Burns 4X and 2X Sony BD-R DL at 1X with XP/Nero, and the 4X burns at 2X on Win7/Roxio. Its rated as 4X write for DL, even read speeds are slow. I'm burning data discs in UDF. Any explanations?
can I move this to the blu ray forum?
Disable the BD defect management option and they'll burn at rated speed ...
how do I do that? also, how do I know the drive isn't defective?
