After the high-level formatting has been completed, the drive capacity can be verified using the DOS CHKDSK utility. ST9144 Family Installation Guide, Rev. 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. Based on the drive type, some system BIOSes look for 7 bytes of ECC. 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. The drive does not use +12 Volts DC power. 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. Pin 20 has been removed on the connector for keying purposes. A dual-drive system requires a 44-pin AT interface daisy-chain cable. Most cables have a stripe down one side to designate Pin 1. 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. [. . . ] Always power down the system before changing jumper settings or unplugging cables and cards. Check the documentation for the host adapter and the drive to confirm that these components are appropriately matched for each other and to your system. Refer to the drive and controller installation guides to make sure all jumper settings suit your configuration requirements. Make sure all cables are securely connected. [. . . ]
