Disk Clone

November 5, 2019

Disk Clone is able to clone one hard disk to another. All of the data and files on the original disk will be transferred, this includes the operating system, applications, and configurations/settings.

What Is Disk Clone?

Disk Clone accurately copies one hard drive to another. All of the data and files on the original disk will be transferred, this includes the operating system, applications, partitions, and configurations/settings.

The Disk Clone function is particularly useful when your system disk starts to run out of space, thereby enabling you to upgrade your drive to a new one with a higher capacity. You can also use Disk Clone to migrate from your old HDD to a new SSD, or to make a duplicate of your original HDD.

How do you use AOMEI Backupper’s Disk Clone feature?

AOMEI Backupper is a third party software utility which supports system, partition/volume, disk as well as file/folder backup and restore. In addition, it supports cloning functions, such as disk clone, system clone, and partition/volume clone. Finally, there is a free version of AOMEI Backupper - AOMEI Backupper Standard Edition which contains most features and can perform disk cloning for free.

Here, we will use AOMEI Backupper Standard Edition as an example to show you how to use AOMEI Backupper for Windows disk clone. Before the start, download, install and open AOMEI Backupper.

How To Clone A disk:

1. Select ‘Clone’ from the left hand side menu and then select ‘Disk Clone’.

2. Select the source disk that you want to clone. Click ‘Next’.

    Select Source Disk

3. Select the destination disk to which the source disk will be cloned to, and click Next.

    Select Destination Disk

4. Preview the information showing your source and destination disk. In the wizard page, set desired advanced settings as follows:

Advanced Options

a) To adjust the size or the location of the partition on the destination disk, select the ‘Edit Partitions’ option. The following options are available:

  • Copy without resizing partitions: Does not make any changes to the partition sizes.

  • Add unused space to all partitions: The destination disk partitions will be automatically resized to the entire disk, appropriate for the disk size.

  • Manually adjust partition size: Manually adjust the partition size and location by dragging a slider bar. (available in AOMEI Backupper Pro)

Edit Partitions

b) Sector by sector clone: Copies all sectors of the disk to the destination disk whether in use or not. The destination disk size must be equal to or larger than the source disk. Usually, to save destination disk space, there is no need to tick this option. Unchecking AOMEI Sector by sector clone will only clone the used part of the source disk, thus the room required on the destination is smaller. Yet, the data or system is also intact unchecking Sector by sector clone and the system is still bootable after cloning.

c) SSD Alignment: If your destination disk is an SSD (Solid-State Drive), we highly recommend you check this option for optimizing the performance of the SSD.

5. Finally, click ‘Start Clone’. Wait for the process to complete and then click ‘Finish’.

Tips:

  • If the destination disk is locked by other programs and/or applications, then Backupper will request the computer is restarted to execute the disk clone operation in "Restart Mode".

  • If “Sector by sector clone” is selected, “Edit Partitions” option is unavailable.

  • To ensure the destination disk is accessible after cloning, you should install the target disk internally after cloning. Note if source disk and target disk are of different type (one uses MBR mode and the other uses GPT mode), you have to modify the boot mode in BIOS/UEFI when you boot from the target drive.

  • For encrypted disk, Backupper will use sector by sector clone mode by default.

  • The time to complete a disk clone task depends on the size of the source disk. Besides, the following aspects can also influence the operation speed:

    If there are non-NTFS or FAT32 partitions on the disk, Backupper will use sector by sector mode to clone these partitions.

  • Disk clone doesn’t support dynamic disks. Please use System Clone or Partition Clone options instead.

  • This version only supports cloning disk with the same partition tyle, such as, cloning GPT disk to GPT disk. If you want to clone GPT disk to MBR or migrate MBR disk to GPT, you could consider upgrading to AOMEI Backupper Professional.
