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.
