I got a private email a while ago from Thiemo Nagel claiming that some

combined with a "proof" which was plain wrong, and could easily be
disproven using basic enthropy accounting (i.e. how much information
is around to play with.)
However, it did cause me to clarify the text portion a little bit. In
particular, *in practice* in may be possible to *probabilistically*
detect multidisk corruption. Probabilistic detection means that the
detection is not guaranteed, but it can be taken advantage of
opportunistically.
If this means that there can be no false positives for multidisk
corruption but may be false negatives, fine. If it means something else,
please restate one more time.
