it is the external (option 4) card that has my cloned os on it. i removed the internal card and the external card, let it boot to flash and then put the external card back in. still says failed when i try to boot from the external card partition. the card is a pny optima 4GB card. i was booting from it most of the day right before i booted in diablo and ran the update. any more suggestions would be great.
