True, but.... I can have two drives connected to SATA 1 and 2, and a third drive connected to SATA 3 sends things for a loop. If I do not connect anything to SATA 3 and 4,instead connecting 2 drives to the motherboard and 2 drives to my 3rd party RAID card... everything works fine... so with 3 drives I get failures, but with 4 it's fine as long as the 3rd and 4th are not plugged into the motherboard SATA controller. I have a fairly new 600W PSU from BeQuiet in the case... so there should be enough power for all devices. I have done some more digging, and it might be related to an obscure problem with the sata_nv kernel module. Some people are reporting similar problems.. not identical, but similar. I found most of the info via a long search through the mailing list archives at kernel.org (thanks for the pointer Felix). It only seems to affect some people though... and I am not clear yet what exactly is going wrong... or if there is a fix or patch to clear it up anywhere.
