Well I straightened out my IRQ mess with win2000 but now have found out that really was not the problem.
I have a Seagate Ultra 160 SCA drive with a converter on it to make it fit a 68 pin connector. The problem is when the drive is in use it keeps resetting the SCSI bus and the drive eventually disconnects. Yes, everything is properly terminated and is running on an Adaptec 29160n card. The small converter I have has an eight(I think) pin-out that is 9-line negation termination. What is that? How do I use it and will that solve my disconecting problem? Argh! I wanna use my 18 gigs!!!
Here is the connector that I have if it helps.(the last adapter on the page)

I have had nothing but trouble with those adapters.

I had an 18gig Barracuda that was doing the same thing. I figured the drive was bad, but the adapter was causing the problem & the adapter was brand new.

So what did you do? I was told I might actually have the wrong adapter and the drive is brand new. Hmmm... maybe. Anyone?

I replaced the adapter, sold the drive, & used nothing but 68pin drives from then on.

I have an Adaptec 39160 running an X-15 Cheetah & four older 10,000rpm Cheetahs.

Anyone want to buy or trade for this drive!?!?!

Some of those adapters aren't LVD rated and there are either little to no documentations that comes w/them. I've had vendors who had no clues other than the fact that they claimed "it worked in our in house testing setup" (yeah, right) and don't really mention that part.

That last adapter w/ the 50Pin > 68/80 Pin is the one you have? If it has 50 pin I could almost garrantee that it's not LVD/U2W/Ultra160 rated. I bought two such adapters a while back (Compucheap) and it was nothing but problems until I found out that the card wasn't made for LVD drives. Once I replaced it, it was smooth ride that is at least until I sold it off recently.

First of all, you don't use any jumpers on that board for anything other than to set scsi ID# and that's only for ID # higher than "0" of course. They're not my first choice but they're OK once you get the right one and set it up right.

Hehe, haven't been here for a while ...

You would need the first of the adapters on the page, it say LVD ... the one you got is only good for SE drives (up to 40MB/s UW).
I still have an old IBM 18XP 7.2k HDD that is SCA and required LVD ... those were expensive 2 years ago ...
