1. Actual drive letter is G:, it is prefaced by an identifier: T7 Shield (G:)
2. I hadn't been using RealBand, so I tried doing so - it also couldn't find the G: drive RealDrums, but seemed to know where the RealTracks were.

But, after opening and closing RealBand, then opening BIAB....now BIAB is retaining the RealTracks and RealDrums G: drive preference settings!!!!!

Does RealBand just rely on the BIAB preferences for RealTrack locations? I can't find an option to change that in RealBand.

And thanks everyone for your input!
