ok, so when the ipod says do not disconnect, it really means do not disconnect. unfortunately, i didn't realize it said that until afterwards. now my catalog b structure is corrupt, and apple's disk utility won't fix it. i tried using techtools pro and when it wanted to restructure the catalog, it was to get rid of over half the stuff. i hit cancel when it asked me. i really do need the data off of it. what are my other options? the guy at the apple store mentioned using terminal to do a batch copy, but i'd like some feedback on what to do, and how to do it. i really do need the data that's on it, and i know i should have a back up somewhere, but i don't, and now it's my problem. thanks, Ryan edit!- i used disk warrior, and it just rebuilt the directory on my ipod. it works perfectly now!
