How do I get the volume serial number for a drive? For example in the
cmd prompt issuing this:
C:\>vol C:
Volume in drive C is LABEL
Volume Serial Number is FFFF-0000
Is the volume serial number wrapped by pywin32? I found the function
win32api.GetVolumeInformation, but it doesn’t seem to return what I want.
Yes, actually, it does. The second item in the tuple it returns is the
VSN as a 32-bit binary value.
You were probably confused because Python showed it to you as a signed
decimal integer. If your VSN is really FFFF-0000, then it probably
showed you -65535. If you print that in hex, you get -FFFF, and if you
treat that as unsigned, you get FFFF0000.
I wish I knew a better way to do the signed/unsigned mangling, but try this:
def UnsignedHex( v ):
if v >= 0: return '%08X' % v
return '%08X' % (0x100000000 + v )
print UnsignedHex( win32api.GetVolumeInformation('C:\\')[1] )
