I just plugged my NEC ND3500A in, and shuffled my oldish Ricoh DVDRom/CDRW into master on the cable. both drives windows show as "CD drive" in my computer, but device manager shows up their proper names and Nero just burnt to it fine. If i right click and go to properties for the drive, both of them show as a 'DVD/CDRom drives'.
Guess what i'm trying to say is if nero burns to it ok, its fine. Else, bit stumpted, try going into auto detect drives in bios? check cable plugged in properly?
An oddity i've noticed though, is that in the "recording" tab of the drives' properties, XP only seems to want to have a tick beside "enable cd recording on this drive" on one or the other of the drives, it's usually taking the tick off of the Ricoh but it once did it the other way around.
