Running single user starts with the slices unmounted, that is the preferable 
way to run fsck manually. If you are answering yes to those questions and it 
doesn't fix things, could be your HD is failing. Search the mailing list and 
Google. There was an extensive thread on a similar problem a couple of months 
ago. I had a problem like yours a couple of years ago and ended up creating 
new filesystems and restoring from backup. You may be able to mount read only 
and salvage the data if you don't have backups. But, do a search first, this 
comes up from time to time.

BTW, please don't top post.
