I have a 500GB drive that is formatted to HFS+ Journaled. It stores all of my iTunes music (over 200GB) and for the remainder of the space I am using it as my Time Machine drive. Will Time Machine start deleting my music when the storage on it starts running out? How about if I want to add new music and the space is already filled from Time Machine? Just wondering how this works.. If I should purchase a different drive entirely for Time Machine I can look into doing that too..
