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 operates by a complex process of
writing, reading, and verifying information on every track of
the hard disk, except for tracks that are already flagged as bad
tracks.
