Linux <code>sfdisk</code> (on a [[SystemRescueCD]]) is able to save a backup of the primary and extended partition table. It creates a file that can be read in a text editor, or this file can be used by sfdisk to restore the primary/extended partition table. An example command to back up the partition table is <code>sfdisk -d /dev/hda > hda.out</code> and to restore is <code>sfdisk /dev/hda < hda.out</code>. It is possible to copy the partition table from one disk to another this way, useful for setting up mirroring, but sfdisk executes the command without prompting/warnings using <code>sfdisk -d /dev/sda | sfdisk /dev/sdb</code>.<ref name="Linux_MAN_sfdisk"/>
