Even _not_ using a hash will have collisions - copy different globs of
data around enough, and sooner or later, two globs that started out
different will end up the same, due to errors in our computers. Even
ECC on all the buses, channels, and memory will just reduce this chance.
There is no mathematical perfection obtainable here. Deal with it.
Computers are about engineering, not philosophical perfection.
If something is likely to happen less than once in a billion years,
then for all practical purposes, it won't happen.
