I've been using a Gigabyte EP35-DS3R without problems in my computer, and yesterday I upgraded to an EP45-DS5 (rev 1.0) so I would have an extra couple of SATA ports and another PCIE 16x slot. I currently have 8 SATA hard drives, none in RAID. My DVD drive is IDE. When I plugged them in to the new motherboard and started it up, some of them weren't detected. I tried them in different ports in case
