For some reason when ever I try sync my ipod I get one of the following errors "Attempting to copy to the disk "Ipod Name Here" failed. The disc could not be read from or written." or " The iPod "Ipod Name Here" cannot be synced. The required disk cannot be found." I am on Windows 7 Ultimate. I have restored my iPod (it is no-longer jailbroken), restarted my PC, and uninstalled and reinstalled ITunes. What do I do? Ps: I took it to another PC and I can sync it. But I need to be able to sync it on my own computer.
