Slightly orthogonal, and I know it's been discussed before, but I think
it would be worth considering just blacklisting all firmware revs for
this model.

There were several firmware releases for these drives. And while it's
conceivable that post-2BA30001 may fix the issues, I think it's safe to
say that all the intermediate releases between the two we have are
equally broken.
