I have been at this for a month time for some help. I have a 3tb seagate hdd i am trying to format as 1 big storage drive. I am trying to convert to gpt using aomei. problem is the 3tb drive is showing up as 2 disks (disk 2 and disk 4)insted of different partitions on the same disk. The small 746gb is showing as gpt and the 2tb showing as mbr. there is no option to convert to gpt on aomei or windows disk management. what the heck is going on?
