For me the obvious think was > that the system complains when trying bioctl -d sd0. Perhaps. But that would require not-trivial WORK, maybe a LOT, which someone would have to DO, probably for FREE. I suspect detaching a running encrypted root disk is somewhat uncharted territory. In a perfect world the same command might've offered a "failsafe" mechanism and performed logout, shutdown, umount and sync and whatnot in the case of an affirmative response, but not in ours. Such a perfect world might not even be preferable given how much added code complexity and size such "failsafe" mechanisms could involve. For now, consider yourself lucky to have recovered your data. That is the most important thing and I'm happy on your behalf to hear that you managed so. Regards
