Thank you for your prompt reply. And I am glad to hear that there won't be any compatability problems between the
Hard Drives, and the programs.
However I have run into another problem, I can't find my C drive. It's not there any more. After I downloaded the clean out program and told it to clean up C&D drives. I noticed that C drive was not recognised. After my C drive got so slow I installed Windows on an unused partion ( D drive). I then had to go out of town and I am just getting back to this problem. Anyway I heard of a program Able something that is suspossed to be able to recover lost partions. So I am going to try to track it down and look at it and see if I can use it or something else. I am also thinking about useing the computer as a boat anchor. I am already spending more time on this than I want and have to go out of town again shortly and I have to recover C drive befor I can try to fix whatever is wrong with it. I am really considering just wiping the C partion and doing a clean install. Sorry for the rant, but it is very frustrating. Again thank you for your time and trouble.
