Non-destructive Surface Analysis

The Non-destructive 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 does not flag
any bad tracks that are detected.
To start the test, press 4 and then
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.
