>>>what if I open up a project that previously needed the hard drive, but I don't have it with me (on the train etc)?....

The song will still play, the missing RealTracks get replaced by silence. The missing RealDrums get replaced by MIDI Drums. The easiest thing to do (on a train, without any RealTracks), would just be to switch to a MIDI style.


Have Fun!
