Qiling Disk Copy is a straightforward tool that completes the disk cloning process with just a few clicks. Before cloning, connect the new M.2 SSD to your computer or laptop using a SATA to USB cable or an adaptor, ensuring it is recognized by the system.

Prior Notice:

  • The destination disk will be completely erased, so take care.

Step 1. To start copying or cloning an entire disk to another, select the disk you want to copy as the source disk under "Disk Mode" and click "Next".
