I recently had to rehouse an 8 TB drive due to damage to the micro B socket. It has only ever been one partition. Windows 8 and 10 incorrectly identify it as being split into 3 partitions. I need to effect an MBR to GPT conversion. Many methods can do this, but my choice is restricted as I don't want to lose the data.
