Hi there Dr Black,
Got the Sentinel. Although I went through the AU resources, I didn't realise that the Sentinel was tucked away in a group of other items. Anyway, he is now firmly in my computor and have already skinned him in ice. Looks great, just what I wanted. Once again, many thanks for your help.
The old hard drive will never spin again. Have stripped it down to get the magnets out - they are POWERFULL - you have to try them to believe it. I think they must be Neodymium alloy - nothing else has such strength. Good fun to play with, if you have time. If I can help you anytime you are welcome.

David
