i was wondering if anyone knows what this option does
as it appears in the side bar window of copy cd/dvd in nero, i have nero 7.
and does it affect the speed or quality of the disc copy

It makes my PC write an unreadable CD and then lock up pretty solid during verifying.

I have no idea what it’s meant to do.
