Thanks for the reply.
All I can tell you is its a burner attribute called efm encoding, I found this out on another site. There is no info available other than the rating of various burners. They use the expression 2 sheep (drive writes regularbit patterns correctly). 1 Sheep (drive writes regular bit patterns almost correctly. 0 sheep (drive does not write regular bit patterns correctly.
Hope this helps.
