This works only in case that the OS correctly supports all features in the 
filesystem. As Linux does not support hard links correctly, callig mkisofs
again will not always result in an identical image and the new image might
not fit on the medium....

I recommend readcd as it reads directly from the medium and as it correctly 
informs you whether there was a read problem.
