Ok, I have a 2TB WD MyBook external hard drive it works great with my MacBook Pro that is running Leopard, but when I try to plug it into my wife's laptop that runs Windows XP, XP doesn't recognize the drive. I realize that it's technically a Windows problem, but I figured the Mac community would probably be more helpful. I'm not computer savvy at all so any help will probably have to be broken down like you are talking to a toddler. Thanks in advance!
