Hi, I have an Asus Crosshair IV Formula AMD 890FX with 4 Internal Sata Drives, on the motherboard there is a block of 6 Sata connectors, 1-4 are connected to 4 Hard drives and work fine, 2 DVD Drives are connected to sata 5 & 6 and although they show on the Bios post they are not recognised at all when windows starts, is this a Bios problem or Windows 7 Problem, if i disconnect one and plug it into the other external sata connector also on the Motherboard they are recognised fine ???
I can see them on post and in Bios, but not on device manager or anything once running ???

Unfortunately no not even in there, really not sut the problem is, have tried uninstalling lots of stuff and they did briefly show up when i was removing catalyst manager for my Video card, as it was around then when they started to not work ?
