Thanks for your response. You're correct about the bad sector warning.
So please correct me if I have some mistaken assumptions. I thought
btrfs would be tolerant of that -- if a block failed the checksum test,
it would reconstruct and remap it. (Also, I assumed that if a drive
hadn't filled its bad sector remapping table, it could handle it at the
hardware level, and SMART's warning was just that -- a warning, not a
dire pronouncement of utter unsuitability -- but that's something else.)
