    We were having the same problem.  It is a bogus error.  If data 
address 1 was bad you would not be able to read the disk.
Apollo sent us a patch tape that contains a new version of invol.
It seems to have taken care of the problem (so far).  Ask your
sales rep for the version of invol that was last modified 11-30-87.
                                                                
Best of luck,
rye.
