After you have backed up your computer, you should contact your computer manufacturer or other hardware technical support to determine if the disk with errors needs to be repaired or replaced.

We recommend that you store these printed instructions together with the media used to back up your data (for example, the CDs or USB flash drive used to store your backup), so that everything you need to fix your computer is in one place.
