I had the same message several times recently in this PC. 10 IDE cables are connected. Happened regardless of drive so I thought it was a software bug since it never happened before and just swapping media one time solved it. (No noticeable permanent damage.)
Can you post a screen capture of that LOGICAL UNIT COMMUNICATION
CRC ERROR (ULTRA-DMA/32) message? Somehow it stopped happening here a few days ago. I'm burning and reading on all my DVD writers connected (Pioneer, LG, BenQ, Plextor...) so I didn't care.
