Test any Samsung203b or even the 223f on whichever sata controller/interface with +R bitset to DVD-ROM and wait until 99% of the disc finalising to see/witness any issues (ImgBurn with log window open. One example being [PMA Update Failure].

I only get this particular issue/s with Sammy/TSST drives on 3 of the 4 different Samsung drives I own.

When they are good they are good, when they are bad they are bad. (Very Hit 'n' Miss on DVD+SL) IMO
