How do I clone a hard drive with multiple partitions?

Hi, I'm looking forward to buy Samsung SSD 850 EVO 250GB. Right now I have Western Digital Caviar Black 1TB, with two partitions, 1 partition is Windows 10 (585GB size, 109GB used) and the other partition is blank (345GB in size). I've heard about Samsung Data Migration and I've read the user guide but it doesn't mention about cloning from target that has 2 partitions to SSD with 1 partition. Is it possible?

Why do you need to clone multiple partitions?

Most of us have at least two partitions on our computers, one for OS and one for data. Some users even have different partitions for different categories of data, such as one partition for game data.

With more and more data saved on the computer, it works slower and slower. You may feel the urge to speed up your computer, so you consider replacing HDD with SSD. You can imagine how toilsome it is to reinstall OS, create new partitions and copy files manually to the new SSD. Is there a simple way to finish the task? Cloning multiple partitions on the old hard drive can be the answer.

Step 2. Click “Clone” on the left pane and select “Disk Clone”.

Disk Clone

Tip: The Standard edition only supports cloning disks (containing OS) from MBR to MBR. If you want to clone system disk from GPT to GPT or between MBR and GPT, please use the advanced version, such as AOMEI Backupper Professional.

❕ Both MBR and GPT are two different disk types for data storage. And you can check its disk properties in Disk Management. The overall steps are below:

  • Press Win + R to open the Run window. Then, type diskmgmt.msc and hit OK to open disk management.
  • Then, right-click the disk you want to clone and select Properties in the pop-up window.
  • In the Properties window, select the Volume tab and confirm the partition style. It can be MBR (Master Boot Record) or GPT (GUID Partition Table).

Disk Partition Style

  • Similarly, check the disk partition tyle of the destination disk. If it is still MBR, you can replace multiple partitions in Samsung disk for free. 

Step 3. Select the current hard drive as the source disk and click “Next”.

Select Source Disk

Step 4. Select the Samsung SSD as the destination disk and click “Next”.

Select Destination Disk

Step 5. Tick “SSD Alignment” to use 4K partition alignment to optimize SSD performance. Confirm the operation and click “Start Clone”.

Start Clone

Note: If you tick the “Sector by sector clone” option, AOMEI Backupper will clone every sector on your old hard drive whether it is used or not, which will take more time and occupy more storage space. You can also use “Edit Partitions” to adjust partition size and convert disk type on the destination disk after upgrading to higher editions. 

​​​​​​​ BTW you cannot use them at the same time. If the target disk is larger or it has different disk type, I'll use the premium feature - Edit Partitions without a doubt. 

  • Copy without resizing partitions: It will not resize the partition size.
  • Add unused space to all partitions: It will reallocate the unallocated space to each partition of the target disk, appropriate for the disk size.
  • Manually adjust partition size: It allows you to extend unallocated space to any partition on the destination disk you want. 
  • Convert the destination disk from MBR to GPT: It helps to convert the partition style of the destination disk if it is different from the source disk. 

Add Unused Space
