if you have too many bus powered (or Dock Powered drives without enough power from the dock) then drives might start to act goofy.

Your whole Mac acting goofy for that reason would be a new diagnosis not seen in its Plain form here. But that situation is so convoluted it would be very hard to discover, but not far-fetched. Generally speaking systems respond to power over-draw with an uncontrolled power-down to avoid power supply damage.

There is a method for observing bus current required and available for each drive.

Also, be sure you run the diagnostic with all the drives connected. Maybe it will measure the current draw.
