Bingo! I thought i'd checked all the ends but when I went to remove the short cable daisy-chaining the one good drive to the one bad drive, I found a bent pin on the end of the cable I had not previously checked. I was removing it because the first device was working in the chain and the second was not. Perhaps the cable itself was bad I thought. Turns out it was just a bent pin..
