It certainly is not easy. Self-correcting codes could probably be used, but that would be very special, very slow, and very non-standard. (Basically... we could design filesystem so that it would survive damage of arbitrarily 512K on disk -- using self-correcting codes in CD-like manner). I'm not sure if it would be practical.
