You should let your disk deal with it.
Try booting single user and:
dd if=/dev/ad0 of=/dev/null bs=1m
and see how much damage there actually is.
If there is much damage, you may want to use
Poul-Henning Kamp | UNIX since Zilog Zeus 3.20
phk at FreeBSD.ORG | TCP/IP since RFC 956
FreeBSD committer | BSD since 4.3-tahoe
Never attribute to malice what can adequately be explained by incompetence.
