Sequential seek check
This test checks the ability of the read/write heads to
locate any part of the diskette. This action by a read/write
head is called a seek. During this test, each head seeks
sequentially from the innermost track to the outermost track.
The innermost track is track 79 for 720KB diskettes and track
39 for 360KB diskettes.
Select option 1 from the menu to start this test. The
program displays the number of each track it finds, counting
down from 79 or 39 to 0.
The seek is performed by each head, so you see the count
twice. If no errors occur, the menu is displayed.
Random seek check
This test is identical to the sequential seek check, except
that the seek operation is performed on each track in random
order instead of sequential order. Select option 2 from the
menu to start this test.
Write, read check
This test checks the ability of the selected disk drive to
read and write data from a diskette. The test writes to and
reads from each cylinder on the diskette, starting at the center.
