For the first problem, the invalid starting block for an LDL disk,
the failure would involve reporting an incorrect starting position,
an incorrect partition size, and not
recognizing any file system which might be on it, since it is
not pointing to the superblock. This occurs only on LDL disks
with a block size other than 4096. With the patch, the partition size
will be correct, the starting position will be correct,
and it will recognize the file system built on the
partition, if there is one. The command would be something like
parted /dev/dasda print
For the second problem, lack of recognition of CMS minidisks, the
above command will report
Error: /dev/dasda: unrecognised disk label
if the patch is not on. If the patch is on, it will generate the
normal expected output for the above command.
