Well, I have _something_. It's called 'fcheck', not 'fsck', but it looks like
what we're talking about - maybe it was originally named, or renamed, to be in
the same series as {d,i,n}check? But it does have the upper-case error
messages... :-) Anyway, here it is:

  http://ana-3.lcs.mit.edu/~jnc/tech/unix/s1/fcheck.c
  http://ana-3.lcs.mit.edu/~jnc/tech/unix/man8/fcheck.8

Interestingly, the man page for it makes reference to a 'check' command, which
I didn't recall at all; here it is:

  http://ana-3.lcs.mit.edu/~jnc/tech/unix/s1/check.c
  http://ana-3.lcs.mit.edu/~jnc/tech/unix/man8/check.8

for those who are interested.

I think most of the Unix stuff we got from Bell (e.g. the OS, which is clearly
PWB1, not V6) came from someone who was in a Scout unit there in high school,
of all bizarre connections! ISTR this came the same way, but maybe I'm wrong.
It definitely arrived later than the OS - we'd be using icheck/dcheck for
quite a while before it arrived - so maybe it was another channel?

The only thing that for sure (that I recall) that didn't come this way was
Emacs. Since the author had been a grad student in our group at MIT, I think
you all can guess how we got that!
