Another 716AL question

I am trying to rip a CD using Alcohol 120%. I get to almost 60% and hit almost 30x speed and then it drops suddenly to 2x-5x and stays like this consistently. I do not hear the cd spinning in the drive anymore. Is there a reason why it does not eventually max out or stay at 30x?

This is what I mean:

Are you using the same cd? Is it a burnt or pressed ? This disc may have a flaw/error in it.

I’m attempting to create a backup of a Windows XP Home SP2 Upgrade CD. I used the pressed CD to do the read test.

that cd isnt really a good idea. Doesnt microsoft put copy crotection on them? Why not just try another cd to see if you get the same results.
