here is a bad disc, 6x CAV
Here is the same disc, 6x CLV
If you haven't noticed already, there is a great difference in the last 200 megabytes. While I haven't finished the 8x scan yet, I knew this disc was bad when I did the 6x CAV. Or wait, is it bad? Because according to 6x CLV its fine.
I guess the only way to know for sure is do a 1x scan of the last 400 megabytes, I will post one in a few.
