New Hard Drive Crashing Pro Tools 10.3.8

Just got a brand new G Drive Mini 1TB. I copied (drag n drop) all my PT sessions to it from my older 500GB G Drive Mini. Now when I launch PT 10, it will either hang on start up or when a song is open it will crash on playback or when trying to save. I've used "disk utility" - repairing,erasing,re-formatting etc; even trashing all prefs and zapping PRAM of the computer.



It's really driving me bonkerz!!!



ANYBODY???? (Help...)
