Hard Disk Diagnostics

Hard disk diagnostic tests fall into two categories: destructive

or nondestructive. Destructive diagnostics destroy data on the

hard disk, but nondestructive diagnostics do not. Be sure to

back up any data on your hard disk before performing any

destructive tests. The following table lists which tests are

destructive and which are not.
