ABSTRACT:
A disk drive is disclosed that is responsive to standard disk-drive commands associated with disk-drive operations and to nonstandard disk-drive commands required for disk drive manufacture and quality testing. The disk drive includes a disk, a head actuated radially over the disk, and a disk control system. The disk control system responds to disk-drive commands and accesses data storage locations on the disk through the head. A serial ATA interface couples the disk control system to a host computer. The serial ATA interface is configured to transfer standard disk-drive commands from the host computer to the disk control system and is configured to not transfer nonstandard disk-drive commands from the host computer to the disk control system. The extracting means extracts a nonstandard disk-drive command that is embedded within a data block accessed using a standard disk-drive command and provides the extracted nonstandard disk-drive command to the disk control system.
