About Convert MBR Disk to GPT Disk

Solution: if it's a data disk only, you can run MiniTool Partition wizard from within windows. It takes about 2 minutes, and is non-destructive. We have a 2TB disk for our SQL DB data storage and we need to increase this disk by 200GB only to found out that the current disk type is MBR so it has a limitation of 2TB.

Master Boot Record (MBR) and GUID Partitioning Table (GPT) are two partition styles. Even though they achieve the mutual goal of separating the information for the operating system, they are very different from one another.

These are 2 main differences between MBR disk and GPT disk:

Number of partitions: an MBR disk supports at most four primary partitions or three primary partitions and one extended partition while a GPT disk can support up to 128 partitions in Windows.
Size of partition: the size of a single partition in MBR disk can only reach 2 TB while the largest partition supported by GPT disk is 18 EB.

But these aren’t the only reasons why so many users wish to convert from MBR disk to GPT disk. One of the other amazing features the GPT disk also offers is the ability to store multiple copies of the data within the operating system.

If the data is overwritten or corrupted, the GPT disk can recover the data, so the OS will function again. In contrast, the MBR disk does not have this feature and thus unable to easily recover corrupt or overwritten data.

This explains why a growing number of users would like to convert MBR disk to GPT disk as soon as possible. But how to convert MBR disk to GPT disk without data loss? We suggest using MiniTool Partition Wizard Free Edition.
