Need IBM WDS-3160 specs and Conner cp30100 specs major trouble

As my post says I need the specs of both drives, paticularly the type of termination (active, etc). (I am definately NOT a SCSI savvy person)

Heres my problem I have a proprietary graphics computer that uses standard SCSI hard drives up to about 340mb for saving images. It is compatible with most Quantum LPS/Prodrive and Conner drives, especially the 120mb and 270mb versions.
Anyway I got a large number of IBM WDS3160's due to the lack of the latter and they do not work properly.

With the ibm drives I have problems with line noise and detection.

What is the difference (electronically) between an IBM WDS-3160 and a Conner 30100 drive? Is there any way I can get the IBM drive to function similarly to a Conner 30100?

Please note that I am only using one drive in the system.

Thanx for any help

 

I believe I've found a difference between the two drives, it seems that the conner unit automatically enables SCSI parity and the ibm drive makes no mention of it.
Do any of you think this could be the issue? If so how would I enable parity on the ibm drive?

Thanx
