Problem with possible hdd crash

[Harman]

I installed Fbsd 6.0 a few days ago. I had X running one day and I
come back to it and move my mouse a bit and my comp freezes up and the
screen has some fragmentation lines on it. I do a hard reboot and I
find that the image is very distorted, including the manufacturer
before the bootloader. The distorted text was only the first reboot
after this happened, however. I boot fbsd and I get some weird errors
everytime:

fsck: exec fsck_msdos for /dev/ad1s2 in /sbin:/usr/sbin: No such file
or directory
fsck: exec fsck_msdos for /dev/ad1s2 in /sbin:/usr/sbin: No such file
or directory
THE FOLLOWING FILE SYSTEM HAD AN UNEXPECTED INCONSISTENCY:
              msdos: /dev/ad1s2 (/media)
Unknown error; help!
init: /bin/sh on /etc/rc terminated abnormally, going to single user mode

Now.. when I go into single user mode, no command seems to work
besides cd and ls. I've checked this out with a linux live cd and the
dir on this fs are all named wrongly with most having an asterisk in
the middle of them, and some just missing alot of what they're named.

I'd like to know what this possibly could have been, and how I can
mount the fbsd fs from a live cd to get some config files off of it to
make a reinstall easier, and see if I can maybe fix this by removing 
/dev/ad1s2 from my fstab. I did some stupid things with my X packages
recently and uninstalled all of them, and then had to pkg_add all of
them back, I was thinking this *might* have had something to do with
it.
