karma,

In Windows XP, much like when running the onboard Chkdsk/Error Checking program, you'll need to restart the computer before "fix errors automatically" will work. The drive must be freed up in order to do a full disk check. Error Checking can be done in Windows XP, without Norton's DD, by opening "My Computer", RIGHT clicking on the C drive, choose "Properties", then in the "Error Checking" section, place a CHECK mark in both boxes. Click on OK and the computer will need to be restarted. It will automatically run the Disk Check/Error Check at that time.

Hope this helps.
