What does cloning a partition do?

Cloning partition can be also called copying partition, which is a process of copying whole partition data into another new partition or hard disk. After clone, the destination partition will be loaded with the same data as the source partition. In brief, cloning a partition can help a full and faithful copy of the source partition in Windows 11/10/8/7.

In this way, you can make a backup to quickly get back important data when your current hard drive fails. Besides, it is also a method of transferring a large amount of data more conveniently and safely. For example, when you want to move everything including installation packs from one partition to another hard disk volume, SSD, HDD or other hard drives, it’s better to clone partition than copying files one by one that may cause programs or OS boot failure.

Does Windows 10 have cloning software?

When it comes to cloning partition in Windows 10, most users would ask: "Does Windows 10 have cloning software to help copy some partition?".  Unluckily, for the task of copying all contents from one partition to another, the Windows 10 only offers a built-in option called System Image, which only allows you to create a complete replication of the OS drive and then restore it to another device. Briefly, the Windows 10 only offers the way to create a system drive image, not provide any cloning feature.

 From above, we know a professional partition cloning tool is necessary for flexibly cloning a partition in Windows 11, 10, 8, 7.

AOMEI Partition Assistant Standard provide two different methods to clone partition for different requirements:

Clone Partition Quickly: copy all existing files from one partition to another partition or hard disk. In this method, the total space of destination location should be large enough to hold all existing files on the original partition.
Sector-by-Sector Clone: copy all available sectors (including used sectors, blank sectors and bad sectors) from the source partition to destination space. It can ensure the destination partition is exactily same as the source partition.  This method requires that target disk space should surpass the total space of the partition being cloned.

If you will clone partition to another different hard disk, make sure the hard disk is connected to your Windows 10 computer and it is detected successfully. To connect the second hard disk, you may need a SATA to USB adapter cable.
