I have all my music on my external hard drive and have my iTunes Music Folder Location set to the folder on the external. The problem is that I'm using a Powerbook so I have to disconnect my external drive often when I'm taking the computer with me. If by accident I try to play a track in iTunes while the drive is unplugged, then it resets the music folder location to the default on the computer. Every time, I have to change it back to the external then it takes a few seconds to go through the whole library again. Is there some script or something I can use to either force it to keep the external as the folder location no matter what, or to easily click to change it without having to go into advanced preferences everytime? Thanks!
