I loaded up the raid drivers the error message went from devise manager, thought I would have to reboot and then initilise the hard disks went in to my computer just in case and they were both there. All up and running couldn't belive I didn't even have to re-boot.
Thank you very much for your help my next project is to build a new computer I was going to buy one from overclockers for nearly £2,500 but looking at advice on here I think I'll save myself a small fortune
