fsck? problems with machine

[Ben Haysom]

Hi

I emailed a while back.
My machine reboots itself during a portupgrade -a.
I was advised to test the CPU and memory, which I have done with
cpburn and memtest respectively. They both seem fine.
I've re-run fsck, but I don't really understand the results, and I
can't find an explanation anywhere. I'm now pretty sure it's the HD at
fault... would explain some dodgy behaviour in the past too.
Help?
Ben.
