Thanks for all your advice , guess I'm going to try the following:
- Re Install W8.1 64 onto the SSD
- Move the Sonar X3 program and associated files onto the SSD
- Depending on the space left I may put my current project onto the SSD whilst working on it and then Save as to the Old hard drives as a precaution until I'm more confident.
1 and 2 can always be reversed If anything goes wrong
3 most of my work is not critical , so it will be a good trial for the SSD reliability & speed.
Now I've just got to get my new Korg Triton Taktile to work with Sonar , happy days!
Thanks Again
Ric
