Change MBR to GPT on external hard drive with data:

I found a way for the internal one here. However the External drive is a Data drive only, I dont't need to care about any bootloaders etc. So is there an easy way to do it? It is a 3TB external drive, the setup in Gpartet looks like that:

| 8MB unallocated space|1,36TB ntfs with ca 300GB of data|1,36 of unallocated space|

Note: Like all operations involving partition manipulation, the below procedure carries some risk, and you are strongly advised to backup any critical data beforehand.

If this is a data drive only, I believe the start/end margins are sufficient, and a simple sudo gdisk /dev/sdX (follow steps) should do the job, converting the MBR to a GPT.
