I have tried all of that, the OEM one is set to cable selct, i tried that, i tried as a master and master single, master with legacy support, master with 15 heads instead of 16 (theres tons of settings on the DeskStar hard drives.) The thing is it runs fine with the OEM drive and a 2nd one hooked up, i can access it with no issues, but if its hooked up the installer DVD locks up >_
