Reasons to copy partition to another drive
Different from cloning an entire disk, copying partition is a process of migrating only a selected partition (a part of whole disk, not an entire disk) to another partition or other SSD/HDD. Generally, And you can enjoy the following benefits from this operation.
Back up important data: No matter you plan to copy 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 partition will help transfer data more quickly than copying a whole disk or copying files one by one.

Besides using a professional partition clone tool to copy partition, you can also make use of 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 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 source that already exist in the destination location.
