I When i sync my ipod it gets a spinning wheel and then reboots itself, but while this is all happening it still syncs. But sometimes not all the way. It says attempting to copy the disk "ipod" failed. this device is not connected. And it also says that its corrupted or something after that, but im still able to sync and stuff through itunes. I havent tried syncing just songs yet, only syncing apps and songs. Has any one else had this problem? How can i fix it?
