ok, so first off, sorry for the potential repost. I couldn't find the answer on the forum so I am starting a new thread. Let's say I have a 50gb music library. I want to put all 50gb on the external, and keep about 30gb on my iBook. That part was easy enough, however I am running into problems keeping everything in my library located. Everytime I disconnect and then reconnect the external, anything that's not on my iBook can't be located. I want to make it so that when the external is not connected, my entire library (EXT and INT) is shown[obviously, I won't be able to play anything that resides on the EXT], and when I connect the EXT, I want it to locate the files that are external only. Is this possible? Thanks! Matt p.s. I also want iTunes to keep my folders organized, there, that's the kicker.
