1.1About the SATA interface
The Serial ATA (SATA) 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, SATA makes the transition from parallel ATA easy by providing legacy software support. SATA was designed to
allow you to install a SATA host adapter and SATA disk drive in your current system and expect all of your existing
applications to work as normal.
The SATA interface connects each disk drive in a point-to-point configuration with the SATA host adapter. There is no master/
slave relationship with SATA devices like there is with parallel ATA. If two drives are attached on one SATA 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.
The host adapter may, optionally, emulate a master/slave environment to host software where two devices on
Note
The SATA 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 SATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the
Shadow Register Block. All SATA devices behave like Device 0 devices. For additional information about how SATA
emulates parallel ATA, refer to the “Serial ATA International Organization: Serial ATA Revision 3.0”. The specification can be
downloaded from www.sata-io.org.
separate SATA 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 SATA environment.

2.7Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 4 on page 19.
2.7.1Power consumption
Power requirements for the drives are listed in Table 2:. 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-ms delay, then a 16sector 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 electronics
are in power-down mode..

2.7.2Conducted 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 peak-to-peak square-wave injected noise
at up to 10MHz.
• Using 5-volt power, the drive is expected to operate with a maximum of100 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.
2.7.3Voltage tolerance
Voltage tolerance (including noise):
• 5V ± 5%
• 12V ± 10%
2.7.4Power-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:
Power modesHeadsSpindleBuffer
ActiveTrackingRotatingEnabled
Idle_aID BiasedRotatingEnabled
Idle_bParkedRotatingEnabled
Idle_cParkedRotating at lower RPMEnabled
StandbyParked StoppedEnabled
SleepParkedStoppedDisabled
• 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, 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 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 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 disk access is necessary.

2.7.4.1Extended Power Conditions - PowerChoice
TM
Utilizing the load/unload architecture a programmable power management interface is provided to tailor systems for reduced
power consumption and performance requirements.
The table below lists the supported power conditions available in PowerChoice. Power conditions are ordered from highest
power consumption (and shortest recovery time) to lowest power consumption (and longest recovery time) as follows: Idle_a
power >= Idle_b power >= Idle_c power >= Standby_z power. The further you go down in the table, the more power savings
is actualized. For example, Idle_b results in greater power savings than the Idle_a power condition. Standby results in the
greatest power savings.

Each power condition has a set of current, saved and default settings. Default settings are not modifiable. Default and saved
settings persist across power-on resets. The current settings do not persist across power-on resets. At the time of manufacture,
the default, saved and current settings are in the Power Conditions log match.
PowerChoice is invoked using one of two methods
• Automatic power transitions which are triggered by expiration of individual power condition timers. These timer values may
be customized and enabled using the Extended Power Conditions (EPC) feature set using the standardized Set Features
command interface.
• Immediate host commanded power transitions may be initiated using an EPC Set Features "Go to Power Condition"
subcommand to enter any supported power condition. Legacy power commands Standby Immediate and Idle Immediate also
provide a method to directly transition the drive into supported power conditions.
PowerChoice exits power saving states under the following conditions
• Any command which requires the drive to enter the PM0: Active state (media access)
• Power on reset
PowerChoice provides the following reporting methods for tracking purposes

2.8Environmental limits
Temperature and humidity values experienced by the drive must be such that condensation does not occur on any drive part.
Altitude and atmospheric pressure specifications are referenced to a standard day at 58.7°F (14.8°C). Maximum wet bulb
temperature is 82°F (28°C).
The recommended storage period:
Note
• 1 year under controlled conditions of 34°C 90%RH or less
• 90 days in uncontrolled storage conditions
2.8.1Ambient temperature
a Operating
The drive meets the operating specifications over a 41°F to 140°F (5°C to 60°C) drive case temperature range with a
maximum temperature gradient of 36°F (20°C) per hour.
The maximum allowable drive case temperature is 60°C. See Figure 3 for HDA case temperature measurement location
The MTBF specification for the drive assumes the operating environment is designed to maintain nominal case
temperature. The rated MTBF is based upon a sustained case temperature of 104°F (40°C). Occasional excursions in
operating temperature between the rated MTBF temperature and the maximum drive operating case temperature may
occur without impact to the rated MTBF. However, continual or sustained operation at case temperatures beyond the
rated MTBF temperature will degrade the drive MTBF and reduce product reliability.
Air flow may be required to achieve consistent nominal case temperature values (see Section 3.4). To confirm that the
required cooling is provided for the electronics and HDA, place the drive in its final mechanical configuration, and
perform random write/read operations. After the temperatures stabilize, measure the case temperature of the drive.
b Non-operating
–40° to 158°F (–40° to 70°C) package ambient with a maximum gradient of 36°F (20°C) per hour. This specification

2.10Test for Prominent Discrete Tones (PDTs)
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 audibility and
to compensate for the inaudible components of sound prior to computation of tone ratios according to Annex D of the ECMA74 standards.
2.11Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in performance when
subjected to the radio frequeny (RF) environments defined in Table 4.
2.12.1Annualized Failure Rate (AFR) and Mean Time Between Failures (MTBF)
The product shall achieve an Annualized Failure Rate (AFR) of 1.1% (MTBF of 800 thousand hours) when operated at
nominal power and typical case temperatures of 40°C. Operation at temperatures outside the specifications in Section 2.8 may
increase the product AFR (decrease MTBF). AFR and MTBF are population statistics that are not relevant to individual units.
AFR and MTBF specifications are based on the following assumptions for business critical storage system environments:
•8760 power-on-hours per year.
•Operations at nominal voltages.
•Temperatures outside the specifications in Section 2.8 may reduce the product reliability.
•A workload rate below the average annualized specified limits. Operation at excessive I/O duty cycle may degrade product

2.14 Environmental protection
Seagate designs its products to meet environmental protection requirements worldwide, including regulations restricting
certain chemical substances.
2.14.1 European Union Restriction of Hazardous Substances (RoHS) Directive
The European Union Restriction of Hazardous Substances (RoHS) Directive, restricts the presence of chemical substances,
including Lead, Cadmium, Mercury, Hexavalent Chromium, PBB and PBDE, in electronic products, effective July 2006. This
drive is manufactured with components and materials that comply with the RoHS Directive.
2.14.2 China Restriction of Hazardous Substances (RoHS) Directive
This product has an Environmental Protection Use Period (EPUP) of 20 years. The following table contains
information mandated by China's "Marking Requirements for Control of Pollution Caused by Electronic
Information Products" Standard.
"O" indicates the hazardous and toxic substance content of the part (at the homogenous material level) is lower than the
threshold defined by the China RoHS MCV Standard.
"X" indicates the hazardous and toxic substance conte nt of the part (at the homogenous material level) is over the threshold
defined by the China RoHS MCV Standard.
2.15 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 pollutants and corrosive chemicals as electronic drive component reliability 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.

Beginning on the date of shipment to the customer and continuing for the period specified in your purchase contract, Seagate
warrants that each product (including components and subassemblies) that fails to function properly under normal use due to
defect in materials or workmanship or due to nonconformance to the applicable specifications will be repaired or replaced, at
Seagate’s option and at no charge to the customer, if returned by customer at customer’s expense to Seagate’s designated
facility in accordance with Seagate’s warranty procedure. Seagate will pay for transporting the repair or replacement item to
the customer. For more detailed warranty information, refer to the standard terms and conditions of purchase for Seagate
products on your purchase documentation.
The remaining warranty for a particular drive can be determined by calling Seagate Customer Service at 1-800-468-3472. You
can also determine remaining warranty using the Seagate web site (
determine remaining warranty information.
Shipping
When transporting or shipping a drive, use only a Seagate-approved container. Keep your original box. Seagate approved
containers are easily identified by the Seagate Approved Package label. Shipping a drive in a non-approved container voids the
drive warranty.
Seagate repair centers may refuse receipt of components improperly packaged or obviously damaged in transit. Contact your
authorized Seagate distributor to purchase additional boxes. Seagate recommends shipping by an air-ride carrier experienced
in handling computer equipment.
Storage
The maximum recommended storage period for the drive in a non-operational environment is 90 days. Drives should be stored
in the original unopened Seagate shipping packaging whenever possible. Once the drive is removed from the Seagate original
packaging the recommended maximum period between drive operation cycles is 30 days. During any storage period the drive
non-operational temperature, humidity, wet bulb, atmospheric conditions, shock, vibration, magnetic and electrical field
specifications should be followed.
Product repair and return information
Seagate customer service centers are the only facilities authorized to service Seagate drives. Seagate does not sanction any
third-party repair facilities. Any unauthorized repair or tampering with the factory seal voids the warranty.

3.0Configuring and Mounting the Drive
This section contains the specifications and instructions for configuring and mounting the drive.
3.1Handling 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:
• 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.
Caution
3.2Configuring the drive
Each drive on the SATA interface connects point-to-point with the SATA 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 SATA 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.
• 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.
3.3SATA cables and connectors
The SATA 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 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.

Each cable is keyed to ensure correct orientation. Seagate Terascale HDD drives support latching SATA connectors.
Seagate Terascale HDD Product Manual, Rev. B19
www.seagate.com
3.4Drive mounting
You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottommounting holes. Refer to Figure 5 for drive mounting dimensions. Follow these important mounting precautions when
mounting the drive:
• Allow a minimum clearance of 0.030 inches (0.76mm) 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 (3.81mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).
Weight: (maximum)4TB models
606g (1.33 lb)

4.0 SATA Interface
These drives use the industry-standard Serial ATA (SATA) interface that supports FIS data transfers. It supports ATA
programmed input/output (PIO) modes 0 to 4; multiword DMA modes 0 to 2, and Ultra DMA modes 0 to 6.
For detailed information about the SATA interface, refer to the “Serial ATA: High Speed Serialized AT Attachment”
specification.
4.1Hot-Plug compatibility
Seagate Terascale HDD drives incorporate connectors which enable you to hot plug these drives in accordance with the SATA
Revision 3.0 specification. This specification can be downloaded from www.serialata.org.
The drive motor must come to a complete stop (Ready to spindle stop time indicated in
Caution
Section 3.7) prior to changing the plane of operation.This time is required to insure data
integrity.

4.3.2Set Features command
This command controls the implementation of various features that 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:
02
03
Enable write cache (default).
H
Set transfer mode (based on value in Sector Count register).
H
Sector Count register values:
00
Set PIO mode to default (PIO mode 2).
H
01HSet PIO mode to default and disable IORDY (PIO mode 2).
At power-on, or after a hardware or software reset, the default values of the features are as indicated
above.

4.3.3S.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 monitor. For more information on S.M.A.R.T. commands and implementation, see the
DraftATA-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:
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.
