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.

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:

Analyze Hard DiskRead/Save/Write/Read/Restore/Read check for alltracks...

Current cylinder is xxxx

As each track is checked, the cylinder number (xxxx) counts down to zero. When the analysis is complete, the program displays a complete report on the status of the disk, including a table of unflagged tracks that produced write, read errors. For a hard disk with no unflagged bad tracks, a display like this appears:
