If this analysis shows no other problems with the disk, follow these steps:

Back up all the files on your hard disk.

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

OPERATION MENU.

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

Restore your files.

Head select check

This test checks whether each head of the hard disk drive can be selected

correctly. If both heads are checked without an error, the program returns to

the menu.

Select option 3 from the menu to start this test.

Error detection and correction check

This test checks the ability of the hard disk drive to detect a read/write

error and to correct the data accordingly.

Note:

This test destroys some 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

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

the menu.

Press

and then

Enter

to continue with the test. If no errors occur, the

menu reappears.

An error occurs only if the drive is malfunctioning. In this case, back up

all your files, and have the drive serviced immediately. (The drive may be

corrupting your data.)
