1.1About 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 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 tra nsi tion fr om Pa ral lel ATA easy b y pro vi ding leg acy sof t war e sup port . S erial
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 operatin g 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 cont ains a set of regi ste rs that sha dow the conte nt s of t he trad itional device r egisters, 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: High Speed Serialized
AT Attachment” specification. The specification can be downloaded from www.serialata.org.

2.1.7Power specifications
The drive receives DC power (+5V or +12V) through a four-pin standard drive power connector.
2.1.7.1Power consumption
Power requiremen ts for the dr iv es are listed i n the ta ble on p age 8. Typical power measurements are ba sed 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 re aches operating speed.
• Seek mode
During seek mod e, the read /write actuator arm move s toward a spe cific positi on on the d isc surface and does
not execute a read or write operation. Servo electronics are active. Seek mode power represents the worstcase 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.
• 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 powe r
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.

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 oper ate wi th a maxim um of 120 mV peak-to -pea k square- w ave
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.

2.1.7.4Power-manag ement mo des
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:
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 Immediat e c omma nd. If the ho st 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 tim er delay is established using a Standby or Idle command. In Sta ndby
mode, thedrive 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 enter s S leep m ode after rece iv ing a Slee p com man d fro m th e ho st. In Sl eep mod e, th e dr ive 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 So ft Reset from the host. After re ceiving a reset , the drive exi ts Sleep mode and en ters 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 dela y times to zero. If the standby tim er reaches zero bef ore 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.

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- inst al led labels fr om the driv e or cover the m wi th additio nal labels. R emoval voids
the warranty. Some factory-installed labels contain information needed to service the drive. Other labels are
used to seal out dirt and contamination.

3.4How to configure and attach Serial ATA (SATA) drives
S
3.4.1How to configure 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 operatin g 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 SATAequipped mother boar d or hos t ada pter may use a chipse t tha t do es no t supp ort SATA spee d au toneg oti ation . If
you have a motherboard or host adapter that does not support autonegotiation:
• Install a jumper as shown in Figure 5 below to limit the data transfer rate to 1.5 Gbits per second (and leave
the drive conne cted to the SATA-e quipped mo therboard or host a dapter tha t doesn’ t support autonegotiat ion)
or
• Install a SATA host adapter that supports autonegotiation, leave the drive jumper block set to “Normal
operation” (see Fi gure 5 below), and connect the drive to that adapter. T his option has the benefit of not l imiting

3.4.2How to connect the SATA cables
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 AW G 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.
For installations which require cables, you can connect the drive as illustrated in Figure 6.

3.5.1.2How to use the cable-select option
Computers that use cable select determine the master and slave drives by selecting or deselecting pin 28,
CSEL, on the interface bus. Master and slave drives are determined by their physical position on the cable. To
enable cable select, set a jumper on pins 5 and 6 as shown in Figure 7. Refer to your computer manual to
determine whether your computer supports this option.

3.5.1.3Ultra A TA/100 cable
An 80-conductor 40-pin cable is required to run Ultra DMA mode 3, mode 4, and mode 5. This cable uses
even-numbered conductors connected to the ground pins to improve signal integrity.
Note.
If you are using a 40-pin, 80-conductor
cable, attach the blue connector to the
motherboard, the black connector to the
master drive, and the gray connector
to the slave.

4.6S.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-7 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 ship ped w ith S. M.A.R .T. features disab led. You must have a recent BI OS or so ft wa re 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
drive uses.
Note.If an appropriate code is not written to the Features Register, the command is aborted and 0x 04
(abort) is written to the Error register.
