Host is a HP 9000/382
Copied the orig drive using a linux box, adaptec 2940N and good old dd
Then swapped drives, a unused 9 GB 80 pin with a Chinese 80 to 50
adapter.
Did have to issue a spin up command and then copied the data to this drive
again with dd.
Powered all off, added a motor start jumper to the adapter and put it on the
9000/382. Motor will not start, added a jumper right on the drive, no spin.
so .. any ideas what I'm doing wrong, or just try a different drive ?

The HP 9000/382 only supports SE scsi and the drive needs to be terminated.

Found at least one issue, open trace next to a via on the adapter. Ran out
of time to keep checking.

I just checked my HP 9000/382 and found I put the dead original
Quantum 50-pin SCSI hard drive back in it. I must have been using a
68-pin 9GB SCSI hard drive the last time I was tinkering with it, with
a 50-pin male / 68-pin male adapter. I don't remember having any
issues with that configuration.
I did a clean install of HP-UX 9.10 on my 9000/382 from a B2378-87054
CD image I got from hpmuseum.net

I took a closer look at the adapter, and not only is the an cracked trace
next to a via but a soldering? short. The place in CN is sending me
another one. For now I have put back the original drive. Somewhere in the
junk is the solution to the next issue, either an old hub Tha has coax/BNC
or the box of MAUs that came with the pallet of Sun pizza s
-Pete to much junk

Well if the drive has an 80 pin SCA interface there is a chance that it
is a LVD drive, which normally would be ok since LVD devices are obliged
by the SCSI spec to be able to operate in SE mode as well, but the
problem may be you 80 to 50 convertor. I have encounter some that are
not correctly wired and as a result do not always work. LVD SCSI
devices monitor a line call DIFFSENSE which is pin 46 on the SCA
connector for SE operation this pin needs to be grounded, it is also
possible that the drive itself has an option jumper to force SE mode if
it is an LVD device. It would help if you mentioned what the model of
the drive in question is.

Further to my previous reply, did you use the same SCA to 50 pin
adapter? If so then that would suggest the adapter is OK. If you are
jumpering the drive to spin on power then it should start up as soon as
power is applied, the pins on the SCA connector that affect motor
operation are 38 RMT_START and 78 DLYD_START both should be left open
for spin on power. If RMT_START is grounded motor will only start on
command if DLD_START is grounded motor start will be delayed 12 seconds
X SCSI ID. Does the drive spin if it is not connected to the SCSI
bus? I suppose it is also possible that the drive does not support
"spin on power" so again knowing what drive model you are using would be
helpful.
Paul.
