Note
Be sure to insert a blank diskette that has been formatted
using the MS-DOS FORMAT command before you run the
Diskette format test. Then use that diskette when you run
any of the other destructive tests. Check that you have
inserted the correct diskette before you enter Y at the
Proceed
prompt.
You see the following prompt before the program performs a
test:
Diskette drive (A/B) ?
If necessary, type the drive identifier and press
Enter.
(If you
have only one diskette drive, drive A is already entered for
you.) Press Y and
Enter
at the Proceed
prompt to begin the
test. mess N and
Enter
to return to submenu.
Note
When you are finished running any of these tests on the
test diskette, you must reformat it using the MS-DOS
FORMAT command before you can use it with MS-DOS.

while testing a diskette drive: messages the program generates
and those the controller generates.
The program may display the following error message during
the Disk change line test:
Warning -Change line inoperational
This message appears if the line is not working properly and
may indicate a problem in the drive or its controller.
