NIS 2006 and Save and Restore

I run Norton Internet Security 2006, along with about 8 other Norton products, on the computer I use.  I have tried using Save and Restore to do a full backup way too many times.  S & R will backup drives D, F, G, but will not backup drive C.  I get the message that the hardware is not working. (the hardware that I just backed up 800 gig to from the other drives?)  I am using WinXP and have 4 gig memory.

 

Below is a screenshot of what I get when I try to backup C drive.
