Name/ID of removable Media: how?

[Claudio Grondi]

Maybe the function below can help?
I suppose WMI returns same values as FSO (File System Object):

def  strDriveHexSerialNumberFromFSOintRetVal(intDriveSerialNumberByFSO):
  """Supplied with an integer representing a drive serial number returns the
  number in same format as \>dir command does (i.e. ####-####)."""
  # The value of axDrive.SerialNumber property (an int or float number) can
be
  # negative, so to get always a positive number as listed by e.g. \>dir
  # command it is necessary to apply a workaround:
  if(intDriveSerialNumberByFSO < 0):
    # dec 4294967295 == hex FFFFFFFF, dec 4294967296 == hex 100000000
    intDriveSerialNumber = 4294967296L + intDriveSerialNumberByFSO
  else:
    intDriveSerialNumber = intDriveSerialNumberByFSO
  #:if/else
  strHexSerialNumber = "%08X"%intDriveSerialNumber
  strHexSerialNumber = strHexSerialNumber[:4]+"-"+strHexSerialNumber[4:]
  return strHexSerialNumber
#:def  strDriveHexSerialNumberFromFSOintRetVal(intDriveSerialNumberByFSO)

In your case
strDriveHexSerialNumberFromFSOintRetVal(-793919769):
gives:
D0AD-BEE7
