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): Tracks 0 to 39.
Double-sided, double-density, double-track (2DD), and double-sided,
high-density, double-track (2HD): Tracks 0 to 79.
The start track is specified when the FDD test is started from the Diagnostic
Test Menu. Refer to Step 3 at the beginning of this section to set the start
track.
Subtest 02 Sequential Read/Write

lected in Subtest 01. The data is then read and compared to the original data.

The data is then read and compared to the original data.
