My company has been having the same thing happen to some users. We have not been able to recover the data so far, but are trying to get support on it.
To prevent this in future, the new version, 184.108.40.206, seems to resolve this issue from occurring. When it comes up with that message and you do a scan and fix, it seems to go through and not detect or fix anything, and then unfalgs it as corrupt. Or at least, that is the behaviour so far with the new version. No trying to recover sectors, no found.xxx files, just unflags it and then acts normal again.
Would love to know if there is a way to recover the found.xxx files though, so please post if you find anything!
