Before we talk about the way to convert MBR hard disk to GPT, let’s just imagine that there is a situation in which users just buy a new 3 TB of hard disk. Since the new disk size is larger than 2 TB, if users choose to initialize the disk to MBR, then the exceeded 1 TB of capacity will be wasted. Why? The reason is that MBR disk can support at most 2 TB of hard disk. If a certain disk size is lager than 2 TB, the extra capacity can’t be identified or used. However, we know that GPT disk supports at most 18 EB of hard disk capacity. So, when we initialize a hard disk whose capacity is larger than 2 TB, we had better try to initialize it to GPT disk in order to take full advantage of hard disk space.
What if users have initialized a 3 TB of disk to MBR? Users don’t need to worry about wasting disk space now, because they can change MBR disk to GPT to solve this problem with ease. Then how to change disk type successfully? Two ways to convert MBR hard disk to GPT will be displayed in the following content.
Note: If users have saved data to the certain disk, they had better make a data backup before performing all operations in order to avoid data loss.
Step 1, after users enter the window of “Administrator: Command Prompt”, they need to input “diskpart”, press “Enter”, enter “diskpart help” and press “Enter” again.
Step 2, enter “list disk”, press “Enter”, and then input “select disk 4” (the target MBR disk) and also press “Enter”.
Step 3, input “clean” and press “Enter” to delete all partitions on the target disk.
Step 4, enter “convert gpt” and press “Enter” to start to convert MBR hard disk to GPT.
This is the end of the first way to change disk type. Here we will show users the second way. This way is to change MBR disk to GPT with third party tool – MiniTool Partition Wizard.
Step 1, choose the target disk in the main interface of this partition software, click “Disk” from menu bar and choose “Convert MBR Disk to GPT Disk” option from the drop-down list.
Step 2, click “Apply” and choose “Yes” to perform the pending changes.
Users can choose a way they like from introduced two different ways to convert MBR hard disk to GPT. If they want to get the software, they can visit the certain web page.
