"Not big enough", or "can't make an array that big"?
In any case, I don't see anything wrong with your
code. It runs fine on my machine and makes a lovely
HDF file with a huge volume filled with zeros. :-)
Cheers,

P.S. If the message, was "can't make an array that big",
then I suspect you don't have enough process or virtual
memory to work with 7 MBytes of data all at once. You will
have to get more. But we need more details to advice you
sensibly.
