Just a gloss on part of Dieter's excellent advice:

Derek's .fs file is over 5GB.  People tend to believe that
fsrecover.py truncates a damaged .fs, but that's just because most
people run it immediately after a power outage, or other circumstance
in which just the tail end of the .fs is damaged.  Then fsrecover does
truncate it.

But fsrecover *tries* to be smarter than that:  it looks ahead after
each damaged area it finds, for the first place it can "synch up"
again.  So it's possible that fsrecover will recover nearly the entire
5GB here; it's also possible that it will only recover 475MB.

That's certain, since fsrecover works by throwing bytes away.  What's
impossible to guess is whether it will throw away anything the app
still needs.  If the app is running is OK, the odds of success are
decent.
