Will the hard disk copy copy data into the system?

If you mean moving the operating system from the old hard disk to the new hard disk, you can use Ghost tool software to clone the data of the whole disk to the new disk, that is, copy the data of the old disk to the new disk intact. Usually, you need to make a U disk tool for PE system first, then use it to start the system, and then use the Ghost software attached to it to move data. If you reinstall the operating system on the new hard disk, after the installation is completed, hang up the old hard disk and use ordinary file copy operation to move the data of the old disk to the new disk. You can also install an old disk in the host and use its saved data directly.
