Title:
  cfdisk doesn't like 3TB disk

Status in “util-linux” package in Ubuntu:
  Triaged

Bug description:
  I tried creating a 3TB (minus 50GB) partition on a new blank 3TB hard
  disk. I created it as a primary partition from the start of the disk.
  But the created partition was only on 721863828 (721GiB). Deleting it
  and then trying again (this time with one primary partition filling
  the whole disk) gave the same problem.

  Trying with fdisk worked better, but still only created a 2TB
  partition when I asked for a 3TB partition. cfdisk could no longer
  open the disk!

  Using parted worked: http://icesquare.com/wordpress/how-to-install-a
  -3tb-drive-on-linux/

  While I (now) understand that this is probably because of parted's
  support for gpt, I still think cfdisk and fdisk were not as helpful as
  they should have been. They should have returned an error message when
  trying to create impossible partitions, instead of silently creating
  the wrong partitions.
