I moved my RAID 0 from my old system (DELL) to an Intel board in the past, didn't see any problems.
- You could try to verify the RAID 1 configuration using the RST application (there is a verify option in the manage options screen if you click on the RAID rectangle). Maybe there is a mismatch that the RST application can repair.
- RST 184.108.40.2060 was just released. You could try the 11.2 version to see if this issue was introduced with 11.6 (Intel had to pull v11.5 due to quality issue, and the 11.6 list of known issue in the readme.txt is very long).
We've tried the verify option like you said. It did find a lot of errors, and seems to have corrected them. So far we haven't noticed any more problems, and the windows logs don't show any new NTFS errors.
We'll keep watching the logs for now, but as far as I can tell, the verify solved the problem.
Thank you very much for the help.
