I had this same problem when I copied an unnamed CD
I think it has something to do with how the source CD has stored the information.
I know back in the old days when you were only a twinkle in your mothers eye
They use to fragment the disks. Well thats what the old people tell me.
Wtf is a disk

The first time I tried to copy this CD it went well over 30min. So thinking something was wrong
I canceled it.
Second time same thing happened but only on the last 10% --went well over 30min again. So
once again I canceled it.
Third time just left it. Came back and it completed perfectly --> it took about 45min
And this is using the same burner as yourself but mine is 24x
