OK the place where I have seen this before is when someone is trying
to do that. Usually the drive is not getting enough power and will
flake out. The only fix was to put them in an external case with a
separate power supply. The SSD drives seem to come up a lot. I don't
know if it is an amperage issue or something else, but they expect
something that the USB3.1 isn't delivering. I would try putting them
in a case which does accept external power and see if it works better.
