• High instantaneous (burst) data-transfer rates (up to 300 Mbytes per second).

• Perpendicular recording technology provides the drives with 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.

1.1 About the Serial ATA interface

The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The prim ary
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, Serial ATA makes the transition from parallel A TA 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 register s that shadow the content s of the traditional de vice regis­ters, referred to as the Shadow Register Block. All Serial ATA devices behave like Device 0 devices. For addi­tional information about how Serial ATA emulates parallel ATA, refer to the “S erial ATA: High Speed Serialized
AT Attachment” specification. The specification can be downloaded from www .serialata.org.

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 s tatistical random average of at le ast 5,000 measurements of seeks between
random tracks, less overhead.

*Typical seek times (msec) Read Write

Track-to-track <0.8 <1.0
Average <8.5 <10.0
Average latency: 4.16 4.16

*Measured in performance mode.
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.

2.7 Start/stop times

Power-on to Ready (sec) 15 (max)
Standby to Ready (sec) 15 (max)
Ready to spindle stop (sec) 10 (max)

2.8 Power specifications

The drive receives DC power (+5V or +12V) through a na tive SATA po wer connector. See Figure 4 on page 28.

2.8.1 Power consumption

Power requirements for the drives are listed in the t able on p ag e 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 op erating
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.

16 Barracuda ES Serial ATA Product Manual, Rev. B

• Operating power and current

Operating power is measured using 40 percent r andom seeks, 40 percent r ead/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.

Table 6: DC power requirements

*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.

2.8.1.1 Typical current profiles

Figure 1. Typical 5V startup and operation cu rre nt profile

Barracuda ES Serial ATA Product Manual, Rev. B 17

Figure 2. Typical 12V startup and operation current profile

2.8.2 Conducted noise

Input noise ripple is measured at the host system powe r 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.

2.8.3 Voltage tolerance

Voltage tolerance (including noise):
5V ± 5%

12V ± 10%

2.8.4 Power-management modes

The drive provides programmable power management to pr ovide greater energy efficiency. In most systems,
you 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.

18 Barracuda ES Serial ATA Product Manual, Rev. B

• 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 reinitializ ed 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.

Radio and television interference. This equipment generates and uses radio frequency energy and if not
installed and used in strict accordanc e 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,
you 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.

2.14 Environmental protection

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

24 Barracuda ES Serial ATA Product Manual, Rev. B

2.14.1 European Union Restriction of Hazardous Substances (RoHS)

The European Union Restriction of Hazardous Substances (RoHS) Directive restricts the presence of chemical
substances, including Lead (Pb), in electronic products ef fective July 2006. Alth ough am endments to the Euro
pean Union’s Restriction of Hazardous Substances (RoHS) Directive have not b een finalized, to the best of our
knowledge the disc drives documented in this publication will comply with the final RoHS Directive require
ments.

A number of parts and materials in Seagate products are procured from external suppliers. We rely on the rep­resentations of our suppliers regarding the presence of RoHS substances in these parts and materials. Our
supplier contracts require compliance with our che mical substance restrictions, and our suppliers document
their compliance with our requirements by providing material conten t declarations for all p arts and materials for
the disc drives documented in this publication. Current supplier declarations include disclosure of the inclusion
of any RoHS-regulated substance in such parts or materials.

Seagate also has internal systems in place to ensure on going compliance with the RoHS Directive and all laws
and regulations which restrict chemical content in electronic products. These systems include standard operat
ing procedures that ensure that restricted substances are not utilized in our manufacturing operations, labora­tory analytical validation testing, and an internal auditing process to ensure that all standard operating
procedures are complied with.

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 product s 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.

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 str ap , or ground yourself frequently by touching the metal

chassis of a computer that is plugged into a grounded outlet. Wea r 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 co nnector pins or the printed circuit board.

• Do not remove the factory-installed labels from the dr ive 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.

Barracuda ES Serial ATA Product Manual, Rev. B 27

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 detecte d” error, yo ur SATA­equipped motherboard or host adapter may use a chipset that does not suppor t SATA speed autonegotiation. If
you have a motherboard or host adapter that does not support autonegotiation:

• Install a jumper as shown in Figure 3 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 autonegoti ation)
or

• Install a SATA host adapter that supports autonegotiation, leave the drive jumper block set to “Normal
operation” (see Figure
the drive to a 1.5 Gbits/sec transfer rate.

3.0 Gbits per second operation

Limit data transfer rate to

1.5 Gbits per second

3 below), and connect the drive to that adapter. This option has the benefit of not limiting

3.3 Serial ATA cables and connectors

The Serial ATA 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, you can connect the drive as illustrated in Figure 4.

3.4 Drive mounting

You can mount the drive in any orientation using four screws in the side-mounting ho les or four screws in the
bottom-mounting holes. See Figure
tions 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).

4.3.3 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 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 . featur es disabled . You must have a recent BIOS or sof tware pa ckage 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
