You either have a loose cable on one of the raid drives, a bad hardrive, or bad raid controller on your board. Do some basic troubleshooting. Try each drive separately without raid and see if both work. Can't tell you how to save your files; if the raid array is bad, you may have to start over. I don't use raid for this very reason. If you can't get the raid working, set one drive as master and the other as slave, or disconnect one and save it as a backup. The last option is to find the same motherboard on ebay. It must be exactly the same model if you want to try to save your raid setup. If you find one, you may be able to load the raid software in windows safe mode and reboot to see if the raid array is saved.
