I noticed a bug in one of my BenQ DW1640s with firmware BSLB or BEFB, where if I turn SolidBurn ON for known media and try to burn RITEK F16, I end up with a disk that is unrecognized, essentially a coaster. The burn completes fine, but you can't scan the disk with CDSpeed, and if you unload and try to load it back in the same drive, the disk will not be recognized.
Burning RITEK F16 with BSRB and SolidBurn turned on for known media does NOT exhibit this problem.
Is this a known issue, or do I just have a bad drive? If not, can someone with a DW1640 and some RITEK F16 do a test using BSLB or BEFB? Turn SolidBurn ON for known media, then try some 8x, 12x, and 16x burns. Then try to quality scan the burns with CDSpeed after they finish. Also, unload the disk and then reload it into the same drive. See if the drive light goes solid and stays green.
