Partition/Disk Clone Wizards in AOMEI Partition Assistant

March 28, 2022

What’s the best way for disk clone and partition clone? Here, you’ll not only why you need to clone them but also, learn how to carry out the partition/disk clone with the help of a powerful third-party disk manager.

Why do you need to clone a hard disk?

By cloning/ copying a hard disk, you can make a duplicate of your current hard disk. It’s a nice choice to duplicate your hard drive under the two following conditions:

  • Upgrade to SSD or larger disk without apps and OS reinstallation: If you want to replace your old hard disk with SSD or a larger disk while keeping all apps & current OS, you can copy disk to transfer all data, including OS to another one.

  • Back up your system and data for safety: Through disk copy, you can get an exact backup of what is stored on your hard disk in use. Thus you can quickly replace the original hard drive with the cloned one if the current disk is failing.

Without knowing anything of the disk clone, I did suffer the tedious and tiresome work before. That happened when I just entered college and had my own PC. In order to avoid data loss due to my improper operation since I was not familiar with using a computer then, I decided to back up all the things the D drive to my USB flash drive. Then, I copied the files and folders one by one. The result turned out literally frustrating – some boot files of apps are lost during the copy-paste process and I can no longer boot those apps.

Why do you need to clone a partition?

Partition Clone can help you quickly back up your important partition or migrate partition from one hard disk to another hard disk so as to prevent data loss caused by program error or some other accidental affairs. This function can be useful, either as a means of making a backup or for the distribution of an identical environment to multiple computers.

Preparations before disk clone

There’re some important things you should do before the disk clone begins.
