--- Comment #18 from Alexander Motin <mav@FreeBSD.org> ---
Format Device mode page reports physical sector size, not physical block si=
ze.=20
That concept is used for bad block marking/relocation and appeared very ear=
ly
in SCSI specs, long before logical blocks being formalized in SBC-3.  Since
Format Device mode page is obsolete since SBC-2 specification, released alm=
ost
20 years ago, it is hard to guess what would be its meaning in today's term=
s,
but I suppose physical sector smaller than physical block would not make se=
nse.
 So I'll update the code to report physical block size there instead of log=
ical
block size.  But after that I have a strong itch to remove Format Device mo=
de
page together with Rigid Disk Geometry mode page, obsoleted for the same 20
years.
