Option 2, Destructive Surface Analysis
You can perform a destructive surface analysis of your hard disk to accurately locate any bad
tracks and flag them, if they are not flagged. The test writes, reads, and verifies information
on every track of the hard disk, except for tracks that are already flagged as bad.
To start this test, select Destructive surface analysis from the Hard Disk
Format Menu. You see these messages:
Analyze Hard Disk <Drive n:>
Read/Save/Write/Read/Restore/Read check for all tracks...
Current cylinder is nnnn
As the program checks each track, it decreases the cylinder numbers to zero.
When the test is complete, the program displays a report on the status of the disk, including a
table of unflagged tracks that produced write, read errors-such as the following:
Press Enter to return to the Hard Disk Format Menu.
If the program finds an uflagged bad track, the report is followed by a table like this:
Write, Read Error Tracks
Cylinder Head Cylinder Head Cylinder Head Cylinder Head
237 2
Confirm to register the tracks in the Write, Read Error Track
Table as bad tracks.
Do you want to register the error tracks as bad tracks? (Y/N)
To flag these tracks as bad, select Y. You see a list of the tracks as they are flagged. When
the process is complete, press Enter to return to the Hard Disk Format Menu.
