Partitions

Some CLI software:

• fdisk
• sfdisk
• parted

Some examples:

$ sudo fdisk -l /dev/sda
$ sudo fdisk -l -u /dev/sda                         # Use sector as unit
$ sudo parted -l /dev/sda                           # Don't forget the sudo
$ sudo parted /dev/sda print
$ sudo parted /dev/sda unit cyl print               # Print partition table using cylinder as unit
$ sudo parted /dev/sda unit s print                 # Print partition table using sector as unit (more accurate)
$ sudo sfdisk -l -uS /dev/sda                       # Idem
$ sudo sfdisk -d /dev/sda >sda-sfidk.dump           # Dump partition in a format that can be understood by sfdisk
$ sudo sfdisk /dev/sda <sda-sfdisk.dump
$ sudo dd if=/dev/sda of=sda.mbr bs=512 count=1     # Save the MBR
