Hi I've just ordered a MacBook Pro with a WD Ultra external HD. I already have a Windows Vista machine with a run-of-the-mill external hard drive. On it I have MP3s, photos, and some important Word and Excel files. I want to transfer everything off it to my new WD Ultra for use on my MacBook Pro. I will never use the Windows machine again. Is it as simple as copying the files from one hard drive to another and carrying on as if nothing had happened? Many thanks.
