With ASUS SBW-06D2X-U not writable

Have ordered a spindle of these blanks. Unfortunately, the first consignment of goods did not reach me. The supplier but sent a new shipment after a waiting period. Problem-free settlement.

To blank itself: Have him try to describe to my Mac with the SBW-06D2X-U from Asus. The burner spit out the blanks after a few seconds again and does not seem to recognize it. I tried all 10 undescribed blanks. Everywhere the same.
On my PC with an internal burner LG then almost everything went smoothly. From 10 discs 8 were described as desired. The other 2 have unfortunately canceled and were then useless. It's better.
