Option 3, Non-destructive Surface Analysis

The Nondestructive surface analysis does not destroy any data, and you can use it to safely check the condition of your hard disk drive. However, this test does not flag any bad tracks it detects.

To start the test, select Non-destructive surface analysis from the Hard Disk Format Menu. You see these messages:

Analyze Hard Disk <Drive n:>Read/Verify 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, such as the following:

Analysis finished.

Count

of

tracks flagged bad

=

n

Count of tracks with read, verify

errors =

II

Count

of

good tracks

=UU3ll

No read, verify error was detected.

If the program finds errors, the screen displays a table of the tracks that produced the errors. Then you see this message:

Press ENTER to return to the menu.

Check the information displayed. Then press m to return to the Hard Disk Format Menu.
