How to create a partition in unallocated area?

Question

western digital

I bought a new HDD 3TB, Western Digital Red, WD30EFRX. Opening the disk using disk management, it was reflected as 2 unallocated areas: 1800 GB and 800 GB. A partition was created in the 1.8 TB area and formatted without problems, and the second unallocated area was 800 GB neither acronics nor disk management could create a partition. What could be the reason and how to overcome it?

Answer 1

On the WD website they write that partitions need to be created in GPT and not MBR

BootIce is recommended on the forums but this is at your risk, I did not use it myself

Answer 2
