Select option 1 from the menu to start this test. The program
displays the number of each track it finds. For example, with a
1.2MB diskette, the first message you see is:
79
The track number counts down (from 39 or 79) 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 on a diskette. The test writes to and reads from each
track on the diskette, starting at the center.
This test destroys all data on the diskette in the selected
drive.
Select option 3 from the menu to start this test.
