So I'm thinking of moving my music to an external drive as I currently have 288.7 MB available. I'm wondering what would happen then if I connected my iPhone without the external drive connected. Would media be deleted? Would it not want to sync? What issues would I have with this setup? Alternatively, is there a way I can keep the playlist of music the iPhone syncs with on my computer? It seems like that would probably be pretty messy, especially since it's a smart playlist affected by last played, play count and rating. Anyway, please share your thoughts. Thanks.
