Hi! I have a LG UH12NS30 in a PC running Win7. I wanted to use DiscSpeed to test some BD-Rs. It correctly identifies them as CMCMAGBA5 under Disc Info. But all test options (xfer rate, create data disc, etc.) are grayed out. I had also tried Speed 4.11 with same result. At least I could create and check a DVD-R.
Is there something needed to unlock the BD-R capability?

Are you sure that your drive supports these tests? As far as I know LG drives generally don't and personally I never came across with one that does.
Thank you for your reply! Mystery solved, it was my fault, I didn't realize this model can't record BD. The specs say "DVD±RW (±R DL) / DVD-RAM / BD-ROM drive".
