  • Page 12: About The Serial Ata (Sata) Interface

    About the Serial ATA (SATA) 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 jump- ers or other configuration options.

  • Page 13: 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 ST910021AS, ST980825AS, ST96023AS, and ST94015AS models. Specification summary table The specifications listed in this table are for quick reference.

  • Page 19: Deferred Spinup

    Out-Of-Band (OOB) signals with a functional host-side Serial ATA port. In desktop systems, SATA transceivers should initialize OOB as soon as power comes ready to guarantee the drive spins up quickly. Seagate disc drives will not spin up without an operational host-side Serial ATA transceiver. Additional details Upon system power up, PHY communication is initiated with a COMRESET signal, which is generated by the host-side transceiver.

  • Page 20: Conducted Noise

    2.9.3 Conducted noise Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on the +5 volt line. 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.

  • Page 21: Environmental Specifications

    • 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.

  • Page 22: Shock

    2.10.5 Shock All shock specifications assume that the drive is mounted securely with the input shock applied at the drive mounting screws. Shock may be applied in the X, Y or Z axis. 2.10.5.1 Operating shock These drives comply with the performance levels specified in this document when subjected to a maximum operating shock of 250 Gs based on half-sine shock pulses of 2 msec.

  • Page 23: Acoustics

    2.11 Acoustics Drive acoustics are measured as overall A-weighted acoustic sound power levels (no pure tones). All mea- surements 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.

  • Page 24: Reliability

    Information Technology Equipment (ITE). Emission levels are defined by EN 55022, Class B and the immunity levels are defined by EN 55024. Seagate uses an independent laboratory to confirm compliance with the EC directives specified in the previous paragraph. Drives are tested in representative end-user systems. Although CE-marked Seagate drives comply with the directives when used in the test systems, we cannot guarantee that all systems will comply with the directives.

  • Page 25: Fcc Verification

    As a subassembly, no Federal Communications Commission verification or certification of the device is required. Seagate Technology LLC has tested this device in enclosures as described above to ensure that the total assembly (enclosure, disc 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.

  • Page 26: Environmental Protection

    The sil- ver, 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%.

    Configuring and mounting the drive This section contains the specifications and instructions for configuring and mounting the drive. Handling and static-discharge precautions After unpacking, and before installation, the drive may be exposed to potential handling and electrostatic dis- charge (ESD) hazards. Observe the following standard handling and static-discharge precautions: Caution: •...

  • Page 28: Configuring The Drive

    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”...

  • Page 29: Drive Mounting

    Drive mounting You can mount the drive using four screws in the side-mounting holes or four screws in the bottom-mounting holes. See Figure 4 for drive mounting dimensions. Follow these important mounting precautions when mount- ing the drive: • Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling. •...

  • Page 39: Set Features Command

    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 inter- rupt. 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.
