Abstract

Diskette drive determination in which a read/write head in a diskette drive is instructed to move to a track that is inaccessible on one type of diskette drive. The head is then stepped back toward a track associated with a sensor indicating the positioning of the head over the track. The number of steps required to activate the sensor determines which type of drive is being used.
