Prior Notice:

• The "Sector by sector copy" asks the size of your destination disk to be at least equal to or larger than that of the source disk. Leave this feature unchecked if you wish to clone a larger hard disk to a smaller hard disk.
• All data on the destination disk will be completely erased, so take care.

Step 1. To start copying/cloning an entire disk to another, choose this disk as the source disk under "Disk Mode" and click "Next".

Step 2. Choose the other disk as the destination disk.

Step 3. Check the disk layout of the two disks. You can manage the disk layout of the destination disk by selecting "Autofit the disk", "Copy as the source" or "Edit disk layout". 

• "Autofit the disk" makes some changes by default on the destination disk layout so that it can work at its best status.
• "Copy as the source"does not change anything on destination disk and the layout is the same as source disk.
• "Edit disk layout" allows you to manually resize/move partition layout on this destination disk.

Tick the "Check the option if the target is SSD" option to put your SSD in its best performance.

A message now appears, warning you that data will be lost. Please confirm this message by clicking "OK" and then click "Next".

Step 4. Click "Proceed" to officially execute the task.
