Benefits of “copying (NTFS) partition”

To copy NTFS partition means copying all data from a NTFS partition to another disk. Compared with copying files one by one directly, cloning an entire partition can save much time. Briefly, to clone partitions always brings the following benefits.

> Backup data: no matter you plan to copy the system partition or data partition, you can finally backup any important data stored on it.

> Avoid bad sectors: if the disk has some bad sectors and needs to be exchanged, you can clone its important partition to another new disk.

> Save time and disk space: copying an entire disk will take a lot of precious time, so gathering all vital data into one partition and then copying the partition will help to save both time and space.

> Transfer data: if all your concerned files are stored in one partition or you just want to keep this partition when exchanging the disk, then you can make it easy via copying partition instead of the whole disk.

Can you copy partition via any Windows Built-in tools?

When the time comes to clone NTFS partition, you might think about Diskpart and Disk Management. Both of the Windows built-in tools indeed offer much help when managing the disks. For example, they can help you to delete partition, shrink partition, extend partition or format partition, etc. But is it able to copy NTFS partition, too? Well, sorry to say that you cannot copy partition via either of them no matter which operating system you are mainly using.
