I have an old 9 GB IBM DNES-309170 HD that I would like to build into an
external SCSI subsystem. The drive das a 68-pin wide SCSI connector and I
use a 68-to-50 pin converter to hook up the internal cable. The subsystem is
connected to the single-ended connector of the on-board Adaptec U2W
controller of an Asus motherboard.

When the drive is connected to the bus and powered up, the system hangs when
it scans the SCSI units.

The drive is jumpered to SCSI unit 1 (which is not used by another device).
It has the following additional jumpers ('e' for enabled and 'd' for
disables):

- Enable auto-spin (e)
- SCSI termination (d; the subsystem has an external terminator)
- Disable unit attn (d)
- TI sync nego (d)
- Auto start delay (d)
- Delay start 6/12 (d)
- Disable parity (d)
- Term power on (e)

Is there anything wrong with my jumper settings?

You want that enabled.

Only one device has Term Power enabled.

That too, but there is with your cable when you hookup a wide drive to a wide controller.
Check your settings in the HA Setup.

Try one of these:

Some wide drives need high byte bias to come alive and the high byte
termination on the above supplies that bias.

You want that enabled.

He definitely should have parity enabled, but I thought he meant

that the "Disable parity" option is disabled, so parity is enabled.

Well, I tried with two of my 'vintage' drives. One is the IBM DNES-309170
mentioned before which has a wide SCSI interface. The other is a Segate
ST39102LW which is a U2W LVD drive. Both have a 68-pin connector. My
converter does have upper byte termination, and the drives' parity is of
course enabled.

With both drives connected to the 50-pin cable the behavior of my system is
identical: during boot-up the SCSI controller recognizes the drive and shows
the correct SCSI unit. After the controller has finished scanning the bus
the system hangs. As soon as I disconnect or power down the drive boot-up
continues.

What's wrong?

Haven't you been told already what is wrong?
Do you require spoon feeding?

Why so rude?

No, obviously not. I've been advised (by you) to enable "disable parity" and

by another contributor not to - neither setting made any difference. I've
checked that only one device has term power enabled. I was also told to use
a converter with upper bit termination, as I already do. Unfortunately none
of these measures had any effect.

I'm very grateful for any advice - even if it turns out not to be helpful
(at least almost anything is worth a try). But if you feel that my questions
are beneath you, just don't answer.

Because you obviously need 'awakening'.

Quote:

Yes, you did.

Quote:

No, to have it (parity) enabled.

Quote:

It certainly does if you have parity errors.

Typical how you left out:

" ... but there is with your cable when you hookup a wide drive
to a wide controller. Check your settings in the HA Setup".

Quote:

Strange then how you didn't do that and check the HA setup utility for
things related 'wide'.

Quote:

It's people that have an urge to rant and ignore suggestions that piss me off.
Apparently you need spoonfeeding:
Take your comforter out of your mouth.
Check the wide negotiation setting in the HA Setup.
Disable it.
Put your comforter back into your mouth.

He also told you that you shouldn't be connecting a wide device to a wide
controller with a narrow cable.

The right thing to do is use the correct cable. But if you really want to
get it to work with the wrong cable, try disabling wide negotiation.

Folkert:

However moronic I may appear to you - it's no justification for rudeness and
verbal abuse. It's a real pitty that you don't share your knowledge with a
bit more humility. Forums like this could benefit tremendously from people
like you, but that doesn't necessarily mean that less knowledgable
participants have to stay out.

controller). Anyway, disabeling wide negotiation in the controller for the
drive's SCSI unit did the trick - thanks a lot for the advice.

I gave you that advice.
All you had to do was follow it up and do a bit of thinking of your own.
You dismissed it when I gave it to you because I didn't feed it to you
with a spoon.

Me, rude? Don't you think that ignoring my advice -twice- wasn't immensely
rude? Don't you dare talk of being rude. Have a good look in the mirror first.

Quote:

Then show some respect and checkout things first before dismissing it
right out of hand. Even when reminded, you didn't bother to check it out.
Rather you chose to moan and deliberately misrepresent what was offered to you.

What makes you think that they don't? Not all are like yourself.

It's their choice to remain clueless if they choose so. No one is forcing them.

With good reason. I'm not going to defend Andreas' technical skills.
He does appear somewhat deficient in some areas, compared with others
in this group.

But his point is extremely well-taken. You, Eric, and Ron act as
though you are the arbitrators of social taste and 'correctness.'
There is an expression I grew up with, and I don't know how to say it
in languages other than English (although I speak decent French):

"Who died and made you king?"

Andreas is right by saying that you three Big Guys intimidate other
people from asking questions. Let me guess: In "real life," you do
technical support for end-users for large company. You are frustrated
by the fact that over 40% of all calls are for password-resets because
people are always forgetting their passwords.

And every day, you curse under your breath, but in reality, you need
the job and can't do anything about the end-users and their
forgetfulness. So where will you be recognized for the genius that
you really are?

Here in this forum. Here You are Somebody! Somebody Important!!
Very, Very Important. Important Enough that You can treat other
people like re-used dog shit.

Why? Because YOU know more than all the other people here and you
are not afraid to be rude. In real life, if you behaved towards other
people the way you treat them in this group, you would long ago have
been "sleeping with the fish," as they used to say in my old
neighborhood.

By the way, there is money to be made in helping people with their PC
problems. But such people can't get any business if they are always
insulting their clients.

Same goes for you, Eric, except you are a bit more circumspect. Just
a bit.

And Ron, well, you're not like those other two. Fortunately for your
karma. You're more like George Bush, who keeps repeating himself
regardless of the facts and circumstances. Too bad you aren't
standing for election.
