[. . . ] B 7 Supported system BIOS revisions These drives are AT interface compatible drives. The host system BIOS must provide full support for the AT interface command set. Consult the system documentation for implementation information for your system. In accordance with the ATA/CAM specification, after a hard reset is received from the host, the BIOS must reset any emulation/translation parameters for the drive. The ST9144 family AT interface drives use 4 bytes of Error Correction Code (ECC) with the Read Long/Write Long commands. If your system expects 7 bytes of ECC, some drive diagnostic programs return false failures (typically time-out errors). Consult your system documentation, or call your system dealer or manufacturer for information on configuring your system to receive 4 bytes of ECC. 8 ST9144 Family Installation Guide, Rev.

The ST91 44 family driv es u se +5 Volts DC power supplied to the drive through the interface connector. Refer to the "44-Pin AT Interface Connector Assignment" table for specific pin assignments. Make sure only +5 Volts DC is being supplied to the drive, as specified in the "44-Pin AT Interface Connector Assignment" table. Use a 44-pin AT interface connector cable with two rows of 22 female contacts on 0. 079 inch (2 mm) centers. Make sure Pin 1 on the interface cable connector is aligned to Pin 1 on the drive interface connector and Pin 1 on the host connector. The maximum cable length is 18 inches (457 mm). ST9144 Family Installation Guide, Rev. /PDIAG and /DASP are used for communication between master and slave drives. 12 ST9144 Family Installation Guide, Rev. B Power management mode descriptions The ST9144 family drives feature four-phase power management with Active, Idle, Standby and Sleep modes. Power management is required for low-power portable systems, and is enabled through a system-dependent set-up procedure. Consult your system documentation for power management information. ST9051A power management mode descriptions Active mode. The drive is in Active mode during the read/write and seek operations. At power-on the drive defaults to Idle mode after 5 seconds of inactivity. The heads are parked and latched away from the data zones for maximum data integrity. [. . . ] Screw insertion depth is limited to 0. 150 inches (3. 81 mm) maximum on the side mounting holes and 0. 190 inches (4. 82 mm) maximum on the bottom mounting holes. ST9051A drive with part number 914003-XXX has standard screw thread size: 4-40 UNC-2B. Screw insertion depth on the ST9052A is limited to 0. 1490 inches (3. 80 mm) maximum on the side and bottom mounting holes.
