Barracuda 7200.7 Serial ATA Product Manual, Rev. C 1.0 1 Introduction This manual describes the functional, mechanical and interface specifications for the following Seagate Barracuda® 7200.
2 Barracuda 7200.7 Serial ATA Product Manual, Rev. C Figure 1. Barracuda 7200.7 Serial ATA disc drive 1.1 About the Serial ATA interface The Serial ATA 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.
Barracuda 7200.7 Serial ATA Product Manual, Rev. C 3 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.

Barracuda 7200.7 Serial ATA Product Manual, Rev. C 2.7 11 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. • Average seek time is a true statistical random average of at least 5,000 measurements of seeks between random tracks, less overhead.
12 2.9.1 Barracuda 7200.7 Serial ATA Product Manual, Rev. C Power consumption Power requirements for the drives are listed in the table on page 9. 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. • Spinup power Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.

Barracuda 7200.7 Serial ATA Product Manual, Rev. C 2.9.2 15 Deferred spinup Barracuda 7200.7 Serial ATA drives provide a deferred spinup feature which storage subsystem controllers can use to sequence disc drive initialization. This is beneficial to systems which include multiple Serial ATA hard disc drives because it allows subsystem controllers to stagger the spinup of each drive to accommodate available power supply current. This feature does not impact time-to-ready in typical desktop systems.
16 Barracuda 7200.7 Serial ATA Product Manual, Rev. C • 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 10 MHz. Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write current. 2.9.4 Voltage tolerance Voltage tolerance (including noise): 5V ± 5% 12V ± 10% 2.9.5 Power-management modes The drive provides programmable power management to provide greater energy efficiency.
Barracuda 7200.7 Serial ATA Product Manual, Rev. C 17 • Sleep mode The drive enters Sleep mode after receiving a Sleep command from the host. In Sleep mode, the drive buffer is disabled, 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 with all current translation parameters intact.

20 Barracuda 7200.7 Serial ATA Product Manual, Rev. C 2.11 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.

C 3.0 25 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.
26 3.2 Barracuda 7200.7 Serial ATA Product Manual, Rev. C Configuring the drive Each drive on the Serial ATA interface connects in a point-to-point configuration with the Serial ATA host adapter. There is no master/slave relationship because each drive is considered a master in a point-to-point relationships. If two drives are attached on one Serial ATA host adapter, the host operating system views the two devices as if they were both “masters” on two separate ports.

Barracuda 7200.7 Serial ATA Product Manual, Rev. C 4.3.2 41 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.
42 Barracuda 7200.7 Serial ATA Product Manual, Rev. C 4.3.3 S.M.A.R.T. commands S.M.A.R.T. provides near-term failure prediction for disc 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.
