    Format mbr external drive to gpt


    I was recently instructed how to format a GPT external drive to MBR.It was 4 terabytes and now is only 2 terabytes.I understand why because it was explained on this site.What I would like to know is can I format it back to MBR so I can get
    the 4 terabytes back.Hope I explained that right,thank-you Tony.

    Have you went into disk management and checked to see if the entire Hard disk is allocated? If all 4 tb isn't showing, then the rest of the disk hasn't been allocated and formatted.
