I had this happen not so long ago, just would not display 'D' drive and in trying to find a phone number for Microsoft, I cheekily contacted one of the comp mags and the chap who I spoke to, I mentioned why I wanted Microsoft's number. He said that he may be able to help but would entail going into the registry. I don't mind, provided I have idiot instructions. He said he would send me the instructions which he did. If you still have this problem then I can upload a copy of the information but I must bring to your attention the warnings that are in the instructions. Perhaps Ray could advice you if you require this information.
