wanted: info on switch settings for NEC D2363 SMD disk

Post by Wilko Bul » Sun, 14 Aug 1994 17:35:51

I am looking for info on the dipswitch settings for the NEC D2363 disk.
Especially the sector switches. I do have the settings for Sun

Who has the tech docs of this drive and can send me this info?
Preferably by email.

from a Sun 3/160, added to a Sun 4/390.  The controller seems

when used on the disk (in fact, SCSI disk access and possibly
IPI disk access hangs as well).  Now it appears that I can't
even find the disk on power-up (although I still find the

On the front of the disk drive it has a little display panel (labelled
SD231 status display).  The left digit is marked "state", the right
digit is marked "error".  The displayed values (at present) are:


What does this mean?
What should it be?
Is there any hope?

(I would like to salvage the disk if possible, disk space is always

PS: there are two switches on the display panel.  The first is labelled
"diagnostic enable/status only" and is set to "status only".  The
second is labelled "extended mode/normal mode" and is set to "normal

PPS: in case it worries anybody - I have removed the two jumpers from the
backplane for slot 10 (where the 7053 crad is), and the only cards in the
machine are the CPU, 32 Mbyte extra memory, CM-2 interface, IPI controller,
and colour Sun console interface.
