Hard Disk Problems

If you have a problem with a hard disk, it could be the result of

improper installation, incomplete disk preparation, or

corrupted data. Consult one of the following sections,

depending on the problem you are having:

Installing the drive

Preparing the drive for use

Accessing data on the drive.

For example, if you could use the data on your disk in the past

but suddenly cannot, see “Accessing Data on the Drive.”

If your hard disk has data on it, always be sure to back up

your data before reformatting or repartitioning the drive.
