Whenever I try adding songs to my Ipod (4th gen, 40gb), it gets through about 20 - 30 songs then comes up with a failure that reads: Attempting to copy to the disk "My Ipod" failed. The disk could not be read from or written to. I just reformatted my Ipod in hopes that it would fix the problem, but it hasn't. The songs are transfered fine, but only 20 at a time. Any ideas?
