Note: This test destroys all data on the innermost cylinder of the selected hard disk drive. This cylinder is reserved for diagnostics, and is never used for storage by MS-DOS. Therefore, data created by MS-DOS is not destroyed.

Select option 2 from the menu to start this test. You see these messages:

The data on the highest physical cylinder may be destroyed by this check.

Enter Y to start this check.

Enter N to return to the menu.

Press Y and then Enter to continue with the test.

You do not see a cylinder count during the test. If no errors occur, the program returns to the menu.

If an error is reported, make a note of the code and message. Then use the Non-destructive surface analysis (option 4 on the HARD DISK FORMAT MENU) to check the condition of the hard disk. If this analysis shows no other problems with the disk, follow these steps:

1.Back up all the files on your hard disk.

2.Re-format the disk using option 2, Format hard disk, on the

OPERATION MENU.

3.Re-create the MS-DOS partition with FDISK and format it with SELECT. (See your MS-DOS manual.)

4.Restore your files.
