what is the best bay to flash firmware with these newer dvd writers. i've heard there could be conflicts if using intel storage drivers as well as raid drivers. i have a Pioneer109. Benq1620. and a Plextor 716A. i don't want to risk updating fimware for them with my storage and raid drivers installed. any suggestions on the safest way to flash these writers. perhaps safe mode? disabling dma? love to hear people's experiences. thanks.
