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 tracks.
Caution
If any errors occur during this check, all data on the track
that caused the error is destroyed. If you think that an
unflagged bad track is causing trouble, first run the
Non-destructive surface analysis to check the disk surface.
