ABSTRACT:
A disk drive and method are disclosed for data transfer initiated by nonstandard disk-drive commands on a serial interface that only supports standard disk-drive commands. In the method, a nonstandard disk-drive command for data transfer is embedded within a first data block accessible using a first standard disk-drive command. The first standard disk-drive command is transmitted through the serial interface causing the first data block to be transferred from the host computer to the disk control system. The embedded command is extracted from the transferred first data block and provided to the disk control system. A status response is transmitted to the host computer based on the extracted command. At least one additional standard disk-drive command is transmitted through the serial interface to the disk control system for transferring the identified data between the host computer and the disk drive.
