If I'm not mistaking, your mainboard comes with a driverdisk. Use that disk to install the drivers into Windows (best is to do this when installing your system, but it can be done afterwards as well). After that, in most cases, Windows immediately sees all the drives connected to the RAID controller...
hburrows83: right after typing the message above, I read your post in the other thread... so I splitted it and merged it with this thread, so there's just one thread for this particular problem
My suggestion: figure out what RAID controller is on your mainboard and download the driverdisk from the producer's website... install the driver and off you go!
