Reasons to copy partition to another drive

Different from cloning an entire disk, copying a partition is a process of migrating only a selected partition (a part of the whole disk, not an entire disk) to another partition or other SSD/HDD. Generally, you can enjoy the following benefits from this operation.

• Back up important data: No matter if you plan to copy the system partition or data partition to SSD/HDD; you can make an exact backup of data stored on the selected partition.

• Get rid of bad sectors: If the disk, containing the selected partition, suffers some bad sectors, you can copy important partitions to another disk to avoid bad sectors.

• Transfer data quickly: When all crucial data is saved in one partition, or you just want to only keep this partition during disk replacement, copying a partition will help transfer data more quickly than copying a whole disk or copying files one by one.

If you are planning to delete partition, format partition, shrink partition, or extend partition, Windows built-in tools like Disk Management and Diskpart can help you a lot. But for cloning partition, you need to use a third-party utility since Windows doesn't offer such functions by far. AOMEI Partition Assistant Standard is a great tool to copy partition to another hard drive in Windows 11/10/8/7 and Windows XP/Vista all editions.

This free disk partition software provides you with two copy methods:
Clone Partition Quickly (file by file): only copies all existing files from the source partition to the destination disk.
Sector-by-Sector Clone (complete copy): copy both all available files and lost/deleted files from the source partition to the destination disk.

Besides using a professional partition clone tool to copy partition, you can also make use of the xcopy command to copy files and directories, including subdirectories from one partition to another. See how to use xcopy commands to clone a partition:

Step 1. Click “Start” and type “cmd”. Right-click on "cmd" and select “Run as administrator”.

Step 2. Type "xcopy c:\ f:\ /s /e /h /i /c /y" and press Enter to copy all the files and subdirectories (including any empty subdirectories, any system, or hidden files) from partition C to partition F. Replace the drive letter based on your situation.


The above parameters mean:
/s: copy directories and subdirectories except for empty ones. If you omit “/s”, xcopy will work within a single directory.
/e: copy all subdirectories, including the empty one.
/h: copy the hidden and system file.
/i: force xcopy to assume that destination is a directory
/c: force xcopy to continue even if it encounters an error.
/y: stop the xcopy command from prompting you about overwriting files from sources that already exist in the destination location.
