Well difficult to tell, as I just left the machine in the night
alone, mc doing all the copying, but the screen was all the time full
of error messages. Steven would probably say: do not use mc.

This is very interesting. When I tried cmp or under DOS fc I realized
that it would hardly be faster than doing all the copying hd copying
again.

On the other hand I wonder how this magic can this work. If you have
two equally long non-redundant file, how can such a small number
grant that their content is identical? Any mathematicians around, who
can explain this?
