1.1
About the Serial ATA interface
The Serial ATA interface provides several advantages over the traditional (parallel) ATA interface. The primary advan-
tages 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 ATA easy by providing legacy software support. Serial ATA was
designed to allow you to install a Serial ATA host adapter and Serial ATA disk drive in your current system and expect all
of your existing applications to work as normal.
The Serial ATA interface connects each disk 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 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 “Serial ATA International Organization: Serial ATA Revision 2.6”.

Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. See Figure 1 on page 17.
2.6.1 Power consumption
Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on an aver-
age 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.
• Seek mode
During seek mode, the read/write actuator arm moves toward a specific position on the disk surface and does not exe-
cute a read or write operation. Servo electronics are active. Seek mode power represents the worst-case power con-
sumption, 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-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.

2.6.2
Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 80-ohm resistive load on the +12V
line or an equivalent 15-ohm resistive load on the +5V line.
• Using 12-V 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-V 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.

Power management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems, you can
control power management through the system setup program. The drive features the following power management
modes:

• 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.

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.
Note. For seek mode tests, the drive is placed in seek mode only. The number of seeks per second is defined by the
following equation:
(Number of seeks per second = 0.4 / (average latency + average access time)

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 audi-
bility and to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D
of the ECMA-74 standards.

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 cus-
tomer. 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 noncertified assemblies is likely to result in interference to radio and television recep-
tion.
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. How-
ever, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause interfer-
ence 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.
If necessary, you should consult your dealer or an experienced radio/television technician for additional suggestions. You
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.

Corrosive environment
Seagate electronic drive components pass accelerated corrosion testing equivalent to 10 years exposure to light indus-
trial 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 reliabil-
ity 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 damag-
ing. 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 fabrica-
tion, 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.

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.

Barracuda XT Series SATA Product Manual, Rev. C
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 detected” error, your SATA-equipped motherboard or
host adapter may use a chipset that does not support SATA speed autonegotiation.
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 5 for connector pin defi-
nitions. 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 1.

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 for drive mounting dimensions. Follow these important mounting precautions when mount-
ing 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).

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 predeter-
mined 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 unnec-
H
essary 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.
