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 =
Count of good tracks
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 to return to
the Hard Disk Format Menu.
