Seagate BarraCuda Product Manual, Rev. A 6
1.0 Introduction
This manual describes the functional, mechanical and interface specifications for the following
Seagate® BarraCuda® model drives:
These drives provide the following key features:
•Compliant with RoHS requirements in China and Europe.
•High instantaneous (burst) data-transfer rates (up to 600MB per second).
•Native Command Queuing with command ordering to increase performance in demanding applications.
•Quiet operation.
•SeaTools diagnostic software performs a drive self-test that eliminates unnecessary drive returns.
•State-of-the-art cache and on-the-fly error-correction algorithms.
•Support for S.M.A.R.T. drive monitoring and reporting.
•Supports latching SATA cables and connectors.
•TGMR recording technology provides the drives with increased areal density.
•Worldwide Name (WWN) capability uniquely identifies the drive.
1.1 About 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 users to install a SATA host adapter and SATA disk drive in the current system and expect all of the 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 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.
ST2000DM008
Note
The host adapter may, optionally, emulate a master/slave environment to host software where two
devices on 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.

2.7 Power specifications
The drive receives DC power (+5V or +12V) through a native SATA power connector. Refer to Figure 1 on page 19.
2.7.1 Power 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. These power
measurements are done with DIPM enabled.
• Spinup current is measured from the time of power-on to the time that the drive spindle reaches operating
speed.
• Read/Write current is measured with the heads on track, based on three 64 sector read or write operations
every 100 ms.
• The drive supports three idle modes: Performance Idle mode, Active Idle mode and Low Power Idle mode.
Refer to Section 2.7.4 for power-management modes.
2.7.2 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 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 of 100 mV peak-to-peak square-wave injected
noise at up to 10MHz.

2.7.4 Power-management modes
The drive provides programmable power management to provide greater energy efficiency. In most systems, users can
control power management through the system setup program. The drive features the following power-management
modes:
•Active mode
The drive is in Active mode during the read/write and seek operations.
• Idle mode
The electronics remain powered, and the drive accepts all commands and returns to Active mode when disk
access is necessary.
•Standby mode
The drive enters Standby mode immediately when the host sends a Standby Immediate command. If the
host has set the standby timer, the drive enters Standby mode automatically after the drive has been inac-
tive for a specifiable length of time. The standby timer delay is established using a Standby or Idle com-
mand. In Standby mode, the electronics are in low power mode, the heads are parked and the spindle is at
rest. The drive accepts all commands and returns to Active mode when disk access is necessary.
• Sleep mode
The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the electronics
are in low power mode, 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.
• 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.

2.9 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.
*During periods of drive idle, some offline activity may occur according to the S.M.A.R.T. specification, which may increase acoustic and power to
operational levels.
2.9.1 Test 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 ECMA-74 standards.
2.10 Electromagnetic immunity
When properly installed in a representative host system, the drive operates without errors or degradation in performance
when subjected to the radio frequency (RF) environments defined in Table 4.
Note
For 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

atmospheric conditions, shock, vibration, magnetic and electrical field specifications should be followed.
2.11.2 Data loss under power interruption with write cache enabled
Drive preserves its data during all operations except in cases where power to the drive is interrupted during write
operations. This could result in either an uncorrected data error being reported, or the entire sector/track becoming
unreadable. This can be permanently recovered by rewriting to the same location on the drive. Additionally any data
present in the DRAM buffer will not be written to the disk media, additionally, the drive will not be able to return the
original data.
In order to prevent this data loss, the host should issue a standby immediate or flush cache command before a controlled
power off operation to the drive.

(Name and Content of the Hazardous Substances in Product)
2.16 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.

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 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:
Caution
• Before handling the drive, put on a grounded wrist strap, or ground oneself 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 users 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.
3.2 Configuring 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.
SATA drives are designed for easy installation. It is usually not necessary to set any jumpers on the drive for proper
operation; however, if users connect the drive and receive a “drive not detected” error, the SATA-equipped motherboard or
host adapter may use a chipset that does not support SATA speed autonegotiation.
3.3 SATA 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 6 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, users can connect the drive as illustrated in Figure 1.
Figure 1 Attaching SATA cabling
Each cable is keyed to ensure correct orientation. Seagate BarraCuda drives support latching SATA connectors.
Seagate BarraCuda Product Manual, Rev. A 20
3.4 Drive mounting
Users can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-
mounting holes. Refer to Figure 2 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 (3.81 mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 6 inch-lb).
Figure 2 Mounting dimensions (1-disk models)

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.
4.1 Hot-Plug compatibility
Seagate BarraCuda drives incorporate connectors which enable users to hot plug these drives in accordance with the SATA
Revision 3.2 specification. This specification can be downloaded from www.serialata.org.
4.2 SATA device plug connector pin definitions
Table 6 summarizes the signals on the SATA interface and power connectors.
Notes
1. All pins are in a single row, with a 1.27 mm (0.050 in) 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 back-
plane configuration.
• All used voltage pins (Vx) must be terminated.

4.3.2 Set 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:
Table 9 Set Features command
02HEnable write cache (default)
03HSet transfer mode (based on value in Sector Count register)
Sector Count register values:
00HSet PIO mode to default (PIO mode 2)

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 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 shipped with S.M.A.R.T. features disabled. Users 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.
Table 10 S.M.A.R.T. commands
Code in features register S.M.A.R.T. command
D0HS.M.A.R.T. Read Data
D1HS.M.A.R.T. Read Attribute Threshold
D2HS.M.A.R.T. Enable/Disable Attribute Autosave
D3HS.M.A.R.T. Save Attribute Values
D4HS.M.A.R.T. Execute Off-line Immediate (runs DST)
D5HS.M.A.R.T. Read Log Sector
D6HS.M.A.R.T. Write Log Sector
D8HS.M.A.R.T. Enable Operations
D9HS.M.A.R.T. Disable Operations
DAHS.M.A.R.T. Return Status
Note If an appropriate code is not written to the Features Register, the
command is aborted and 0x04 (abort) is written to the Error register.
