I've always wondered if the label could lie about the physical sector size?
Making it look like you'd copied a disk image from a disk with (say) 8k sectors!
But I don't think the fs support for large sectors is adequately phyical
sector size agnostic.
8k sectors, 8k fragments and 64k blocks should work for FFSv1 and FFSv2.
