We add partition labels to partitions on a USB disk. We saw that different filesystems use different label commands. For example, We used "sudo fatlabel /dev/sdb1 PART1_FAT16" to rename our FAT16 filesystem and we used "sudo e2label /dev/sdb2 PART2_EXT4" to update an EXT4 filesystem partition. The commands shown in the video are not the only ways to update a partition label, for example to update the EXT4 partition, we could also have used the command "sudo tune2fs /dev/sdb2 PART2_EXT4" which was not shown in the video.
