I've at a 160gb drive on my Macbook. It's down to 10 gigs free, which I freed up by deleting some old stuff. I have a 500 gb Western Digital hard drive that I use for a wireless backup. I think I read somewhere that I can move my iTunes music folder onto the hard drive, yet still access it "naturally" when I play music from iTunes. I stream the music wirelessly from my computer through an Airport Express. Is this possible? If so, can someone tell me how to do it? The WD drive doesn't show up in Finder. Do I need to partition it? I'm kind of clueless about this. Would I do better to just buy a larger internal hard drive for my Mac, and restore the old info from the WD? Thanks.
