What is Disk Clone?

Disk Clone (also called Disk Copy) is the process of creating a 1-to-1 copy of an HDD or SSD, not just its files but its operating system, partition layout, drive letter, customized settings, installed programs, personal data, etc. All contents on the original disk can be transferred to the destination disk, which enables you to boot to the operation system from the cloned drive.

Why Need Disk to Disk Cloning?

Disk cloning is very useful in many scenarios, and here are 3 common scenarios.

In order to improve computer performance, it is a common practice to make a hard disk drive replacement or upgrade.
◑ Make a duplicate of your HDD/SSD as a backup. Sometimes, we backup folders to USB drive or other external drives in order to protect our precious data. However, this cannot keep all data and information when some unexpected disasters occur, disk to disk copy will prevent you from losing valuable data or reinstalling the system and configuration settings. You can get full data recovery in the event of a machine crash.
◑ Migrate some data to another place. In our daily life, we have some special documents or data, we don’t want to put them with others together. For the sake of ensuring the security of these data, we choose to clone them to another disk. And we can transfer them to any devices if we want to.
