I've got a Dell Precision 470 with an internal striped raid. It originally came with windows XP64 installed. I've got it currently setup to dual boot xp64 and Vista business 64 with one more blank partition for "messing around". This is a test pc that I use to test software on various OS so if I mess it up, only time is lost to reset it up. When I installed Vista, it wouldn't see my sata raid. When I download the raid drivers from the Dell website (I also tried the drivers on the adaptec site) and put them on a flash drive and click the "load drivers", it told me they weren't compatable. I would try them anyway but thyey wouldnt' ever work. Eventually I got it to work by loading the old XP64 raid drivers off the dell XP64 windows install disc. Unfortunately, in the Windows 7 install, this isn't working. Any ideas?
