Ok so sometimes I like to watch HD movies on my Xbox from my external usb hard drive that is formatted HFS+. I heard that formatting with Snow Leopard frees up that extra bit of HD space so I thought i'd try it. Well it sure did free up the space - after the erase/reformat there was 249.4 GB out of 250 GB (normally after a reformat there's only 232 GB out of 250 GB). So I go to plug the usb hard drive in my xbox 360 and it didn't recognize it. WTF? So then I tried to reformat it back to HFS+ with Macdrive on Windows but it still isn't recognized by the xbox. Can anyone help me out?
