However, as a last resort I would have a pc that I did not care about handy and use it to install your drive into to try and save the files. Or I would use a program called LapLink to connect the two together and transfer them.
But at this point you gotta take what you can get.
Nice repair shop you got there. You can't even hook the drive up as a secondary drive on another WinXP machine with an up-to-date virus software??? Where is that shop, I want to recommend it to all my friends...
