The ext3 implementation makes is basically impossible to recover deleted
files, unless you search the whole disk looking for the data that you
want to recover.  This is an implementation detail for truncate, and may
concievably be fixed (I've discussed an improvement to do this several
times), but nobody has ever worked on it.
