At this point the way I have dealt with it is by not deleting the recording that produced the error. If I delete it some future recording will do the same thing. I've noticed the same symptom multiple times in the last year, >10. So far not deleting that one recording seems to have contained the problem. I have a great deal of experience with computers and hard drives. All of my experience points to a bad/weak sector on the hard drive. It would be nice if they had a tool in the settings that would let you scan the drive and reallocate bad sectors.
