Disks aren't immune to the ever-present cycle of technological improvement. Following a long period of popularity for master boot record (MBR) partitions, the next generation of disks will use the GPT partition format instead.

Disk cloning is well-established, and GPT disks can be copied without issues. In this piece, we'll explain how this works and walk you through implementing it with straightforward, professional software.

Learn about GPT Disk: What is it?

Disks with a partition format called GUID Partition Table (GPT) have recently superseded the archaic Master Boot Record (MBR) standard, which goes back to 1983. There are many benefits to using a GPT drive.

Backup data on GPT disks is efficiently dispersed over all partitions instead of MBR disks, where it is stored centrally. Since GPT disks can use data from another partition to restore themselves if one partition becomes corrupted, this greatly improves the likelihood of data recovery.

Large storage unit capacity; MBR disks' upper limit of 2 terabytes is based on the fact that each storage sector can only be up to 32 bits. However, GPT drives have a sector size limit of 64 bits, translating to more than 9 ZB (Zettabytes) or almost a billion Terabytes.

GPT Advantages and Features:

Windows computers can use either the GUID Partition Table (GPT) or the Master Boot Record (MBR) to define a hard disk drive (HDD) or solid-state drive (SSD) to store data, install software, and install and upgrade operating systems. In addition, GPT disks offer some special characteristics that MBR drives do not.

GUID Partition Table Characteristics:

  • Back up massive disk space, from 3 to 8 exabytes.
  • Compatibility with Mac OS X and Windows is supported.
  • Unlike MBR, it can handle more than 4 primary partitions and volumes of less than 2TB in size.
  • Protect sensitive information with CRC values, allowing automatic data recovery in the event of corruption.

Main challenges of cloning GPT HDD

Drive partitioning information can be stored in the Master Boot Record (MBR) or the more modern GUID Partition Table (GPT). Like many other users, you may experience boot difficulties after copying an HDD to an SSD if you don't notice the partition style issue. Cloning a GPT hard drive to an identical GPT solid-state drive is simple, with only minor complications. Cloning a GPT hard drive to an MBR solid-state drive is a major challenge. Because of the dissimilarity between the two partitioning methods, the cloning process is more prone to mistakes.

Clone GPT HDD to SSD securely

If the target SSD is a GPT drive, you'll need to delete redundant data, resize partitions, or use cloning software that can handle disks of varying sizes. You may encounter issues such as the destination SSD being physically smaller than the originating HDD.

However, if the destination disk is an MBR SSD, you may need extra steps. It is standard practice first to convert a disk from MBR to GPT to erase all volumes on the MBR disk. Another option is to utilize a reliable program that allows for direct cloning of GPT to MBR, after which the boot mode can be switched from UEFI to classic BIOS.

Since Windows doesn't have this functionality, you'll need third-party disk cloning software to copy your hard drive. Follow the steps below to clone GPT disk to another disk.

Step 1. Download and install a disk cloning program - DoYourClone. Then open it on your Windows PC.

FAQs about GPT disk and cloning GPT disk

1. How to Check if a Disk Partition is GPT or MBR in Windows?

So, why is it crucial to become familiar with the disk partition style of the hard drive or SSD in a Windows PC? If you know the sort of disk you're working with, knowing the disk partition table will help you avoid the following issues quickly and easily:

  • Due to the incompatibility of the HDD/SSD, the operating system cannot be migrated.
  • The OS on a cloned SSD won't load because the disk format is incompatible with the boot procedure.
  • No way to make a partition on a 6TB disk that's 2TB or larger.
  • A hard drive can only have four primary partitions.

To view the disk partition table on a Windows PC, simply open Disk Management by following these steps:

  • First, select "Disk Management" from the context menu when right-clicking the Windows icon.
  • Second, right-click the disk and select "Properties" to inspect its partitioning method.
  • To check if your disk is Master Boot Record (MBR) or GUID Partition Table (GPT), navigate to the Volumes tab and look under Partition style.

2. How to clone a GPT disk to another disk?

You can use disk cloning program, such as DoYourClone to help you quickly clone GPT disk to another HDD or SSD. This software also supports to create bootable clone for your Windows PC or Mac.


As you can see, GPT drives can hold a tremendous amount of data, which can be crucial for the user. You can't afford to lose these data, and if you have to relocate them and reload your programs every time you reinstall Windows 10/11, it will be a huge hassle. Disk cloning is a time-saving method that also ensures the security of your data.
