In randomness is not necessary (as I understood) you can just create
one single file and then modify one bit of it iteratively for 1000
times.
It's enough to make the checksum change.

Is there a way to create a file to big withouth actually writing
anything in python (just give me the garbage that is already on the
disk)?
