I had that happen when I was getting read errors from my cdrom, I ended up
having to read from my burner pending a purchase of a new cdrom.
I did get reported errors at the time. I doubt that the gui tools will do any 
better AFAIK they are just front ends to the commandline cdtools.

Maybe `readcd` to copy your iso, I've just used it to try and recover a
botched up cdr that went wrong during fixation, unsuccessfully in this
case.
