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 a HDD.

To Clone Disk:

  1. In the left tab page, select the Clone option and then select Disk Clone.
  2. Disk Clone

  3. Select the source disk that you want to clone. Click Next.
  4. Source Disk

  5. Select the destination disk to which the source disk will be cloned, and click Next.
  6. Destination Disk

    Warning! The destination disk and all existing data will be overwritten.

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


    a) If you want to adjust the partitions size or location on the destination disk, click the "Edit partitions on the destination disk" button. Options available are:

    1. Copy without resizing partitions: Do not do any changes.
    2. Fit partition to entire disk: The destination disk partitions will be automatically resized to the entire disk, appropriate for the disk size.
    3. Edit partitions on this disk: Manually adjust the partition size and location by dragging a slider bar.

    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.

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

  8. Finally, click Start Clone. Wait for the process to complete and then click Finish. A disk clone can take several hours depending on the size of the source disk.
  9. Start Disk

  • Note that the destination disk will be overwritten. Therefore if it contains any important data, you must backup the destination disk before you apply the operation.
  • If the destination disk is locked by other programs or applications running on it, AOMEI Backupper will ask to restart the computer, and will execute the disk clone operation in a "Restart Mode".
