Testdisk looks powerful, and might do the job. Now how to figure out how to use it with no prior experience and without further risk to the clobbered data?

+1 Much less hackish and a better solution for binary files than grep/perl.

Whew, turns out I had a copy of my bacon on a laptop that I took in for repair, and just got back. The drive I was going to try testdisk on, having very little newer stuff, is now safe to toy with. I will experiment with testdisk for educational purposes.
