the tracks on a floppy disk. The following tracks are read according to the media type
in the floppy disk drive:
Double-sided, double-density (2D): Track 0 to 39.
Double-sided, double-density, double-track (2DD) and Double-sided, high-
density, double-track (2HD): Track 0 to 79.
The start track is specified when the Floppy Disk Drive Test is selected from the
DIAGNOSTIC TEST MENU. Refer to step 3 at the beginning of this section to set the
start track.
