Get Hard disk serial Number

Question

I want to get hard disk serial number. How I can I do that? I tried with two code but I am not getting

StringCollection propNames = new StringCollection();
ManagementClass driveClass = new ManagementClass("Win32_DiskDrive");
PropertyDataCollection  props = driveClass.Properties;
foreach (PropertyData driveProperty in props) 
{
    propNames.Add(driveProperty.Name);
}
int idx = 0;
ManagementObjectCollection drives = driveClass.GetInstances();
foreach (ManagementObject drv in drives)
       {
          Label2.Text+=(idx + 1);
          foreach (string strProp in propNames)
           {
            //Label2.Text+=drv[strProp];
         Response.Write(strProp + "   =   " + drv[strProp] + "</br>");
          }
    }

In this one I am not getting any Unique Serial number.
And Second one is

string drive = "C";
ManagementObject disk = new ManagementObject("win32_logicaldisk.deviceid=\"" + drive + ":\"");
disk.Get();
Label3.Text = "VolumeSerialNumber="+ disk["VolumeSerialNumber"].ToString();

Here I am getting VolumeSerialNumber. But it is not unique one. If I format the hard disk, this will change. How Can I get this?

Solution 1

Hm, looking at your first set of code, I think you have retrieved (maybe?) the hard drive model. The serial # comes from Win32_PhysicalMedia.

Get Hard Drive model

    ManagementObjectSearcher searcher = new
    ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

   foreach(ManagementObject wmi_HD in searcher.Get())
   {
    HardDrive hd = new HardDrive();
    hd.Model = wmi_HD["Model"].ToString();
    hd.Type  = wmi_HD["InterfaceType"].ToString(); 
    hdCollection.Add(hd);
   }

Get the Serial Number

 searcher = new
    ManagementObjectSearcher("SELECT * FROM Win32_PhysicalMedia");

   int i = 0;
   foreach(ManagementObject wmi_HD in searcher.Get())
   {
    // get the hard drive from collection
    // using index
    HardDrive hd = (HardDrive)hdCollection[i];

    // get the hardware serial no.
    if (wmi_HD["SerialNumber"] == null)
     hd.SerialNo = "None";
    else
     hd.SerialNo = wmi_HD["SerialNumber"].ToString();

    ++i;
   }

Hope this helps :)

Solution 2

I have used the following method in a project and it's working successfully.

private string identifier(string wmiClass, string wmiProperty)
//Return a hardware identifier
{
    string result = "";
    System.Management.ManagementClass mc = new System.Management.ManagementClass(wmiClass);
    System.Management.ManagementObjectCollection moc = mc.GetInstances();
    foreach (System.Management.ManagementObject mo in moc)
    {
        //Only get the first one
        if (result == "")
        {
            try
            {
                result = mo[wmiProperty].ToString();
                break;
            }
            catch
            {
            }
        }
    }
    return result;
}

you can call the above method as mentioned below,

string modelNo = identifier("Win32_DiskDrive", "Model");
string manufatureID = identifier("Win32_DiskDrive", "Manufacturer");
string signature = identifier("Win32_DiskDrive", "Signature");
string totalHeads = identifier("Win32_DiskDrive", "TotalHeads");

If you need a unique identifier, use a combination of these IDs.

There is a simple way for @Sprunth's answer.

private void GetAllDiskDrives()
    {
        var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");

        foreach (ManagementObject wmi_HD in searcher.Get())
        {
            HardDrive hd = new HardDrive();
            hd.Model = wmi_HD["Model"].ToString();
            hd.InterfaceType = wmi_HD["InterfaceType"].ToString();
            hd.Caption = wmi_HD["Caption"].ToString();

            hd.SerialNo =wmi_HD.GetPropertyValue("SerialNumber").ToString();//get the serailNumber of diskdrive

            hdCollection.Add(hd);
        }

 }


public class HardDrive
{
    public string Model { get; set; }
    public string InterfaceType { get; set; }
    public string Caption { get; set; }
    public string SerialNo { get; set; }
}

Use "vol" shell command and parse serial from it's output, like this. Works at least in Win7

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace CheckHD
{
        class HDSerial
        {
            const string MY_SERIAL = "F845-BB23";
            public static bool CheckSerial()
            {
                string res = ExecuteCommandSync("vol");
                const string search = "Number is";
                int startI = res.IndexOf(search, StringComparison.InvariantCultureIgnoreCase);

                if (startI > 0)
                {
                    string currentDiskID = res.Substring(startI + search.Length).Trim();
                    if (currentDiskID.Equals(MY_SERIAL))
                        return true;
                }
                return false;
            }

            public static string ExecuteCommandSync(object command)
            {
                try
                {
                    // create the ProcessStartInfo using "cmd" as the program to be run,
                    // and "/c " as the parameters.
                    // Incidentally, /c tells cmd that we want it to execute the command that follows,
                    // and then exit.
                    System.Diagnostics.ProcessStartInfo procStartInfo =
                        new System.Diagnostics.ProcessStartInfo("cmd", "/c " + command);

                    // The following commands are needed to redirect the standard output.
                    // This means that it will be redirected to the Process.StandardOutput StreamReader.
                    procStartInfo.RedirectStandardOutput = true;
                    procStartInfo.UseShellExecute = false;
                    // Do not create the black window.
                    procStartInfo.CreateNoWindow = true;
                    // Now we create a process, assign its ProcessStartInfo and start it
                    System.Diagnostics.Process proc = new System.Diagnostics.Process();
                    proc.StartInfo = procStartInfo;
                    proc.Start();
                    // Get the output into a string
                    string result = proc.StandardOutput.ReadToEnd();
                    // Display the command output.
                    return result;
                }
                catch (Exception)
                {
                    // Log the exception
                    return null;
                }
            }
        }
    }

Here is a solution using win32 api and std string in case you need your application to run on a OS with no CLR. I found it here on github.

#include "stdafx.h"
#include <windows.h>
#include <memory>
#include <string>

//returns the serial number of the first physical drive in a std::string or an empty std::string in case of failure
//based on http://codexpert.ro/blog/2013/10/26/get-physical-drive-serial-number-part-1/
std::string getFirstHddSerialNumber() {
    //get a handle to the first physical drive
    HANDLE h = CreateFileW(L"\\\\.\\PhysicalDrive0", 0, FILE_SHARE_READ | FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL);
    if (h == INVALID_HANDLE_VALUE) return{};
    //an std::unique_ptr is used to perform cleanup automatically when returning (i.e. to avoid code duplication)
    std::unique_ptr<std::remove_pointer<HANDLE>::type, void(*)(HANDLE)> hDevice{ h, [](HANDLE handle){CloseHandle(handle); } };
    //initialize a STORAGE_PROPERTY_QUERY data structure (to be used as input to DeviceIoControl)
    STORAGE_PROPERTY_QUERY storagePropertyQuery{};
    storagePropertyQuery.PropertyId = StorageDeviceProperty;
    storagePropertyQuery.QueryType = PropertyStandardQuery;
    //initialize a STORAGE_DESCRIPTOR_HEADER data structure (to be used as output from DeviceIoControl)
    STORAGE_DESCRIPTOR_HEADER storageDescriptorHeader{};
    //the next call to DeviceIoControl retrieves necessary size (in order to allocate a suitable buffer)
    //call DeviceIoControl and return an empty std::string on failure
    DWORD dwBytesReturned = 0;
    if (!DeviceIoControl(hDevice.get(), IOCTL_STORAGE_QUERY_PROPERTY, &storagePropertyQuery, sizeof(STORAGE_PROPERTY_QUERY),
        &storageDescriptorHeader, sizeof(STORAGE_DESCRIPTOR_HEADER), &dwBytesReturned, NULL))
        return{};
    //allocate a suitable buffer
    const DWORD dwOutBufferSize = storageDescriptorHeader.Size;
    std::unique_ptr<BYTE[]> pOutBuffer{ new BYTE[dwOutBufferSize]{} };
    //call DeviceIoControl with the allocated buffer
    if (!DeviceIoControl(hDevice.get(), IOCTL_STORAGE_QUERY_PROPERTY, &storagePropertyQuery, sizeof(STORAGE_PROPERTY_QUERY),
        pOutBuffer.get(), dwOutBufferSize, &dwBytesReturned, NULL))
        return{};
    //read and return the serial number out of the output buffer
    STORAGE_DEVICE_DESCRIPTOR* pDeviceDescriptor = reinterpret_cast<STORAGE_DEVICE_DESCRIPTOR*>(pOutBuffer.get());
    const DWORD dwSerialNumberOffset = pDeviceDescriptor->SerialNumberOffset;
    if (dwSerialNumberOffset == 0) return{};
    const char* serialNumber = reinterpret_cast<const char*>(pOutBuffer.get() + dwSerialNumberOffset);
    return serialNumber;
}

#include <iostream>
int main() {
    std::string serialNumber = getFirstHddSerialNumber();
    if (serialNumber.empty())
        std::cout << "failed to retrieve serial number\n";
    else
        std::cout << "serial number: " << serialNumber << "\n";
    return 0;
}
