Barracuda SATA Product Manual, Rev.
1.0 Introduction This manual describes the functional, mechanical and interface specifications for the following Seagate Barracuda® model drives: ST31000524AS ST3500413AS ST3250312AS ST3750525AS ST3320413AS ST3160316AS These drives provide the following key features: • 7200 RPM spindle speed. • High instantaneous (burst) data-transfer rates (up to 600MB per second). • Perpendicular recording technology provides the drives with increased areal density.
Introduction www.seagate.com The Serial ATA 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 Serial ATA host adapter contains a set of registers that shadow the contents of the traditional device registers, referred to as the Shadow Register Block.
2.0 Drive Specifications 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: ST31000524AS ST3500413AS ST3250312AS ST3750525AS ST3320413AS ST3160316AS 2.1 Specification summary tables The specifications listed in the following tables are for quick reference.

4.0 Serial ATA (SATA) Interface These drives use the industry-standard Serial ATA 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 Serial ATA interface, refer to the “Serial ATA: High Speed Serialized AT Attachment” specification. 4.

www.seagate.com Serial ATA (SATA) Interface 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 32. 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.

www.seagate.com Serial ATA (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. Power-on default has the read look-ahead and write caching features enabled.
Serial ATA (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. predictability is limited to the attributes the drive can monitor.
