I tried to burn backup copy of Safedisk 2.9 games (Sims Superstar, BF1942 secret weapons, Tropico 2). I tried Alcohol and Blindwrite, lot of different settings. I tried to burn on Plextor Premium, LiteOn 4812, Toshiba SD-R5002. All my backups works without any problems on different CD-ROMs (no emulation). except Sony 1621 DVD-ROM. When I try run backup from this drive, I always get error in ~df123.tmp (not remember exactly). What a special with this drive? If somebody has burned copy that works on this drive (without any kind of emulation) , could you tell me how you did it (software, burner, settings)? Thanks.
