  2. A message will be displayed stating that all internal data will be destroyed.
    1. Type yes and press Enter to confirm creating the GPT partition table.
  3. Type unit TiB to change the unit
  4. Type print to check the capacity
  5. Type mkpart primary 0TiB 3.64TiB (Change the capacity to yours🙂)
  6. Type q to quit
