I am trying to digest the procedure.
Forgive me if I am a little slow, but I want to be sure to do it right.
1. this procedure requres that both diisks be identical... ?? This is
not always possible... I'm not sure I have that possibility at the
moment and I don't want to empty other disks from other machines.
2. I am trying to under stand if the procedure is to be done from the
active disk, say ad4 and the idea is to copy ad4 to say ad6? Or should I
be running on a third disk, say ad12 and be copying ad4 to ad6?
