Oh, I read a version of this earlier.  It was there.  I didn't reply
since I don't know an answer for you off the top of my head.  Not even
off the top of the pointiest part of my head...

This is likely to be a lame answer, meaning there's probably a much
better one somewhere, but had I enough RAM, I'd configure a huge
RAMdisk, and `dd if=/dev/hd? of=<ramdisk>`, then start searching.
Alternatives to explore might be a program, pretty low level, to
read in raw sectors, maybe write it to a file, system("perl -e ...")
to search, etc, reiteratively.

When's your deadline with this paper, anyway?
