Hi, I sorry to say that I am new to Macs, i got my very first Ibook 3 days ago. With it, i got a 4Gig Ipod Nano. I have been trying to get to let me use it as a hard drive in my old PC in order to move some files that i need. After I did the first succesfull transfer, I uploaded a couple of movies that i had in my old computer and when i ejected the nano, it went completely black. I have tried to reset it and nothing happens, changed it from computers to charge up, not touched it, and rebotted my Ibook several times to se if it even recognizes it. And nothing happens, can somebody please help me? Thank you very much.
