I had the exact same problem with an IBM DeskStor 40G drive a few weeks
ago.

I get this same error when walking a 30G partition on the IBM drive.  To
temporarily fix it, I moved as much data as I could to a smaller
partition on the same drive and unmounted this partition (to prevent
cron from doing its daily ``find'' process and walking the bad
filesystem).  On a side note, this is why the rt.fm openbsd
anoncvs/ftp/http mirrors have been down recently.

When I get some time, I'm going to try creating a new filesystem on it
and see if the errors still exist.  If they do, I'll probably have to
end up buying a new drive.  I don't know what else to tell you, though.
