I have a 40125S drive and every time I burn a CD @40x. It slows down to 24x at around 70% (55 Minutes). And Burn @24x till completion. It’s really strange.
I tried to turn SmartBurn On and Off. The problem keeps happening.
And tried different firmwares for 40125S, 40125W, 48125S. All have the problem.
I use FujiFilm 48x CD-R made by TY.
UDMA is ON.
