I ahve a refurb 3g 10gb ipod i bought in may. Recently it has been acting up. Battery won't hold a charge, and resets automatically sometimes. Today when i went to update it on my mac, it wont even mount. All I get is an error saying that there are no volumes that mac osX can read. I've used reset it, my mac, used disk utility (which said that there was an invalid b-tree node), and when i went to use disk warrior, it said that the valoume wrapper was messed up and then it would quit. Any of you guys have similar problems?
