Graham & Ziggy: The program I use for backing up my HD is PowerQuest Corporation's "Drive Image 7".

Interesting to note that Symantec recently took over PowerQuest.

I suppose I could go back to the latest backup I did with Drive Image, but unfortunately that was several months ago. and I've installed several new programs etc since then. I realize now that you have to keep the backups updated regularly. Easier said then done I suppose. - Scott
