    convert it to GPT disk. MBR disks can not be larger than 2TB

    cengizhan is correct. If you have installed as legacy/mbr, the max partition size is 2tb with the rest unusable...

    There is no need Wipe it. Just convert to GPT... Without losing any data. But beware, if you reverse it, you will lose it..

    Good luck.
