I've searched through the threads about using iTunes with music on an external hard drive but I still haven't found an answer to my question. I primarily want to keep my music on my Powerbook hard drive but there are some folders I have of music I'd prefer to keep on my external. Is there a way I can add this music from the external to itunes and use it only when the external is on? I have it in iTunes now but when the external is on and I go to play the track it dissapears from iTunes for some reason. Thanks in advance!
