Edit Partitions: It allows you to edit partition size on target disk as you wish. Also, it supports converting the disk partition style. Checking “Sector by sector clone” option will make this option unavailable.

  • 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 as you want. 
  • Convert the destination disk from MBR (GPT) to GPT (MBR): It helps to convert the partition style of the destination disk if it is different from that of the source disk.

Edit Partitions

✍ If a GPT disk has more than 4 primary partitions and you want to copy from GPT to MBR disk, make sure you check "Convert the destination disk from MBR to GPT". Otherwise, AOMEI Backupper will only copy up to 3 partitions due to partition style limitations.

Sector by sector clone: by checking this option, AOMEI Backupper will copy every sector from the source to the target, whether it is used or not. It requires the target disk to be equal to or larger than the source disk.

✍AOMEI Backupper is also operating system cloning software which allows you to copy only OS to Samsung SSD.


You may be strange why you cannot let Samsung Data Migration change source disk while cloning. The truth is it will run only if the operating system is installed on the Source Disk. So you can use it to move operating system to Samsung SSD only.

However, if you’d like to copy a disk where no operating system is installed or image a data drive to Samsung SSD, it is suggested to turn to another disk cloning software like AOMEI Backupper.
