Subtest 01 Sequential Read
This subtest performs a Cyclic Redundancy Check (CRC), that continuously
reads all 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): 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.
