My worry is that the "log uuid" was neither zeros nor the proper UUID; it was something else. So it wasn't bad, unreadable sectors which got filled in with zeros by ddrescue, it was apparently some random data coughed up by the enclosure for some unknown reason. If it did that to the log, it may well have done that to many other parts of the filesystem as well. -Eric
