My new system seems nice and stable so far. But what I would like to know is can I take the HDD from my old rig and fit it in my new rig for the purposes of transferring all my files, I was going to use DVDs but it is amazing how much stuff you can accumulate over 5 years especially as the girlfriend has spent months scanning in her photos. The old HDD is running XP Pro the new HDD is running 7 Pro. Now I'm fairly sure that I've read somewhere that this shouldn't be a problem but I would just like to confirm I'm correct in my thinking before I carry out the changes.
