I've been trying for weeks to get my iPod to update itself, but everytime I plug it in to the dock I get an error message saying something like (translated from Swedish); "Unable to copy to the disc "iPod". Unable to read from or write to the disc." I've tried everything I can think of, restoring it with iTunes, reformatting it using the Disk Utility. Nothing has worked. The only way I have been able to update it is to try over and over and over again until it finally updates the few files I want it to. What can it be that causes it? The iPod is a 30gb 5.5g. Thanks in advance!
