Can you talk more about it? So an issue during shutdown running from the external drive destroyed a partition of a internal drive?

I can see power issues corrupting the external drive (and I can live with that), but I'm wondering what went wrong in your case.

I'm not sure running the whole thing from a live-boot (which is kind of the point of the topic, different from a external installation which is what I use) would have prevented anything.
