What are you going to do with it? You will get back a 20-byte string. The last 16-bytes are the binary GUID. The way you handle that depends on what you need to do with it. > You are right.

You should be using a string like "\\\\.\\E:" to open the volume for the E: drive (where the backslashes are doubled because of Python's string escaping).
