i found a problem while checking my discs with cd/dvd speed.
My burn quality looks really good but directly when this tool starts reading and dw1640 spins up it produces ~100-250 PI errors instantly. They vary from scan to scan on the same disc.
I exchanged all cables and firmware but nothing…ended up with firmware BSLB which seems to be very good (the only one without massive speed increase / decrease while burning).
Any ideas whats wrong? It messes up all my results.
Ah i forgot, that happens on all media except original discs
