ProDOS doesn't *do* anything with volume numbers, and it never displays
them, that is true. But the volume number is part of every floppy disk
block header, on 5.25" disks at least. Since the decision was made by
Apple that ProDOS should use the same low level format for 5.25" disks
as DOS 3.3, the now-useless volume number field in the block headers had
to stay. I think the standard formatting programs for ProDOS, such as
FILER and the later Apple Disk Utilities, always use #1 as the number
they put in there, but don't quote me on it. In DOS the standard value
is #254 but can be changed of course.
