I suggest that the steps involving partitioning multiple drives are
prone to error.
I offer that the use sfdisk is more accurate, and user friendly.
By using sfdisk with the -d option we can get a dump of the current
partition table in a regular file,
and if needed we can restore it from that file.
Example:
| sfdisk -d /dev/sda | sfdisk /dev/sdb
This is a very simple way to duplicate the partition table from one disk to another.
