Destructive Surface Analysis
Use this option to accurately locate any bad tracks on a hard disk, and to
flag any bad tracks that are not flagged.
WARNING: If any errors occur during this check, all data on the track
that produces the error is destroyed. For this reason, if you
think that an unflagged bad track is causing trouble, first
run option 4, Non-destructive surface analysis, to check
the disk surface.
This 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.
To start the test, press 3 and then Enter. You see these messages:
