Clone Hard Drive for Disk Upgrade, Data Transfer, SSD Migration

Updated on Apr 08, 2019 by Hana Lee to Todo Backup Guide

Disk clone can quickly transfer data, programs, system to the new hard drive. When we need to upgrade disk, migrate SSD, data transfer, cloning the entire disk would be a good choice.

Why Do We Clone Disk

We don't want to take much time or power to copy the folder one by one from one disk to another, or waste time to reinstall the operating system and software after a disk upgrade. You also may experience the below situations: don't know how to make a copy of the source disk as backup via sector level or file level, make a copy of damaged hard disk via sector level and recover lost data from the copied disk. If you have the above trouble or plan to migrate data, programs, system to the new hard drive, you need EaseUS Todo Backup to clone the disk.

How to Clone a Hard Drive or SSD

There are some tips we should notice during the disk cloning process:

  • Disk clone could clone one hard disk to another, and you could clone to a large or small disk, but, the size of the destination disk must large than the used space on the source disk.
  • Please shut down the computer after the clone if the source disk contains the system partition.
  • You don't have to remove either the source disk or destination disk from the computer, you just need to go to BIOS to change to start order to make the computer boot normally if the source disk contains boot partition.
  • If you want to boot from the destination disk, we recommend you to replace the source disk with the destination disk.

Step 1. Launch EaseUS Todo Backup and click "Clone". And it will pop up the below window and choose the source disk and destination disk.


Step 2. If you are using an SSD, you'd better select "Optimize for SSD". Normally, you don't need to select "Sector by sector clone", because it will clone all sectors from the source disk to the destination disk and take more time. We can preview the disk map in advance by clicking "Layout".


If the computer fails to boot from the destination disk after the clone, we suggest you clone the source disk to another disk with the same HDD interface. If you choose to clone a hidden partition, the cloned one will be un-hidden.
