Given that, I would try to make a dump(8) of it. If dump dies on a particular file, try to exclude that file from the dump either by rm-ing it or setting a nodump flag and try again. You may not actually be able to do the rm or nodump flag though if you cannot mount it with write permission. You might be able to force it mounted without doing the fsck in single user. Note that tar allows you to specify exclusions. I usually don't suggest using tar for mass moves because it has weaknesses with hard links and might also not transfer flags and permissions correctly. But, if tar is what it takes, then use it.
