It's not quite that simple.  The trace showed that two different 
commands gave the right block size, and we don't know which one Windows 
believed.  I suppose we could figure out the answer to that.

It might work.  But the only justification would be "That's the way
Windows does it"... which might not be strong enough.  Especially since
different versions of Windows might do it in different ways.
