If you have only one floppy disk drive, you are prompted to change the

diagnostics diskette for a blank diskette before running the test. You see these

messages:

Use only a formatted blank diskette for this test.
Any data present may be erased.
If using drive A, remove your Diagnostics Disk.
Enter Y to start this check.

Enter N to return to the menu.

Make sure the blank diskette you prepared is in drive A, then press Y and

Enter.

The program displays the current track number as each cylinder is tested. For example, with a 720KB floppy disk, the first message you see is:

Current track is 79

Speedcheck

This test checks the revolution speed of the specified disk drive. Select option 4 from the menu to start this test. You see a message similar to this:

The disk rotation speed should be more than 294.0 rpm and less than 306.0 rpm.

The computer spins the diskette for a few seconds then displays a message like this:

The disk rotation speed is now 300.0 rpm.

Note: The speed for a 360KB or 720KB (3½-inch) drive should be 300 rpm. This check permits a tolerance of ± 2%.

The diskette continues to spin, and the disp1ay is updated every few seconds. To stop the test, press any key; the program returns to the menu.

If you try to perform a speed test without inserting a floppy disk, or if a
read error occurs, you see this message and prompt:
Disk is defective or not installed properly.

Press ENTER to return to the menu.

Run all above checks

To run all the tests on the menu in sequence, press 5 and then Enter.
