Dan,
In fairness to both my original correspondent, and Christopher, I do not
think that the docs have any warning that this would happen. If anyone can
find a KB article or anything else that does warn of it, then I would be
very grateful to know of it.
And if Apple was aware of this, why did they not include a check to see
whether Tiger was about to try (inevitably fatally) to rebuild a Panther
RAIDset, and then warn the user that the result would be unrecoverable
before making it so?
Howard.
