I think that the volume number in the VTOC actually is *unrelated* to
the volume number encoded in the sector address fields. I seem to recall,
perhaps in the _DOSTalk Scrapbook_, some discussion which indicated
that DOS 3.3 itself made no effort to properly initialize this value
before formatting a disk.
