Well, I tried mounting the CD and typing the above move command, and I
did get the man pages and info explorer stuff back.  However, I still
don't think all of it is on the CD.  The files from the install tapes
add up this way (the directory is /usr/lpp/info/En_US):

   2436    ./educ
   56      ./exer
   32048   ./prog
   2644    ./aixmin
   2568    ./nav
   28404   ./aix
   68160   .

With the CD mounted, the same directory looks like this:

   8041    ./aix
   615     ./educ
   11      ./exer
   587     ./fortran
   5498    ./graph
   2698    ./hardware
   643     ./nav
   774     ./pascal
   10830   ./prog
   29697   .

It looks like I'm missing things with the CD.

That did help.  The dump worked with the lower density device.  Thanks!
