Caution: This performs a destructive analysis of the hard disk media (all data
on the hard disk will be erased).
Any bad tracks found during the analysis are automatically added to the bad track table.
As bad tracks are found, they are reformatted as bad so that a subsequent MS-DOS
FORMAT operation does not attempt to use these areas on the disk.
Formatting a New Hard Disk Drive
After installing a new hard disk drive, you should enter the bad track information
provided by the manufacturer into the bad track table (see above). After this is done, press
the F7 key. This option is specifically for formatting a hard disk drive which was
previously unformatted; it performs the following operations.
q Each track of the hard disk is reformatted using the current interleave
value.
q Each track in the bad track table is reformatted as bad so that it cannot
be used.
When the format operation is complete, run a surface analysis to verify that no additional
bad tracks are found.
Formatting an Already Formatted Hard Disk
If your hard disk was previously formatted, you can press the F8 key to automatically
format preformatted drives. This causes the following operations.
q The program scans the drive for tracks that have already been marked as
bad and adds them to the bad track table.
