Hmm, well,

>>> i = -1972144115
>>> '%X' % (pow(2, 32)-(~i+1))
'8A73780D'

Although my bitwise arithmetic's feeling pretty rusty..

But ---

C:\Games\Civilization III\Conquests>dir d:
 Volume in drive D is CIV3CQST
 Volume Serial Number is 49BC-31DB
...

>>> import win32api
>>> cdi = win32api.GetVolumeInformation('D:/')
>>> '%X' % cdi[1]
'49BC31DB'

So, on my system (ActivePython 2.4, WinXPpro) there is no need for magic.

I've got Mark Hammond's pywin32 book, but it doesn't talk about
win32api.GetVolumeInformation().
