Same discs Kprobed with the QS0B firmware:
C1 is down in both, but the # of C2 errors is nearly the same, which has me worried. Maybe it was just an anomaly with that one TY burn. This will require another test...too bad I only have 3 TY's left.
In the C1 dept, I'm not sure the writing quality is any worse than the QS0B firmware, and if it is, the degradation is negligible.
