	Hmm. After this patch my RZ24 drive stopped giving me 'short
write' errors when copying larger files (over 3.5MB) and works fine. Its
seems that even a bit faster than before :-) 
	Of course, it may be some kind a weirdness this drive has. NetBSD
installation failed to disklabel it etc. but worked OK when I tried to
install onto 500MB Seagate (actually not very OK, it crashed just before
completing newfs on it).
	Yet some questions: disklabel seems to write boot blocks onto
disk, but when I try to boot from disk it says 'Boot failed, saerrno 2'.
Have I done something wrong or it just doesn't work? (VS3100m38)

	Is it possible to temporarily shut down SCSI drives not used for a
while? (Kinda power save mode).
