Lacking professional computer knowledge, I always get stuck in disk management issues. I have got a hard disk which is formatted with MBR and it is larger than 2 TB. Due to limitation of MBR, I can only use 2TB disk size. However, I would like to use the rest. Is there any way to improve the situation? Definitely, there is and converting disk to GPT without losing data is possible.
1. MBR disks only support up to 2TB partition size and support only four primary partitions. (If partition size surpasses 2TB, the start cannot be read and displayed. If more partitions are needed, users have to build a secondary structure known as extended partition, and then create logical partitions.)
2. GPT can make use of a very large size to break the 2TB limit of MBR disks and allows an almost unlimited number of partitions. (Though Windows implementation restricts the number to 128, it is completely sufficient for using.)
We have listed out the main differences between MBR disk and GPT disk. As users can see, in most cases, GPT disk is superior to MBR disk, and that is why most computer users would like to convert MBR disk to GPT disk. Well then, how to perform the operation?
Before users start to convert disk, they need to pay high attention to those items:
1. Log in as Administrator to fulfill disk conversion operation.
2. Back up the disk needing to be converted before hand, for converting the disk requires that all partitions and volumes in certain are deleted.
Solution 1. Using Disk Management tool
Firstly, right click My Computer and choose Manage > Storage > Disk Management to open the tool.
Secondly, delete all volumes on the MBR hard disk which users want to convert to GPT.
Thirdly, right click disk 2 needing to be converted and click “Convert to GPT Disk” option from pop-up menu. At this time, users can create partitions on the GPT disk.
Solution 2. Using “diskpart” command line
The following will convert disk 1 to GPT disk.
1. Open command prompt by clicking under Start > Run and typing “cmd”.
2. In the command prompt, type “diskpart” and press Enter.
3. Type “list disk” and press Enter.
4. Type “select disk X”(X represents the disk needing to be managed) and press Enter.
5. Type “detail disk” and press Enter. This will display a list of all the volumes on the selected disk. If users do not have any volumes listed, then follow step 9.
6. Type select volume Y(Y represents volume to be deleted) and press Enter.
7. Type “delete volume” and press Enter.
8. Repeat steps 6 and 7 for each volume listed in step 5 until all volumes in the chosen disk are deleted.
9. Type “select disk 2” and press Enter.
10. Type “convert GPT” and press Enter.
11. Type “exit” and press Enter.
The detailed operations to perform MBR disk conversion are demonstrated as above. As presented, using Disk Management tool and “Diskpart” command require deleting volumes, so they are quite risky. Moreover, low operability is also a leading concern. In such cases, users can adopt third-party server partition management software to accomplish certain operation easily. Here, highly competent MiniTool Partition Wizard Server Edition is of high recommendation.
Following those steps, users can easily convert MBR disk to GPT disk:
1. Download the server partition magic and then install it on computer. After that, launch the software to open its main interface.
2. Choose the disk to be managed and click “Convert MBR Disk to GPT Disk” from left action panel.
3. After clicking “Apply” button in the upper left corner, the chosen MBR disk has been successfully converted to GPT disk.
MiniTool Partition Wizard has successfully converted MBR disk to GPT disk within three steps. If users also need to perform certain operation, hurry to experience the magic of the software.
