My 1635s on YS0V can’t burn CD-Rs at 8x. At 16x and up everything is fine. Is it firmware related? The disc is still usable, though.
I suspect that 16x may be the slowest burn speed for CD-R in the 1635S but I can’t confirm that at the moment…
Edit: I just checked with Nero InfoTool and it says that the valid CD-R speeds are (6x, 12x, 20x, 24x, 32x, 40x, 48x), so it looks like 8x isn’t a valid speed choice.
Thanks for replying. It must be Nero related because I’ve just burned that very same disc using WinOnCD 6 with the speed set at 8x and everything went OK.
