I went back to 4.6-Release (world & kernel), and that did not fix the problem. I'm back on today's STABLE. I broke the mirror and tested each drive separately on the HPT controller in DMA mode - there were no problems. I recreated the mirror and the corruption of large files came back. The problem only occurs when the two drives are in a RAID1 array on the HPT controller and DMA is enabled. I would think that if this was a hardware problem, one of the two drives in the RAID1 array would have had some corruption problems when it was taken out of the array and addressed as a single drive.
