Disk Change Check
This test checks the ability of the diskette drive to detect that a
diskette has been removed or inserted.
Note
Disk changes cannot be detected by 360KB 5 1/4-inch drives.
Select option 5 from the menu to start this test. You see the
following message:
DISK CHANGE CHECK
Remove the disk from drive A.
As soon as you remove the diskette, you see the following message:
Re-insert the disk into drive A.
Re-insert the diskette. If no errors occur, the menu reappears. An
error occurs if the drive is malfunctioning or if you do not remove
or replace the diskette within a certain time.

When you choose this option, all checks for the diskette drive(s)
and controller are performed automatically in sequential order.
