Seagate BarraCuda Product Manual, Rev. L 5

1.0 Introduction

This manual describes the functional, mechanical and interface specifications for the following
Seagate® BarraCuda® model drives:
ST2000DM008 ST1000DM014

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.
• SeaToolsTM 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.
• 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.
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
Note (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 2 on page 16.

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 200 mV peak-to-peak sine-wave injected noise at up to
10MHz.
• Using 5-volt power, the drive is expected to operate with a maximum of 150 mV peak-to-peak sine-wave injected noise at up to
10MHz.

Note Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current.

2.7.3 Voltage tolerance

Voltage tolerance (including noise):
• 5V ±5%
• 12V ±10%

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:

Power modes Heads Spindle Electronics

Active Tracking Rotating Full Power

Idle, Performance Tracking Rotating Full Power

Idle, Active Floating Rotating Partial Power

Idle, Low Power Parked Rotating Partial Power

Standby Parked Stopped Low Power

Sleep Parked Stopped Low Power

• 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 inactive for a specifiable
length of time. The standby timer delay is established using a Standby or Idle command. In Standby mode, the elec-
tronics 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 com-
mands 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.
For seek mode tests, the drive is placed in seek mode only.
The number of seeks per second is defined by the following equation:
Note
(Number of seeks per second = 0.4 / (average latency + average access time

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.

2.11 Warranty
To determine the warranty for a specific drive, use a web browser to access the following web page:
www.seagate.com/support/warranty-and-replacements/
From this page, click on “Is my Drive under Warranty”. Users will be asked to provide the drive serial number, model number (or part
number) and country of purchase. The system will display the warranty information for the drive.

Seagate BarraCuda Product Manual, Rev. L 14

www.seagate.com

2.11.1 Storage
Maximum storage periods are 180 days within original unopened Seagate shipping package or 60 days unpackaged within the
defined non-operating limits (refer to environmental section in this manual). Storage can be extended to 1 year packaged or
unpackaged under optimal environmental conditions (25°C, <40% relative humidity non-condensing, and non-corrosive
environment). During any storage period the drive non-operational temperature, humidity, wet bulb, 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.

2.12 HDD and SSD Regulatory Compliance and Safety

For the latest regulatory and compliance information see: www.seagate.com/support/ scroll down the page and click the
Compliance, Safety and Disposal Guide link.

2.12.1 Regulatory models

The following regulatory model number represent all features and configurations within the series:

Regulatory Model Numbers: SKR005

2.13 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:.
• 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.
Caution
• Always rest the drive on a padded, antistatic surface until mounting 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 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, users can connect the drive as illustrated in Figure 2.
Figure 2 Attaching SATA cabling

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

Seagate BarraCuda Product Manual, Rev. L 16

www.seagate.com

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 3 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 0.140 inch (3.56 mm) into the bottom or side mounting holes.
• Do not overtighten the mounting screws (maximum torque: 8 inch-lbs max).

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 8 Set Features command
02H Enable write cache (default)

03H Set transfer mode (based on value in Sector Count register)

Sector Count register values:

00H Set PIO mode to default (PIO mode 2)

01H Set PIO mode to default and disable IORDY (PIO mode 2)

08H PIO mode 0

09H PIO mode 1

0AH PIO mode 2

0BH PIO mode 3

0CH PIO mode 4 (default)

20H Multiword DMA mode 0

21H Multiword DMA mode 1

22H Multiword DMA mode 2

40H Ultra DMA mode 0

41H Ultra DMA mode 1

42H Ultra DMA mode 2

43H Ultra DMA mode 3

44H Ultra DMA mode 4

45H Ultra DMA mode 5

46H Ultra DMA mode 6

06H Enable the PUIS feature set

07H PUIS feature set device spin-up

10H Enable use of SATA features

55H Disable read look-ahead (read cache) feature

82H Disable write cache

86H Disable the PUIS feature set

90H Disable use of SATA features

AAH Enable read look-ahead (read cache) feature (default)

F1H Report full capacity available

At power-on, or after a hardware or software reset, the

Note default values of the features are as indicated above.

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:
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 9 S.M.A.R.T. commands
Code in features register S.M.A.R.T. command
D0H S.M.A.R.T. Read Data

D1H S.M.A.R.T. Read Attribute Threshold

D2H S.M.A.R.T. Enable/Disable Attribute Autosave

D3H S.M.A.R.T. Save Attribute Values

D4H S.M.A.R.T. Execute Off-line Immediate (runs DST)

D5H S.M.A.R.T. Read Log Sector

D6H S.M.A.R.T. Write Log Sector

D8H S.M.A.R.T. Enable Operations

D9H S.M.A.R.T. Disable Operations

DAH S.M.A.R.T. Return Status

If an appropriate code is not written to the Features Register, the

Note command is aborted and 0x04 (abort) is written to the Error register.
