Hi, I have a Plextor 121032A writer that is with a sony dvd drive in a same secondary IDE channel, I have this problem with nero is occasionally when i burn CDs, a SCSI/IDE error appear from the nero dialog and the application hangs there, burn-proof is activited and my firmware is 1.07. What could be the cause of this? Is is because of the media or due to any other reasons like Power supply? I'm running my cd-writer at default pio mode 4. Can anybody help?
