Iv'e installed the latest firmware, I just installed Nero 18.104.22.168 from 6.3.
I also tried the smart-burn suggestion, nothing seems to work.
Even tried putting the disc in before i start Nero, after I start Nero, and switching things up.
My master drive / other drive lets me select any speed so I have no clue.
I think my last resort is to switch them instead one master put it slave and other master instead of slave.
Is this what I should do, gonna try it in a bit?
If anyone has any other ideas or suggestions, be very helpful. Thanks Storm~
