mounting a ext2fs part and need fsck_ext2fs

[Kevin L. Kane]

Im trying to mount a ext2fs partition from dragonfly but I keep
getting a error like this:

mount_ext2fs: /dev/ad2s1: Invalid argument

There wasnt much info about why this happens, I did find a post
somewhere that said if its a ext3 part that got shutdown improper you
need to fsck first before mounting it.

Is there another issue that it might be? And can anyone point me at a
place to get fsck_ext2fs for my dfly machine that wont be a complete
hack :).

Thanks,
Kevink
