A little more information came to light today. I was looking through a directory of ‘junk’ on my PC and came across a list of media identifications I had done when I first installed BYX4 on this drive. I found two types of media that look funny.

So, though the drive can see that the manufacturer intended the media to be
faster, there is only that 1x write descriptor available. Strange.
