Run fsck a couple of times, to see if it goes away. Otherwise, you'll
have to walk the ext2fs structures yourself using the tools that come
with e2fs tools (or something which sounds like it).

In general, it is not worth the hassle, if you don't have really important
data in there.

If you're in a situation where such crashes are frequent, you may want
to run your fs in sync mode at lower performance, but higher safety.
