Thanks for all your responses - you have confirmed my worst fears! Adam - yes, the first thing I did was to plug the HD into another PC. The bios check showed it's parameters (size etc) to be zero. Also, the HD could not be auto-detected at start-up. I repeated this test on several other PC's so it really does look like the HD is gone! Claudio - I've done an extensive search on the net for an identical drive. My drive was just short of three years old and I didn't come up with too many leads..... The only place I found was computergeeks.com and by the time I got around to ordering, they had none left. If you have any links I have no problems with ordering from Europe! I figured that the combined hoarding power of the list might be a good last resort :-) Spehro, Kyrre, Amaury and all who suggested a professional data recovery service - yes this is probably what I will have to do, but I figured if I could get an identical drive cheaply then it would not be a huge waste of my time to try and swap controller boards. Mike - thanks for both the offer and the advice! I'll mail you offlist about it. Thanks Alan -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
