Before it performs any checks, the program determines the
number of diskette drives installed in your computer. If you
have more than one drive, you see this prompt each time you
select a test:
Select 1 (for drive A) or 2 (for drive B). If any errors occur,
record the error code and message and contact your dealer.
Always have the diskette drive serviced by your dealer or service
center.
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 39 for 360KB diskettes and track 79 for 1.2MB, 720KB,
and 1.44MB diskettes.
