Option 3, Non-destructive Surface Analysis
The Non-destructive 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 bad tracks.
To start the test, select Non-destructive surf ace
analysis from the Hard Disk Format Menu. You see these
messages:
Analyze Hard
Disk
R e a d / V e r i f y c h e c k f o r a l l t r a c k s . . .
Current cylinder is
nnnn
As the program checks each track, it counts the cylinder
numbers down to zero. When the test is complete, the program
displays a status report, such as the following:
Analysis finished.

If the program finds tracks with errors, the screen displays a
table listing them. Then you see this message:
