+my iPod has been giving me the same error 1418 everytime i restore it.. I did everything i possible could.. followed the steps of error 1413.+
The 1413 is a bit different from the other error message codes.
I know you've tried a couple of things from the following document (some of them are mentioned in the link deggie gave you), but have you tried all of them?
Error 1415, 1417, 1418, or 1428 when restoring or updating an iPod in iTunes 7 or later
