I've got the same issue with this card. I've tried the OCZ Agility 60GB SSD, Hitachi 1TB SATA HDD, and a Seagate 60GB 2.5" SATA HDD. None of them are shown in the webbios. I RMA'ed the controller thinking it was defective, but the replacement does the exact same thing. The only thing I can think of are incompatible cables. I'm using this one from ebay: http://cgi.ebay.com/ws/eBayISAPI.dll...m=170423773187

Does anyone have recommendations for cables that are guaranteed to work?
