Public bug reported:
The Disk Utility cannot edit partitions (create, delete, LUKS) on GPT-
based drives with a size bigger than MBR-based drives would support.
I have a 4TB WD My Book 1140.1016 that requires a GPT partition table
because it's 4GB, beyond MBR (MSDOS) limits. When I create a GPT
partition table, I cannot add or remove partitions from the Disk Utility
with this output:
Error erasing: helper exited with exit code 1: In part_del_partition:
device_file=/dev/sdb, offset=3145729048576
Entering MS-DOS parser (offset=0, size=4000752599040)
