ok, i'm not asking for help. i was just too happy for finding the great solution for this problem i was enduring for a while and wanted to share: i have an external drive with all my music. but all this description would work just the same for an ipod. when i or sb else try to play a song with the ext hd out, itunes doesn't find it and keeps the ****ing "!" besides it (and doesn't play it anymore). itunes believes it's dead. BUT IT'S NOT DEAD. IT DIDN'T EVEN CHANGE ITS LOCATION! even if i reconnect the ext hd, it won't play that songs till i expecitly choose it. what can be quite boring when there are too many songs like that and i have to double click them one by one. an alternative would be restarting the library from scratch, but i'd loose my ratings, playing counters, etc. so, this link http://blog.davenicoll.com/2009/04/...rack-with-an-exclamation-mark-is-not-missing/ just gave me the final solution: start itunes pressing the "ctrl" key. (with the hd/ipod connected, for sure) and those marks will be gone! simple like that! that's it. hope to be helping.
