File System errors

[Ross Penner]

I recently had my system freeze so I had to manually restart it. I was
worried that there would be some problems with the filesystem so I
looked into the matter and discovered the utility fsck. I ran this as
root and I got the following:

It seems to my unexperienced eye that their are problems in some of
the filesystems, but they arn't being resolved. I tried running fsck
-y  and nothing changed. What am I doing wrong? How can I resolve
these issues? Thanks for any help you can offer.
