    Cannot Format HD

    I have a 4TB HD that was previously formatted that I've put into an external hd bay. When I go into Computer Management/Disk Management the hd is not listed in the top section and in the bottom section it is split into 2048 GB and 1678 GB, both "Unallocated". I want to reformat the hd into one partition but the only available option when I right click the larger partition is "New Simple Volume" and for the smaller partition there are no options available at all. Nowhere does it give me the choice to delete everything or just reformat the entire drive.

    Need to initialize it as GPT disk type with HD > 2TB:
    From Admin command prompt:
    1. diskpart
    2. list disk =====> Take a note of disk # for the 4TB HD
    3. select disk # ====> From step 2
    4. clean
    5. exit

    Open Disk Management and initialize the disk as GPT, create simple then format.
