| 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 |
| 189 | | root@OpenWrt:/# df -h |
