Follow the steps below to clone your old hard drive to a new drive. Once the drive has been cloned, just simply remove the existing drive and replace it with the new one. The whole procedure of clone will be quite easy even if you’re not a computer expert. Let’s start.

Step 2. Click Clone on the main interface and then select Disk Clone.

Step 3. Select your existing drive as the source disk.

Step 4. Select the destination disk. You are allowed to replace larger hard drive with smaller SSD as long as the used space is smaller than the target drive.

Tip: A window will pop up to inform you that data on the destination disk will be overwritten. So if you have important documents there, please back them up first. Click “OK” to continue.

Step 5. Now comes the operation summary. Confirm the operation and click Start Clone. Before starting clone, there are three more options in the bottom.

• Edit Partitions: it enables you to adjust partition size on the destination disk, which can help to solve unallocated space left after cloning.

• Sector by sector clone: it will copy all sectors no matter they’re used or not. If you are going to clone your hard drive to a smaller disk, do not tick this option.

• SSD Alignment: if the destination disk is an SSD, use this option to improve its reading and writing speed.

Note: This operation will not cause data loss. However, data loss can be caused by other unexpected factors such as inappropriate operations and battery failure. Therefore, backup data before replacing hard drive just in case.

The final step to replace your hard drive without losing data is to swap drives. When doing this, make sure that you understand any information regarding your warranty. Any unauthorized work on your system may void the warranty of system manufacturers. Plus, review the safety instructions inside your system product manuals before working.

✍ Note for secure boot: 

If you've cloned the disk with operating system installed, you can boot up Windows from the cloned drive by changing boot priority in BIOS or switching boot drives directly.
