Please describe the problem:
this bug derived from 524948, submitted on developer request.
gparted displays information for my disk unit, listing the entire device
as smaller than what is listed for a partition, by >5000 sectors.
my guess is that this has to do with the device being a 2 TiB one, and the use of GPT for the device label.

original bug report:   

Size: 2.00TiB
Path: /dev/sdd

DiskLabelType: gpt
Heads:   255
Sectors: 63
Cylinders: 267349
Total Sectors: 4294961685

when I ask for information about the existing partition created with parted, it
has a warning triangle (unable to detect file system.)   right click for
information gives /dev/sdd1:
  un-known filesystem type.
  First sector: 34
  Last Sector 4294967126
  Total Sectors: 4294967093

Please note that it reports 5611 more sectors in the partition than in
the whole devices 'Total Sectors'.

If, in the GUI I then delete, and re-create with 'round to cylinders'
unchecked,
it creates the partition with a size -512.00B  when I click apply, it complains
about an empty partition.

I exit gparted, and re-created the partition with parted via:
mkpart ext2 0 100%
quit

and then re-mounted the file system with no data loss.



Steps to reproduce:
1. get a really large disk
2. create a single partition for the whole disk
3. fire up gparted, look at the 'information' for the device and the partition. compare the numbers.



Actual results:
the partition size is smaller than the device size, when this is done on my drobo storage unit.


Expected results:
I would expect partition size <= device size.


Does this happen every time?
yes.  done several times, repeatable.
