Howdy all you tech savvy super humans! I am a new mac user and new jump driver. Here's the prob: I plug my drive in the usb and, though it says "0 items", it is full to capacity. I was told to reformat it but I am really lame at computer stuff, especially being new to the mac world. As far as I know, I tried everything. If anyone can save my life, and explain in not so genius terms, I'd be sooooooo appreciative!!!!! Thanks uber mucho!
