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.

Introduction
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

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.

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.

Drive 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 24.
2.8.1 Power consumption
Power requirements for the drives are listed in Table 2 and Table 3. 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 by simulating a typical PVR operating environment, using a 50% write, 50%
read algorithm.
• 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.
Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

• 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.

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
2.10.1 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.

2.14 Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemical substances.
2.14.1 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.
2.14.2 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

"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.
2.15 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.

3.0 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:
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.
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 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.
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.

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. See 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).

4.3.1 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 on page 28. 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 SATA specification.

4.3.2 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
Set transfer mode (based on value in Sector Count register).
Sector Count register values:
H
00 Set PIO mode to default (PIO mode 2).

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 D4 ) that eliminates
H
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.
