I have an 80GB MacBook and a 70GB iTunes library, most of which is located on my external HD. Trouble is, that HD isn't always connected to my machine, and I often use iTunes when it isn't. As a result, I have a major discrepancy between my external and internal libraries. Is there a way to get iTunes to add all the new content from my MacBook to my external HD music folder whenever it connects? Another problem is that every time I try to play a song that's only on the external, iTunes says it can't find it and asks me if I would like to locate it. This happens even when I go into Preferences and select the appropriate folder on the external HD. Why can't iTunes just use Spotlight to search for the file (like I do) and play it? Does anyone else have this problem? Does anyone have a solution?
