The maximum size for a  Master Boot Record hard disk is 2TB. So, for a
2TB drive, so long as your PC has UEFI firmware instead of a BIOS, the
standard recommendation is to use GUID partitioning, A.K.A. a GPT --
GUID Partition Table -- instead of the old MBR.

This means no more primary/extended/logical partitions. They are a
peculiarity of MBR and are now a legacy feature.

Check if you have UEFI. If you do, use GPT. Then there is no more
primary/secondary/extended/logical difference. There are just up to
128 partitions.
