Test and repair your hard disk

The error check in Windows explorer revealed a few bad sectors. Now what?  The first thing to do is to backup the entire computer on a new and error free hard drive. All important data should also be copied on a DVD Rom or other storage media.

The disk may still be useable. The best way to test and possibly fix errors on the disk is by running an open source program called TestDisk 6.14. I used it to test and correct the partitions on my hard drive. I am sure that there are other comparable programs out there and you should feel free to use them.
