COMPUTER SYSTEM HAVING A HOST COMPUTER COUPLED TO A DISK DRIVE WITH A DRIVE-SELECTED-APPLICATION PARTITION FOR STORING DATA FOR EXECUTION BY THE HOST COMPUTER IN RESPONSE TO DRIVE-DETERMINED CONDITIONS

摘要

A computer system has a host computer coupled to a disk drive having a host interface subsystem. The host interface subsystem includes a user partition, a drive management partition, and a disk-drive-selected application partition. The user partition stores data for execution by the host computer. The drive management partition stores data for execution by the disk drive. The disk-drive-selected application partition stores data for execution by the host computer in response to a drive-determined condition. The host interface subsystem further includes a user command interface that processes commands for storing data in the user partition, a first drive command interface that processes commands for storing data in the disk drive management partition according to a first disk-drive command protocol, and a second drive command interface that processes commands enabling data storage in the application partition according to a second disk-drive command protocol.
