CMS knows about the formatted section of the disk, as Alan explained above.
However, don't get cocooned into thinking that CMS knows everything. It
certainly doesn't know that you made an error. If you went to reformat that
disk with CMS's FORMAT command, you would have destroyed not only the
intended portion (in your case 120 cylinders) but all 158 cylinders that you
defined as a size. That means that you would have reformatted the first 38
cylinders of a minidisk that follows MAINT CF1 (which is probably MAINT CF2)
and you would not know it until you IPL that system and try to access the
MAINT CF2 or do QUERY CPDISK and see that MAINT CF2 is not on the list. So,
in this respect, you *were* lucky.
