Yes, I guess I wasn't paying attention to the focus on partitions.
I wonder if you could try opening the physical disks (there is a weird
path prefix syntax IIRC) and read and interpret MBRs etc. for yourself.
Of course, you would need privilege to open raw disk reading, and you
definitely wouldn't want to make a mistake about read vs write ;-)

If ctypes becomes standard amongst the batteries included, this kind of
stuff should get easier, since I suppose you could use it to get to the
APIs you suggest (DeviceIoControl with IOCTL_DISK_GET_DRIVE_LAYOUT).

Kind of scary the damage you could do as administrator though, given that
on windows people tend to wind up running as administrator by default if they 
own
the machine ;-/
