Introduction www.seagate.com 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 Note the same set of host bus addresses. A host adapter that emulates a master/slave environment manages two sets of shadow registers.
Unless otherwise noted, all specifications are measured under ambient conditions, at 25°C, and nominal power. For convenience, the phrases the drive and this drive are used throughout this manual to indicate the following drive models: ST4000DM000 ST3000DM003 2.1 Specification summary tables The specifications listed in are for quick reference.

Drive Specifications 2.6 Seek time Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using drive diagnostics. The specifications in the table below are defined as follows: • Track-to-track seek time is an average of all possible single-track seeks in both directions.
Drive Specifications www.seagate.com 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. Table 2 DC power requirements (3TB and 4TB) Power dissipation (4-disk values shown) Avg (watts 25°...
Drive Specifications • 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.
Drive Specifications www.seagate.com 2.9.4 Altitude Operating –304m to 3048m (–1000 ft. to 10,000 ft.) Non-operating –304m to 12,192m (–1000 ft. to 40,000+ ft.) The maximum storage period: Note • 90 days in uncontrolled storage conditions 2.9.5 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws.
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.
As a subassembly, no Federal Communications Commission verification or certification of the device is required. Seagate has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disk drive, motherboard, power supply, etc.) does comply with the limits for a Class B computing device, pursuant to Subpart J, Part 15 of the FCC rules.
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 Desktop HDD SATA Product Manual, Rev.

Drive Specifications www.seagate.com 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 •...

Desktop HDD drives support latching SATA connectors. 3.4 Drive mounting You can mount the drive in any orientation using four screws in the side-mounting holes or four screws in the bottom-mounting holes.
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”...

SATA Interface 4.3.1 Identify Device command The Identify Device command (command code EC ) 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 26. All reserved bits or words should be set to zero.

SATA Interface www.seagate.com GPL feature set is supported. WRITE DMA FUA EXT and WRITE MULTIPLE FUA EXT commands are supported. WRITE DMA QUEUED FUA EXT command is supported. 64-bit World Wide Name is supported. 9-10 Obsolete. 11-12 Reserved for TLC.
SATA Interface 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.
SATA Interface www.seagate.com 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.
