Every hard drive has a distinctive Volume Serial Number, with the chances of any two drives you encounter having the same serial number astronomically high. For this reason, the Volume Serial Number is often used as part of copy protection schemes. One caution is that operating system re-installations and upgrades may change a Volume Serial Number, and formatting certainly will.
