives are designed for easy installation. It is normally not necessary to set any jumpers on this
drive for proper operation. If the host system does not support SATA 3Gb/s operation, place a jumper on pins 1
and 2 to limit the drive to 1.5Gb/s operation.

Identify Device command
The Identify Device command (command code EC ) transfers information about the drive to the host following
H
power up. The data is organized as a single 512-byte block of data, whose contents are shown in the table on
page 27. 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.
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-8 Standard.
SeaTools diagnostic software activates a built-in drive self-test (DST S.M.A.R.T. command for D4 ) that elimi-
H
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.
