The header files, show layout and hint at the way they are marked, and hex dumps of several directories should catch one. To create one, create long file names in a directory until it spills over to two blocks (you can see it by doing an "ls -ld ."), create one more, then delete the one previous (it will be the first entry in the block) and look how it coelesces. Hey! I just thought of a shortcut: I believe the NetBSD port to Sun can mount Sun disks, if you wanted to look at that, and then the only thing to deal with would be byte order.
