chunks (as it's smallest possible file), the minimum of 9 sectors (1 gran=9
sectors). OS9 relies on the setting in the device descriptor for it's
minimum.

Its below the filesystem level, so decb/RBF isn't involved (though of
course they would never create a filesystem where there weren't whole
sectors).

I believe its for loading individual files, not filesystems/disk images.
DW doesn't care really what is in the "sectors", so as long as the client
side can figure it out that's OK
