Norton Ghost 15 stuck at 94% on onetime back up and copy HDD

I have Ghost 15 and cannot get it to complete a onetime back up or a copy (Cloning) of my hard drive.  Running XP. And copying from a 160 GB drive to a 1 TB drive.  I have run check disk and defrag several time with no luck.  Every time it gets stuck at 94% with something like 6 second remaining.  If it let it go it will come up with an error after several hours, even though it say 6 second remaining.  Any suggestions?
