[rescue] SCSI adapter help...

I'm making a last effort to try and get some of my new gear working --
at the moment, my biggest problem is the SCA<->50pin adapters and WD SCA
drives I bought to put in the Indy and Indigo2. I'm hoping someone will
be willing to help me troubleshoot.
The adapters are relatively simple, and come with a clearly written
sheet of instructions. The jumper block is labeled as follows:
The DLY and MTR options control forced delay and remote delay. SYN is
for some kinc of SCA sync option, apparently. The others should be
obvious. The adapter instructions do say that the settings on the
adapter and on the drive should be exactly matched, at least as far as
SCSI ID, and I've been doing that. I've also fiddled with a few other
jumpers on and off, and the Indy I'm connecting these drives to always
claims that there's been a SCSI controller failure if this drive is the
only one connected -- just like if there's nothing at all attached to
the bus. It also doesn't get recognized if it's attached along with
another, working (50pin) drive. I've also fiddled as best I can with
The jumpers on the drive are a lot more complex, and I don't pretend to
understand half of them. The WD site lists only two jumper layouts for
SCSI drives, and this is not one of them. Here's the jumper block
labeling from the drive top label:
D TRGT INIT
D UNIT ATTN
The drive comes with RMT START and D TRGT INIT jumpered by default. I've
tried both jumpered and unjumpered. I've also tried the drive on all the
SCSI ID jumpers, both matched with the adapter and not matched. I've got
no clue what to do next.
I'd dearly appreciate any help I can get.
