Thank you for the quick reply, Otto. I overlooked that option, which is kind of funny, I know it's saved my butt before. Anyway, I tried using alternate superblocks, several of them (picked at random from various spots within the ones named by newfs -N), and fsck is still dying with the same error message.
I have been able to mount the filesystem read-only. I'm not sure what else to do at this point. I feel like I'm overlooking something really obvious and foolish, but I can't quite put my finger on it. Anybody have any other ideas?
