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

A computer system comprising:

• a host computer;
• and
• a disk drive coupled to the host computer and having a host interface subsystem for processing host commands received from the host computer, the host interface subsystem, including:
• a user partition for storing data for execution by the host computer,
• a drive management partition for storing data for execution by the disk drive,
• a disk-drive-selected application partition for storing data for execution by the host computer in response to a drive-determined condition,
• a user command interface for processing first host commands directed to storing data in the user partition according to an industry standard interface protocol,
• a first drive management command interface for processing second host commands directed to storing data in the disk drive management partition according to a first disk-drive command protocol,
• a second drive management command interface for processing third host commands enabling data storage in the disk-drive-selected application partition according to a second disk-drive command protocol.
