Hmm.. Actually I wonder whether the part about DeviceIOControl
answers it better.  Does that mean you can't do normal reads
and writes, in essence treating the hard drive as a big file?
That's very likely the case, in which case it looks like the
OP read the CreateFile docs above and just assumed it was
possible to read/write directly after opening the drive that
way.

But this probably still has nothing to do with Python, right?
