About Samsung Data Migration MBR to GPT Cloning

Samsung Data Migration is designed by Samsung for users who want to clone HDD to Samsung SSD. It helps to transfer all the data on the old hard drive to a new Samsung SSD. What makes it most attractive is that users can go back to their previous operating system without reinstalling it. Both MBR and GPT disks are supported in Samsung Data Migration. Then, how can you achieve Samsung Data Migration MBR to GPT cloning?

Before you start cloning MBR disks to GPT disks, please pay attention to:

◈ If you are cloning an MBR system disk to GPT, make sure your current operating system is 64-bit and your computer supports UEFI boot mode.
◈ Since MBR disks support the maximum disk size of 2TB while GPT disks can grow to a very large size, there must be unallocated space on GPT disks after cloning. To make full use of the disk space, you can either create new partitions or extend the existing partitions with the unallocated space.

How to clone MBR to GPT SSD with Samsung Data Migration?

To clone MBR to GPT SSD by Samsung Data Migration, there are two things you should confirm:

◈ As Samsung Data Migration only supports Samsung SSDs listed in the User Manual, your target GPT SSD must be one of them.
◈ Samsung Data Migration requires an operating system installation on the source disk, so your source MBR disk must be the system disk.

Now I’ll show you how to clone MBR to GPT SSD with Samsung Data Migration in detail:

1. Connect Samsung SSD to your computer and make sure it can be recognized. Run Samsung Data Migration. In the “Start” page, click on Start in the bottom right hand corner.

2. You’ll see the Disk Analysis and Cloning menu then. Confirm the source and the target disk listed here and click on Start to begin the migration process.

3. Wait until the process is finished. Shut down your computer, replace the old hard drive with the new Samsung SSD and you will get the system back immediately.

Note: A difference of a few GB of data capacity between the source and the target disk is normal after cloning.

Now you see how Samsung Data Migration MBR to GPT cloning works. However, some users are confronted with Samsung Data Migration cloning failed error which is caused by dynamic source disk, instant PC recovery software installed on the system and even no specific reasons. At this time, what you need is Samsung Data Migration alternative.

Equivalent of Samsung Data Migration in MBR to GPT cloning

The prime disk cloning software, AOMEI Backupper Professional, can be the best alternative to Samsung Data Migration. It supports Windows 10/8.1/8/7/Vista/XP. With the Disk Clone feature, you can clone MBR disk to GPT SSD no matter what brand of SSD you use. What’s more, the source disk can either be the system disk or a data disk. Learn how to clone MBR to GPT via AOMEI Backupper below:

Note: Backup files on the destination SSD before cloning, because it will be overwritten during the cloning process.

Step 1. Connect the GPT SSD to your computer and make sure it is detected. Install and run AOMEI Backupper. Click “Clone” on the left pane and select “Disk Clone”.

Choose Disk Clone

Step 2. Select the MBR disk as the source disk and click “Next”.

Select MBR Disk

Step 3. Select the GPT disk as the destination disk and click “Next”.

Select GPT Disk

Step 4. Tick “SSD Alignment” to improve the performance of the destination SSD. Confirm the operation and click “Start Clone”.
