[Bug 1084248] [NEW] cfdisk doesn't like 3TB disk

[Thue Janus Kristensen]

Public bug reported:

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.
