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 .

The dump worked with the lower density device. Thanks!
