Non-destructive Surface Analysis
The Nondestructive surface analysis is slightly simpler than the Destructive
surface analysis described in the previous section. This option does not
destroy any data, and can safely be used to check the condition of your hard
disk drives. However, this test will not flag any bad tracks that are detected.
To start the test, press 4 and then
Enter. You see
these messages:
Analyze Hard Disk
Read/Verify check for all tracks...
Current cylinder is xxxx
As each track is checked, the current cylinder is displayed. The cylinder
number counts down to zero as the disk is checked.
When the analysis is complete, the program displays a summary of the status
of the disk. This summary lists these counts:
l
Flagged bad tracks
l
Tracks with read, verify errors
l Good tracks.
If no errors occur, you see this message:
No read, verify error was detected.
If errors are found, the program displays a table of the tracks that gave
errors, similar to the one displayed by the destructive analysis.
After the status reports you see this message:
Press ENTER to return to the menu.
Check the information displayed, then press
Enter.
