so I have a mac which I have files on. I put in a GUID formatted usb stick and dropped some files on to it. took the stick and plugged in to my netbook with win7. In Devices & Printers it shows up. It also appears in "safely remove hardware". no actual letter or device when i search for it in other ways. Question - how do I access the files of my GUID usb stick on my windows 7 netbook? thanks
