(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.
