Find Serial no of hard disk using C#

Hi,

be careful here, there are several traps.

1.
each partition has a serial number, that one is easy to get. It gets assigned when the partition gets formatted, hence it can change over time.

Most Google hits tend to point to the partition's serial number (as that is the easiest to get), without always making that clear.

2.
each physcial disk has a data structure, with one field holding the physical serial number. It requires the vendor's collaboration, which normally isn't a problem. AFAIK the number cannot change over time (unless you replace the device of course).

There are several ways to get it (using WMI, using device-level file operations), however each of those would require elevation on Vista and later systems.

:)

You can download WMI explorer (http://www.ks-soft.net/hostmon.eng/wmi/index.htm[^]) and find the serial number by yourself.
Hope this will help.
Best wishes!

Hi Dmitry Vitkovsky

I downloaded the file you asked to download but it is also not showing the result which I expected Is there any other way or which can solve my problem. Any way thanks for the reply...

This is my code which is I using to display serial number. It displays all other properties axcept serialnumber.

ManagementObjectSearcher searcher = new ManagementObjectSearcher();
            searcher.Query = new ObjectQuery("select * from Win32_PhysicalMedia ");
            foreach (ManagementObject obj in searcher.Get())
            {
                Console.WriteLine(obj["SerialNumber"]);
            }

What is the possible way to identify a system uniquely?
