I think with your soutbridge you can create a mirror from an existing drive. So, if you get your drivers setup right you can switch your BIOS SATA controller setting from IDE (or whatever it is in your BIOS) to RAID. If your computer boots then install the RAID software that comes with your motherboard. Once inside here you will find options to create the mirror. I'm not sure the exact steps, but I know it is somewhat intuitive with my motherboard.
Thank you very much guys. I have a M3A78-T with a 9950 and I have two Seagate 72000rpm 500BG (32MB cache) SATA 2.0 drives if that means anything to anyone I really should have told you earlier, my bad.
If I really must re-install then I will wait until I upgrade to 7 ultimate(after the first SP for it).
Once again TY for all the info I will look into making a mirror and hope that I can without re-install.
