hey.

my multia died today for reasons as-yet unknown (could be heat stroke :))
but when i plugged the 4 gig SCSI from the multia into my netbsd macppc
machine, it refuses to see a disklabel.  (this is *really* bad since i
have a mail spool and ~/mail tree i *need* to jank off the disk.)

dmesg says:

uname on the macppc says:

NetBSD eloso 1.5 NetBSD 1.5 (GENERIC) #1: Sun Nov 19 13:58:47 PST 2000
matt@duel.local:/u1/kobj/GENERIC macppc

it's a 9500/180MP.

i'll be hooking up myself a DDS2 tonight to prevent future problems.  :P
