Hi, I just got a new Dell Dimension that came with Windows XP installed on a 80G HD. I would like to add my 40G hard drive from my old computer that has W2K as a second hard drive. Will i be able to access the old drive even though they are different OS'? I know they are based on the same tech, but didn't know if there were any problems that could potentially arise. Sorry if this question seems stupid, I have never used XP before nor had 2 hard drives set up on the same system. I plan to move over my music and video files from the old HD to the new one and then format the old one so i can take advantage of the full drive without all the programs and crap on there now. Thanks for the help!!!!
