Various people have asked for a method to allow them to mark bad sectors
off on the AT hard disk (the CMIs seem to develop them like a spreading
disease).  The Norton Utilities 3.x includes a program called DISKTEST
(or DT) which does this.  You can test all your sectors or files by running
it and if it finds unallocated bad sectors it will ask if you want to mark
them off.  Only problem is that it does this only by read-testing (obvious
since it doesn't want to destroy anything) and so often will not find
something that is a problem.  Also doesn't play with the retry on error
handler so sometimes things get by and you have to run it a few times in
a row.  Would be nice if you could set the 'sensitivity' to change the
number of retries which would cause an error to be noticed and if it would
also do write tests on unallocated sectors.  Anyway, for what its worth
and given that I don't like the rest of the package very much, this program
has saved me a lot of grief with my CMI drive.
