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 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 nsition fr om P a rall el 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 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 cont ai ns a set of registe rs that sha dow the conte nt s of the trad iti onal 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.

2.6 Seek time
Seek measurem ent s a re t ake n wi th nom inal po w er a t 25 °C amb ient temperature. All tim es a re m easu red 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 5,000 measurements of seeks between
random tracks, less overhead.
T yp ical seek times (msec) Read Write
Track-to-track <0.8 <1.0
Average <11.0 <12.0
Average latency: 4.16 4.16
Note. These drives ar e de si gned to consisten tl y me et t he se ek t imes r epr esente d in thi s manu al. P hysical
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.

2.8 Power specifications
The drive recei ve s D C po we r ( +5V or +12V ) t hrou gh a native SATA power connector. See Fi gu re 4 on p age 26.
2.8.1 Power consumption
Power requiremen ts fo r the drive s are listed i n the t able on pa ge 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 operating
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.
DB35.3 Series Serial ATA Product Manual, Rev. D
15
• Operating pow er and current
Operating powe r is me asure d usi ng 40 p ercen t ran dom seeks, 4 0 per cent r ead/ wri te m ode ( 1 write for each
10 reads) and 20 percent drive idle mode.
• Idle mode power
Idle mode power is measu red with the drive up to speed, with servo e le ctron ics acti ve and with the he ads i n
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.

DB35.3 Series Serial ATA Product Manual, Rev. D
Figure 2. Typical 12V startup and operation current profile
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 oper ate wi th a maxim um of 120 mV peak-to -pea k 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-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:
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.
DB35.3 Series Serial ATA Product Manual, Rev. D
17
• 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 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 disc access is necessary.

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 , nicke l and gold films used i n Seag ate pr oduct s are especi ally sen s itive to the p resen ce of sulf ide, 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 am bient rel at ive hum idity gr eate r th an 9 5%. Mat erial s used in cabin et fa bri cation , 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 pr ecautions
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 plugg ed into a grounded outlet. Wear a grounded wrist strap through out 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.

DB35.3 Series Serial ATA Product Manual, Rev. D
3.2 Configuring the drive
S
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 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 otiation . 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 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” (se e Figure 3 below), and connect the drive to that adapter. Thi s option has the benefit of not l imiting
the drive to a 1.5 Gbits/sec transfer rate.

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 8
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
(
Recommended
n
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 5 on page 27 for drive mounting dimensions. Follow these important
mounting precautions 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 ship ped wi th S. M.A.R. T. features disabled. You must have a recent BIOS or so ft ware 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
