SCSI Adapters

[Striker]

I have an 80 pin SCSI HD that I am trying to put on my 68 pin SCSI cable by using an adapter. I set the jumpers on the adapter and when I connect it to the 68 pin cable, none of the drives on the SCSI chain will be recognized...I'm pretty sure there is a terminator on the end of the cable...

Can you post a picture of your connections ?

These are the hard drive interface and the cable interface

You need an adapter that has both interfaces, 80pin and 68pin interfaces and cable. Search engine will find one for you.

Yes, in my original comment I said I have such an adapter. Problem is when I hook it up, none of the drives will be recognized. Jumpers are set and the ribbon has a terminator on the end...

I misread your comment...are you saying that I need to get a new SCSI card that has both interfaces or just an 80 pin to 68 pin adapter? I have the little adapter.

I guess I was confused myself about your statement.
Some cards may not support a drive.
Try with another drive to ensure it is not a set up issue.
Also, is the drive a known working drive?

I have three drives that I bought from computer auction, i've tried all three with the same result. The fact that when i hook it up it disables my primary drive that always works tells me i'm doing something wrong...or maybe that particular drive is not compatible with my ultra 320 controller? I dunno

Do you have another drive connected to the same scsi hba ?

[Striker]

Ya, my primary hard drive runs off it...so when I try hooking up any one of these new drives up, my computer wont boot..I disconnect the drives and it boots fine. My primary drive is a 68 pin ultra 320 15,000 rpm scsi and the new drives i'm trying to get to work are 80 pin 10,000 rpm ultra 320 scsi drives.

Can you post a picture of your actual adapter and connections?

Here's the adapter

The adapter seems fine, so it's something else.

At times the corner pins inside the cable interface can get bent and prevent access.

[Striker]

Pins are fine, this is driving me nuts! LoL

The SCSI ID for the ribbon is 7, I set my primary drive to 4, set drive i'm trying to connect's adapter to 1....

Have you tried to connect the new drive on its own using the same SCSI ID as the working drive?

[fzabkar]

Could you tell us the model numbers of the HBA and your two drives? Could you also tell us their jumper settings?

AIUI, the interface can be either SE (single ended) or LVD (low voltage differential). You cannot mix the two interface types on the same cable.
