Hi people

Just looking for a bit of help

Have a 80gb ipod classic (good few years old), never had a problem with it in the past, however few days ago had to restore it now when trying to sync it again with my macbook pro it gets to about 2465 songs out of 2488 and seems to hit a brick wall. Slows down ridiculously and if it manages to get to finalising sync itunes crashes >.<.

Any help would be appreciated, thanks in advance.
