Hi all

Maybe a strange question:

What's the difference between
'Drive writes regular bit patterns almost correctly'
and
'Drive writes regular bit patterns correctly' ?

I mean, what is NOT possible with a burner that writes the regular bit patterns "almost" correctly, but possible with one writing the RBP correctly?
Safedisc 2.51.2x sectors or something?

thanks
