Simple: Because you only created 50% redundancy for it. If you
created 100% redundancy, it would work. But only 50% means that the
other 50% would still be random data.

Most parity-generation tools generate a managable amount of parity
information; RAR defaults to 1% (to handle small errors); or you could
use PAR to generate large amounts of parity that would recover one or
more chunks of a multi-part file. But it doesn't work miracles :-)
