It actually seems to have been power related. I'm using Icydock SATA disk chassis which have two molex power connectors and one SATA power connector for 3 drives. I had thought that the differing types made it an either/or situation, i.e. that it would be happy with the two molex. The "documentation" is what I would charitably call terse. Anyway after putting in the 3rd SATA power this problem went away.
