Partitions and disk layout

  • The cylinders define partition boundaries. The sectors define data blocks.

  • To see the block devices (drives and partitions) on the desktop:
    lsblk -f
    sudo fdisk -l  | grep sd

  • Our desktops have two drives, /dev/sda and /dev/sdb.

  • To partition a drive, we can use command fdisk

  • For hard drives > 2TB capacity, one should use gdisk or parted commands.
