Oh, one thing to add. Make sure you set up the new disc with the appropriate file system (FAT32 or NTFS). Which you choose depends on your current setup. Safest thing to do is just use what you're currently using. I had a terrible problem a long time ago where I ended up losing a bunch of files because of this -- the details are too complicated to explain right now, but if I had just set up the file system the same as the other drive, everything woulda been fine.
