   You need a bit more than hashes to do “repair capability”. That means   
   error *correction*, not just *detection*.   
      
   For example, optical media make heavy use of Reed-Solomon   
   Cross-Interleave Redundancy Checking, applied at two separate levels:   
   one as an error-correction code and the other as an erasure code. As I   
   recall, on DVD, this redundancy overhead reduces the effective storage   
   capacity by about half.
