1.1About the Serial A TA 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 transi tio n from pa rall el ATA eas y 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 cont ai ns a set of registe rs that sha dow the conte nts of the traditional 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.

2.8Power specifications
The drive receives DC power (+5V and +12V) through a native SATA power connector. See Figure 5 on
page 19.
2.8.1Power consumption
Power requiremen ts fo r the drive s are listed i n the t able on pa ge 9. 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 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.
• Operating power and current
Operating power is measured using a standrad Consumer Storage Profile.
• 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.

2.8.2Conducted 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 operate with a maximum of 120 mV pe ak-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.
2.8.3Voltage tolerance
Voltage tolerance (including noise):
5V ± 5%
12V ± 10%
2.8.4Power-manag eme nt 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:
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 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, 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 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
10
DB35 Serial ATA Product Manual, Rev. E
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.
2.9Environmen tal specifications

2.14Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations
restricting certain chemica l subst ances .
2.14.1European Union Restriction of Hazardous Substances (RoHS)
The European U nion Restr icti on of Hazard ous S ubst ance s (RoHS ) Dire cti ve re strict s the p resen ce of ch emic al
substances, including Lead (Pb), in electronic products effective July 2006. Although amendments to the
Euro-pean Union’s Restriction of Hazardous Substances (RoHS) Directive have not been 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
rep-resentat ions o f our sup pl iers reg ardi ng the pr esence of RoHS subst ances in these p arts and mate rials. Our
supplier contracts require compliance with our chemical substance restrictions, and our suppliers document
their compliance wi th our re quire ment s by providing material conte nt declar ations for al l par ts an d mater ial s 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.
DB35 Serial ATA Product Manual, Rev. E
15
Seagate also has internal system s in place to en sure ongoing complian ce 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,
labora-tory analytical validation testing, and an internal auditing process to ensure that all standard operating
procedures are complied with.
2.15Corrosive 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 electr onic dr i ve com ponen t reliab ilit y can be af fecte d by th e i nst allationenvironment. The sil-
ver, copper, nickel and gold films used in Seagate products are especially sensitive to the presence of sulfide,
chloride, and nitr ate c ont ami na nt s. S ulfur is found to be the m ost dam aging . In ad di tion, e lectron i c comp onent s
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.

3.0Configuring and mounting the drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1Handling and static-discharg e precautio ns
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:
• Keep the drive in the electrostatic discharge (ESG) bag until you are ready for installation.
• 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.

3.2Breather f ilter hole precaution s
(
This section contain s inf ormati on reg ardin g the pre c aution s to take with th e breat her fil ter hole in Se agate ha rd
disc drives. Take the proper precautions to ensure full functionality and to prevent possible damage to the
drive.
Breather hole
Do not cover or seal
this hole.
Figure 3. Breather filter hole location
Caution: Do not cover, seal, or insert any object into this hole.
This hole has two purposes:
• To allow condensation inside the hard disc to escape
• To allow air pressure inside the hard disc to equalize with ambient pressure
Note.If this hole is covered, sealed, or penetrated by any object, drive reliability may be compromised
and could lead to permanent damage--doing so voids the warranty.
3.3Configuring the drive
Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host
adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point
relationships. 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 sep a rate ports. This means both drives b ehave as if they are
Device 0 (master) devices.
Serial ATA drives ar e des ig ned f or e asy inst al lation w ith no jump ers, terminators, or other settings. It is not necessary to set any jumpers on this drive for proper operation. The jumper block adjacent to the signal connector
is for factory use only.

3.4Serial ATA cables and connectors
S
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 5.

Notes:
1. All pins are in a single row, with a 1.27 mm (0.050”) pitch.
2. The comments on the mating sequence apply to the case of backplane blindmate connector only. In this
case, the mating sequences are:
• the ground pins P4 and P12.
• the pre-charge power pins and the other ground pins.
• the signal pins and the rest of the power pins.
3. There are three power pins for each voltage. One pin from each voltage is used for pre-charge when
installed in a blind-mate backplane configuration.
4. All used voltage pins (Vx) must be terminated.

4.3Supported ATA commands
The following table lists Serial ATA standard commands that the drive supports. For a detailed description of
the ATA commands, refer to the Serial ATA: High Speed Serialized AT Attachment specification. See
“S.M.A.R.T. commands” on page 29.for details and subcommands used in the S.M.A.R.T. implementation.
The Identify Device command (command code ECH) transfers information about the drive to the host following
power up. The data is organized as a single 512-byte block of data, whose contents are shown in Table 6 on
page 23. All reserved bits or words should be set to zero. Parameters listed with an “x” are drive-specific or
vary with the state of the drive. See Section 2.0 on page 3 for default parameter settings.
The following commands contain drive-specific features that may not be included in the Serial ATA specification.

4.3.2Set Features comman d
This command con trols the implement ation of var ious features that the dr iv e sup port s. 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

4.3.3S.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 w ith S. M.A.R .T. features disab led. You must have a recent BIOS or soft 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
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.
