Never heard of baddisk, what is that?

Anyway from what you’ve said, Linux on the Pi can’t see the SSD during
early boot, but can see it when attached to the Pi later. That’s hard to
explain, since it’s the same hardware and the same code looking for it
in each case.

Just to check, did you run your ‘full pass with baddisk’ _on the Pi_, as
requested above?
