Partition Magic 8.0 won't work with Vista, XP was the last.
I have used Norton Save & Restore and Norton Ghost 15.5 which do a good job of backing up a complete hard disk. I'm not keen on Norton 360 which budles anti-virus and backup together with anti-spy ware etc.
Windows7 (and I believe Vista) have a Disk Management facility that may do the partition job for you. Suggest you put this in the computer forum where I've always had great results.
