I think the answer is to not validate the disk.  A long time ago
(in a galaxy far, far away...  no, No.... It was in Detroit.) I
wrote a program that would UNvalidate a disk.  It would read the
whole disk and allocate any sector that contained data.  This is
a useful thing if you have done a validation in error or want to
save a "Splat" file from destruction.  Actually, I wanted to be
able to store other adventure games on my Zork disks, it worked
fine for this.
