Sorry for the delay, been travelling. Thanks for all of the suggestions so far. Yeah, I should have provided my configuration: I'm using the latest SONAR Platinum 18.104.22.168, with a Tascam US 16 x08 USB audio interface and a Nektar Impact 49 keyboard. Do you need my VST list?
Jim, you mentioned creating an "up-to-date back image file". Can you explain a bit more, not sure what you mean?
Maybe the best way would be to trade out hard drives? That's not ideal if I would like to get an SSD drive but maybe the safest. I guess I thought this would have come up before and there might be some "tool" to do this. Let me know what you think, and thanks again!
