Epson Y16499100301 User Manual

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.”

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.
