Yes, but that can be taken into account beforehand by the recording 
program, by using self-correctable byte codes and sectors, so that errors 
in the media (a bad sector, for instance) can not simply be detected, but 
also corrected.

Does that exist in Linux? I have used that method almost 20 years ago in 
MsDos, with floppy backups. Why don't we have that in Linux?
