If you choose to install a new hard drive or buy another one...your gonna have to archive you collection on cd anyway...because if you try to move files from one drive to another...two reasons: One - it will take a hell of a long time and 2 - if you have a Windows Os higher than '98, when you move the files from one drive to another the original files still move to the other drive, but they will also stay on the original drive until you decide to delete them...so if I were you...I would spend the money on Data cd's and archive my drive...it's alot easier and will only take about a 2 days to complete the entire operation...I Hope this helped
