I tried to back-up my CD; Toots and the Maytals - True Love.
CloneCD 22.214.171.124 did it with the it's plain everyday Audio CD Profile.
I noticed when it got above 97% that the drive spead up, slowed down, spead up and slowed down several times.
I was able to listen to the back-up disc on my home stereo CD player.
I used ClonyXXL 126.96.36.199 to find that the original disc has dummy files.
I started CloneCD from ClonyXXL and selected the _ClonyXXL Profile.
When the read got to 96%, the remaining time changed to Unkown.
I stoped the read.
I used ClonyXXL to find that another Audio CD has Dummy Files and OverBurn.
I backed it up successfully with CCD's plain everyday Audio CD Profile.
