Seagate BarraCuda Product Manual, Rev. D 5

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.

ST8000DM004 ST6000DM003 ST4000DM004 ST3000DM007 ST2000DM005

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 20.

2.7.1 Power consumption

Power requirements for the drives are listed in Table 3 and Table 4. 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 6.

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

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.

www.seagate.com Configuring and Mounting the Drive

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 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, users can connect the drive as illustrated in Figure 1.

Figure 1 Attaching SATA cabling

Each cable is keyed to ensure correct orientation. BarraCuda drives support latching SATA connectors.

Seagate BarraCuda Product Manual, Rev. D 21

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).

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

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 8 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.

4.3.1 Identify Device command

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 on page 24. 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.

The following commands contain drive-specific features that may not be included in the SATA specification.

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:

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 12 S.M.A.R.T. commands

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.
