Back in those same mid-80s I added code to the FORMAT command to provide
an 'EXTEND' option. You could create a new, larger minidisk, the first
cylinders of which were a replica of the old one. Then you could simply
FORMAT the new minidisk, specifying the EXTEND option, and it would

I understand, but given that it is something easily worked around, I don't
see it ever being done.

The allocation map like the directory is at heart just another file.

Since this *is* the Linux/390 discussion, it's fair to explain
CMS FORMAT in Linux terms. It is akin to 'mformat'

Hello,

Is there a procedure that allows me to back up a mini disk and restore to a new

Joe,
If you got DFSMS installed, the DFSMS COPY command followed by a CMS format
recomp, is a very nice and fast option to copy one minidisk to a new fresh
(unformatted) minidisk.
More convinient is of course to use a directory manager...
