I just got my Samsung Free Agent Go 160 Gb for $50 free shipping (http://www.newegg.com/Product/Product.aspx?Item=N82E16822148403) but I just formatted it as Mac OSX Extended (Journal) is that right? It was originall for windows I want to use it as a backup. I have a question now, can I use timemachine and use it as a back up and then keep it for when I exchange my 13 inch macbook for a 13 inch macbook pro and just use the time machine on the macbook pro to just copy everything over?
