I have a 3Tb seagate hdd, and i mainly want to use it for storage.. but it shows up in as 8.00Gb Healthy, 2040.00 unallocate, 746.56 unallocated.. i want to use at the most majority of the 3tb but i cant change it, can any one help... the convert to gpt is greyed, and the only thing that is available is to make the 2040.00 a simple volume, when i try to right click the 746.56 eveything is greyed.. when i did make it a simple volume i still dont have the option of using all of my space..
