Thanks Alex!

I am also aware that the 'serial' is not in the spec, but the specific sector
used by Microsoft appears to be consistent across different UDF revisions which
is why I believe it can be mapped by understanding the UDF spec. This would
also be more robust than guessing the sector based on the UDF revision.

I'm guessing the sector used for the serial is related to the start of the data
partition. The Partition Descriptor might hold the key: it appears to give the
correct sector for all volume types except in UDF 2.50/2.60 where it gives 288
instead of 320.
