(Label isn't _that_ misleading :-)
Well, every SCSI disk I've ever purchased has been low-level formatted at
the factory. A SCSI formatting utility shouldn't be that hard to write
(it's a matter of setting a couple of page parameters and sending a
format unit command), but a nice, well-rounded SCSI device manipulation
tool is a little harder :-)

That statement is extremely misleading. I know of cases where a disk was
fresh-from-the-factory and NetBSD installed on it.
