general info
 

Hard disk cloning, like drive cloning, is creating a full copy of the drive or partition on it.
3rd party software will be needed and the disk(or partition) can only be copied onto a device with same or more space available.
If the configuration of the PC that will be using the drive later is the same(or very similar) to the the one that used the original, you have a pretty good chance that no tweaks or changes will need to be done whatsoever for it to work later on.
