Right. I have an Epox 8RGA+ which, like most motherboards has two IDE channels. I just have the one hard disk, which is a 200GB Diamondmax 10. I previously had my NEC 3500 DVD burner as secondary master and a Yamaha CRW-F1 CD burner as secondary slave. Neither of those can do error scans though, so I recently yanked out the CRW-F1 and replaced it with a Lite-On SOHW-167 DVD-Rom drive (which can).
My problem is that I don't want to ditch the CRW-F1, because for some reason the 3500 does sucktacular CD burns (at least on the batch of discs I'm currently using), and also just because the F1 is the absolute daddy of all CD burners. Is there any good reason why I shouldn't go back to having the two burners on the secondary channel and put the DVD-Rom as primary slave? Since it's main job is doing quality scans, it should be fine on the same channel as the hard disk since they're not going to be used (much) at the same time, and that way I should be able to copy discs on the fly without getting buffer underruns as one channel will be reading and the other writing. I know that you can run different speed discs on the same IDE channel without slowing the faster one down....so is there any real-world reason why this would be a bad idea?
