I have a Mac Pro. I have a 1TB drive I use as my iTunes library. In iTunes, I have the library set to /volumes/hard_drive/iTunes Library/. I drag media to iTunes, and it adds it to the iTunes library on that drive. So I can then delete the original source. But seemingly at random, iTunes will create a ~/Music/iTunes in my user home folder (where it would be if I didn't change the iTunes prefs). What is up with this? By the dates on the folders, it seems to have just done this from Dec 4th to Dec 12th. Why would this be? So now my library is split between 2 locations. I can go through and fix this, but I never know when it has happened, and I want to prevent it in the future. Ideas?
