Lines which have first column starting with letter s (because that's how drives typically are named) and ending with a number (which represent partitions). What exactly is happening there is that we're listing all the

Sector size (logical/physical): 512 bytes / 512 bytes To address the listing of the unmounted partitions part, there are several ways - lsblk, fdisk, parted, blkid.

Volume could not be unmounted.
