I have a Toshiba M1712 DVD-ROM (firmware J004) drive and a SONY DRU 510A (firmware 1.1a).
If i check a DVD (- or +, R or RW) for errors with NERO scandisc (surface scan) on the SONY burner, i get no error indication at all, everythings perfect.
If i do the same check with the Toshiba, scandisc indicates several errors.
Same occurs using ISObuster; it takes only few seconds scanning, using the SONY burner drive but ages using the Toshiba drive.
What could be the reason for this, and what results to trust ?
Best regards Jorn
