    132 An example is provided below:
    133 1. Partition the drive using {{{fdisk}}}. Example shown below.
    134 {{{#!bash
    135 > fdisk /dev/sda

    177 2. Format the drive using
    178 {{{#!bash
    179 mkfs.ext4 /dev/sda1
    180 }}}
    181 3. Mount the drive
    182 {{{#!bash

    187 4. Verify disk size (see {{{/dev/sda1}}} as the last item in the list below)
    188 {{{#!bash
