Every hard disk has a unique serial number which we can get by our code here is a example which gives you the you computer's c drive serial number.

using System.Management;

public string GetHDDSerialNumber(string drive)

        {

            //check to see if the user provided a drive letter

            //if not default it to "C"

            if (drive == "" || drive == null)

            {

                drive = "C";

            }

            //create our ManagementObject, passing it the drive letter to the

            //DevideID using WQL

            ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"" + drive + ":\"");

            //bind our management object

            disk.Get();
