Hey - currently have a two HDD two OS (XP Pro 32 and Win 7 Pro 64). The XP is on a HDD that is 7 years old and I am just a bit nervous. Just installed a new 500 gb hdd. Can I put XP pro 32 on this new drive and slowly migrate my files to it so when the older drive stops working I'll have all my files and programs saved? Oh just for information should I install XP Pro 32 or 64 on the new HDD?
