is there somebody able to tell me what is the difference between unofficial gs0a and official gs0c?
I used my 451@851 with gs0a and everything was fine. Then I loaded the new gs0c and the scan results of KProbe were worse.
Using gs0a I had PImax 300 an POmax 20 at worst. Using gs0c the values rose up to PImax 600-800 and POmax 40-50. I use still the same media Verbatim +R @8x or Imation +R @8x. Both are originally labeled as 4x, but allow burning @ 8x.
