[comp.bugs.2bsd] "this should not happen" from dump

jwp@larry.UUCP (Jeffrey W Percival) (03/11/89)

I was doing an epochdump on my 11/70 (2.8BSD), and got an error message
that said "bread: this should not happen" along with some numbers
(block 0, etc).

What causes such a message?  I gather from the message that
the dump program is astonished.

The message you got means that you have a disk problem.  It may be a bad
spot on the disk.  If that is the case, you can use prep -a to get rid
of that bad block.  (find out what you are getting rid of first, so you
can restore it later).  If it is more than a bad block , you may need to re-
initialize the disk, and start over.  In a worse case you may need to 
replace the entire drive.
