I have a raid setup-Dell 630i, factory Nvidia controller, dell bios with two 500gb drives acting as 1 1tb drive, stripping i believe-running win7 ultimate. I also have a pulled a drive-Out of dell xps 420- with windows vista home premium 750gb no raid single drive-acting up i think windows is shot-that I need to pull data off of-pics, scanned files, ect- I tried to install it but it will not load my Raid Win7 at boot menu, it pushed for win Vista and blue screens out. My question is am I doing something wrong? Or can you not slave in a single drive to a raid configuration? All Drives are SATA.
