Floppy Disk Drives and Controller Check

Use this option to test the performance of the diskette (floppy disk) 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 360KB drive, you can use only a 360KB diskette. In a 720KB drive, use only a 720KB 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 DisketteTo 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 DisketteFormat 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.
