Disk Clone

September 10, 2019

Disk clone can clone a hard disk from one to another, and all the data and files on the disk will be transferred, including the operating system, applications, configuration settings and so on.

What Is Disk Clone?

Disk clone faithfully copies a hard disk drive from one to another. All data on the disk including operating system, applications, configuration settings and all partitions etc. will be transferred to the destination. This feature is especially useful when your system disk starts to run out of space, enabling you to upgrade your disk to one with higher capacity. You can also use Disk Clone to migrate from HDD to SSD, or for making a duplicate of an HDD.

How to Use AOMEI Backupper Clone?

AOMEI Backupper is a third party software which aims at system, partition/volume, disk as well as file/folder backup and restore. Also, it supports clone function, 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 do disk clone for free.

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

To Clone Disk:

1. In the left tab page, select the Clone option 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, and click Next.

    Select Destination Disk

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

Advanced Options

a) To adjust the size or location of the partition on the destination disk, select the "Edit partitions" button. The following options are available:

  • Copy without resizing partitions: Does not do any changes.

  • 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 system is bootable after cloning.

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

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

  • 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 on the destination disk” option is unavailable.

  • To ensure destination disk accessible after cloning, you should connect target disk as internal before clone. And, if source disk and target disk are in different type (one is MBR and the other is GPT), you have to modify the boot mode in BIOS when you boot from the target drive.

  • For encrypted disk, Backupper will use sector by sector clone way 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 way to clone these partitions.

  • Disk clone doesn’t support dynamic disk. Please useSystem Clone or Partition Clone way.
