How to Convert MBR to GPT – MBR or GPT.

I will add more information to this section on HDD’s in this area formation.

I got some new HDD’s that needs to go into a Desktop, however, to get full capacity of the Labeled 12TB HDD it needs to be formatted correctly.

MBR wasn’t letting the HDD show the higher capacity this is where the GPT fixed this limitation, after following the video below it all turned out just fine.

Plese do remember if you’re converting any HDD using formatting process do backup your data always onto external HDD’s.

Step (1) You need to get to the administrator command prompt.

Goto – Hover your mouse over the Windows Start Menu, – Right Click on it, – Choose Windows Terminal (Admin).

Step (1 B)

KEYBOARD SHORTCUT

Windows Key + R, type cmd in the box.

Step (2)
In command prompt type: diskpart

Step (3)
Then when moves into DISKPART> type: list disk

It will show all the HDD’s that are MBR or GPT, the * tells you if you HDD is already GPT no * = to MBR.

DISKPART will list

Disk ###    Status          Size          Free         Dyn      Gpt
———–    ———–        ———       ———      ——    ——
Disk 0         Online       476 GB      1024 KB                     *

Disk 1         Online       476 GB      1024 KB                     *

Disk 2         Online          28GB           28 KB

Step (4)

To select the selected disk type in select disk 2 and hit enter.
DISKPART> SELECT DISK 2

You should get the message.

DISK 2 IS NOW THE SLECTED DISK.

Step (5)

Now that the disk is selected it needs to be formatted, type clean and hit enter.

DISKPART> CLEAN

DiskPart succeeded in cleaning the disk.

Step (6)

Now to covert the disk to Gpt

DISKPART>CONVERT GPT

Diskpart successfully converted the selected disk to Gpt format.

Step (7)

To check your disks to make sure it was converted correctly type the following below.

DISKPART>LIST DISK

The disks information list should show that the HDD that was MBR is now GPT.

Disk ###    Status          Size          Free         Dyn      Gpt
———–    ———-        ———       ———      ——    ——
Disk 0         Online      476 GB    1024 KB                     *

Disk 1         Online      476 GB    1024 KB                     *

Disk 2         Online         28GB         28 KB                     *

This is what fixed all my HDD’s to be usable after buying them new.
