what happens when you are in that directory and just say:

Also, what happens when you say:
  df .

/dev/sdb2            960404324    206380 960197944   0% /mnt/HD_b2

And what is the output of:
  pwd

just returns the directory path

Your dmesg output indicates that you are mounting each filesystem twice.
I don't think that is usual, but I'm not sure how it would cause this problem.

I forgot I changed it from Raid 1 to separate drives, would that explain this occurance?

I think I figured it out. I followed the instructions at http://www.inreto.de/dns323/fsck/ and when e2fsck ran it identified and deleted those files for me. Something about clearing inodes.

I am still curious why my box is apparently mounting my filesystems twice.

Here is the output of mtab

./mtab: line 1: %root%: not found
./mtab: line 2: /dev/ram0: Permission denied
./mtab: line 3: proc: not found
./mtab: line 4: /image.cfs: Text file busy
./mtab: line 5: /dev/sda2: Permission denied

./mtab: line 7: /dev/sda4: Permission denied
./mtab: line 8: /dev/sdb4: Permission denied
./mtab: line 9: none: not found

I don't know if the multiple mounts have to do with corruption as I think e2fsck fixed that and it still appears to be doing it.  The e2fsck appears to have got rid of the warnings at the end of dmesg although there is still a mention at the end of "No journal on filesystem ..." is that something to be concerned with?

Ok, thanks for the info.
