    Good luck!  I've been down this road before and symbolics doesn't let
    out their disk formatting software (unless they've drastically changed
    policy recently).  So, symbolics users have to pay double for their
    disks.  symbolics ought to get out of the hardware business.

Actually, they will sell you the initial FLOD image tape which they will
construct for your disk, this may save you a little money (At least, they
did this for Eagles).

If you look at one of your existing image tapes, you will discover it is in
a very simple format, which you can duplicate yourself without much effort.
The only real problem is translation of the info the disk manuf. gives you
to the actual block on the disk, since the bad byte may be in a header, a
gap, etc. so you have to know about the nitty gritty formatting on the
specific disk type involved. (on the other hand, we run 2 eagles with no bad
block info at all and have very few problems; fix-fep-block is usually
sufficient on the rare occasion a real bad block is found.)
