In the last three days I have done quite a lot to make the QUANTUM 
PD425S runing together with NetBSD. The parity thing(if you mean to 
switch it off) I tried because of your mail just today after I played 
around with the disk in very many ways. I even bacame unsure if the disk 
is OK but today I put it onto a slow(2MB/s) PC-SCSI card and did 
a mediainit and a format and copied a whole directory to it and did some 
performance tests.

For now I can say that it doesn't seem to be the resistor thing. It 
was said to me that terminator resistor problems do just occur if the bus
is very long. I have these three HP2212 disks in the external box 
and also tried it without them. I put a second device onto the 
internal bus(actually not sure if it was correctly terminated - it was a 
Segate drive with a fitting set of resistors from another Segate drive), 
I used a internal scsi cable terminator that has to be plugged between 
the drive and the cable, I put it back into the HP box which has an 
external terminator.

All this did not change the NetBSD behavior.

Unfortunately I do not have the QUANTUM terminator resistor set
(three 8-pin-something resistors). Maybe someone has such a disk and can 
give me the exact parameters for the terminator resistor network. 

The only thing that made the situation a small bit different was when I 
closed the Wait Spin connector. Then the disk was at least identified 
correctly by NetBSD(I tested this under DOS as well and it worked in 
both situations). Although I still could not access it because 
the HP-SCSI controller doesn't seem to start a SCSI device if it is not 
started by itself. So I could not 'newfs' it under NetBSD or do any 
further things just because it is not running.

Maybe it can be started manually somehow?

I would be glad to receive further information about SCSI in NetBSD.
Maybe the HP-SCSI driver does not work properly or there is something
awkward with the respond of the Quantum when it is asked at kernel boot 
time. It seems if I increase the interleave in the disklabel that errors
reduce.

	Thanks for help and advice up to now
