Floppy Disk Drives and Controller Check
Use this option to test the performance of the floppy disk drives installed
in your computer. This test includes several checks that allow you to identify
particular problems related to your floppy disk drives.
Before running these tests, format a floppy disk to use for the tests that
write data on the disk in the drive. In a 360KB drive, you can only use a
360KB floppy disk. In a 720KB drive, use only a 720KB diskette.
You can select the individual tests from this menu:
