I have read numerous threads, and can't figure it out. There was a huge post on iLounge, but it didn't seem to work for my situation. I just had to wipe my Macbook, and install Snow Leopard. It is my main computer now and I need to run my itunes off of an external drive. The library is bigger than the HD - so I copied the "iTunes Music" folder to the external drive. I now have a brand new clean install of snow leopard, and the itunes music folder with all my media on an external drive. What is the next step for this specific situation? Do I need to change the location of the database file and hit "consolidate"? I read somewhere that it wouldn't work like that. I'm just trying to make this transition as smooth as possible...going forward the external should be plugged in pretty much all the time.
