Well, the airflow is good, seems that the drives don't get cooled enough in their current position. I removed da3 from the chain, and moved da2 to the outer position and set it to term and term from drive. Now lets see how this behaves. I will be looking at something to cool the drives better. Any suggestions are of course welcome to improve this. I cannot at the moment place any HD at the end of the other chain since those are 3.5" drives and the mount area is 5.25", so I need to get some mount brackets before I can attempt this. Another mistake on my part, it is empty stub---cdrom----terminator, not what I said earlier: cdrom----empty stub----terminator.
