Floppy Disk Drives and Controller Check
Use this option to test the performance of the floppy disk
(diskette) drives inside or connected to your computer. This
test includes several checks that allow you to identify particular
problems related to your diskette drives.
To run these tests, you need a formatted diskette so the
tests can write data on the disk in the drive. In a 720KB drive,
you can use only a 720KB floppy disk. In a 360KB drive, use
only a 360KB diskette. If you need to format a diskette, you
can do it without leaving the diagnostics program; see
“Formatting a diskette” below. If you already have a formatted
diskette, go on to “Starting the floppy disk drive check.”
Formatting a diskette
To format a diskette without leaving diagnostics, follow
these steps:
1. From the DEVICE LIST menu, press 0 to exit. The
OPERATION MENU appears on the screen.
2. Press 2 and Enter to select Format diskette. If you have
two diskette drives, you see this message and prompt:
Format
Diskette
Format in which
drive (A/B)?
Press A or B and Enter. If you select A, this prompt is
displayed:
Insert new diskette for drive A:
and strike ENTER when ready
3. If you have only one diskette drive, remove the reference
diskette from drive A.
4. Insert the diskette to be formatted in the drive you selected
and press Enter. The screen displays the head and cylinder
numbers as the diskette is formatted.
