1.1 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 conne
configuration options.

• Thinner and more flexible cabling for improved enclosure airflow and ease of inst

• Scalability to higher performanc

In addition, Serial ATA makes the transition from parallel ATA easy by prov iding legacy software suppor t. Serial ATA was
d

esigned 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-p oint configura tion with the Serial ATA host adap ter. There

is no master/slave relationship with Seria l ATA devices like there is with parallel ATA. If two drives ar e 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.

e levels.

ctivity. It is not necessary to set any jumpers or other

allation.

Note. Th

The Serial ATA host adapter and drive share the function of
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 a ddi tio nal inform ation
about how Serial ATA emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 2.6”.
The specification can be downloaded from www.sata-io.org.

e 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 addr esses. A host adapter that emulates a master/slave environment
manages two sets of shadow registers. This is not a typical Serial ATA environment.

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 aver­ag

e of drives tested, under nominal conditions, using 5.0V and 12.0V input voltage at 25°C ambient temperature.

Idle mode power is measured with the drive up to speed, with

rvo electronics active and with the heads in a random

track location.

• Standby mode

During standby mode, the drive accepts commands, but the drive is n

t 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 acro

ss 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 expe

cted to operate with a maximum of 100 mV peak-to-peak square-wave injected

noise at up to 10 MHz.

Note. Eq

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

2.6.3 Voltage tolerance

Voltage tolerance (including noise):
5V +1

0% / -10%

12V +10% / -10%

2.6.4 Power management modes

The drive provides programmab le power management to provide gr

eater 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

ive mode

• Act

The drive is in active mode during th

e 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

• S

tandby mode

.

The drive enters standby mode when the host sends a standby Immediate command. If the host has set the standby

er, the drive can also enter standby mode automatically after the drive has been inactive for a specifiable length of

tim
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-

bled, the heads are parked and the spindle is at rest. The drive leaves sleep mode after it receives a hard reset or soft

a
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.

2.8 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. F

or 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)

2.8.1 Test for Prominent Discrete Tones (PDTs)

Seagate follows the ECMA-74 standards for measurement and identification o

f PDTs. An exception to this process is the
use of the absolute threshold of hearing. Se agate uses th is threshold curve (origi nated in ISO 3 89-7) to d iscern 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.

2.13 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 pollut ant s and corrosive chemicals as electronic drive component reliab il­ity 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.

3.2 Configuring the drive

Power cable

Signal cable

Signal connector

Power connector

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 r eceive a “d rive not detected” error, your SATA-equipped motherboard or
host adapter may use a chipset that does not support SATA speed autonegotiation. If you have a motherboard or host
adapter that does not support 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 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 dire ctly into the host recept acle. The drive an d 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.

Figure 1. Attaching SATA cabling

Each cable is keyed to ensure correct orientation. Barracuda XT Series SATA drives support latching SATA connectors.

You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom­mounting holes. See Figure 2 for drive mounting dimensions. Follow these important mounting precautions when mount­ing the drive:

• Allow a minimum clearance of 0.030 inches (0.7

• 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).

4.3.2 Set Features command

This command controls the implementation of various features tha

t 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:

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 m onit or. 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:

http://seatools.sea

gate.com.

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.
