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.
3.2 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. This means both drives behave as if they are Device 0 (master) devices.
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. See Figure 4 on page 17 for drive mounting dimensions. Follow these important mounting precautions when mounting the drive: • Allow a minimum clearance of 0.030 inches (0.76 mm) around the entire perimeter of the drive for cooling. • Use only 6-32 UNC mounting screws. • The screws should be inserted no more than 0.150 inch (3.

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 Table 5 on page 21. 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. See Section 2.0 on page 3 for default parameter settings.
Word Description Value 60–61 Total number of user-addressable LBA sectors available (see Section 2.1 for related information) *Note: The maximum value allowed in this field is: 0FFFFFFFh (268,435,455 sectors, 137 Gbytes). Drives with capacities over 137 Gbytes will have 0FFFFFFFh in this field and the actual number of useraddressable LBAs specified in words 100-103. This is required for drives that support the 48-bit addressing feature.
Word Description Value 129– 159 Seagate-reserved xxxxH 160– 254 ATA-reserved 0000H 255 Integrity word xxA5H Note. Advanced Power Management (APM) and Automatic Acoustic Management (AAM) features are not supported Note. See the bit descriptions below for words 63, 88, and 93 of the Identify Drive data. Description (if bit is set to 1) Bit Word 63 0 Multiword DMA mode 0 is supported. 1 Multiword DMA mode 1 is supported. 2 Multiword DMA mode 2 is supported.
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.
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. For more information on S.M.A.R.T.
