(note that I'm switching things around, so this is the same disk even 
though it now lives at sd0)

# fsck /dev/rsd0a
fsck: cannot open `/dev/rsd0a': Device busy
# scsictl sd0 start
# fsck /dev/rsd0a 
** /dev/rsd0a
** File system is clean; not checking
#


Another weird thing is  that in some of the (still unworking) 
configurations, I hear the drive spin up at boot, even though it _still_ 
doesn't work without the 'start'.  :/
