How to Copy&Clone Your Disk to New Hard Drive with Partition Assistant?

At some point, you intend to upgrade your computer hard drive or buy a new computer, and to transfer Operating System hard drive is especially a headache. On the other hand, if reinstall the OS on the new drive, you must reinstall all the software and set up your personal configurations once again. Applications installed on the old drive will fail to run on new one because of the lack of old Windows registry. In this case, the best way to solve the problem is to clone disk.

As an all-in-one partition manager, AOMEI Partition Assistant can help you make an identical copy of your hard drive, including the Operating System, applications, personal configurations and data.

What's more, this disk clone software can not only support copy disk quickly but also sector-by-sector copy. You can choose the appropriate method to clone disk based on your needs. Compared with the two methods, each has both advantages. Copy disk quickly method, also called file-by-file copy, can only clone the used space of the source disk to a new hard drive, but it is much faster than the other because it only clone files. However, sector-by-sector copy method allows you to clone all the sectors of the source disk to a target hard drive no matter whether it is used or not. What's better, the deleted, lost files or inaccessible data only can be cloned with sector-by-sector copy. Once the cloning operation is complete, you can recover the files from the target disk with data recovery software.


  • All data on target disk will be erased after you apply the operation.

  • System/Boot disk, dynamic disk, GPT disk and offline disk can't be selected as a target disk.

  • The target disk may be smaller than the source, but it should be equal or larger than the used space of the source disk.

  • It will offer an option to restart the computer when the source disk contains system partition.
