Note: Do remember to connect your good new hard drive to the computer as a storage device before upgrading the disk with bad sectors to the good one.

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".
