So many question about how to get hard disk physical serial number, and mostly answered by using WMI. And it doesn't solve my problem.

I used to use HDSN code that I got from Planet Source Code when I was still using Visual Basic 6 (VB6). And now with VB.NET I need the same result but I couldn't get it with WMI. Is there any other way to get  Factory Serial Number without WMI?

Finally I got the best solution using DeviceIOControl that I got from a blog named jo0ls' .Net stuff.
And I adapt it to my code to fulfill my need.

 

Here are the steps. First I created a windows form project/solution named HDDSerial Number, add a module name SerialNumber.vb and type below codes:
 

 

Imports System.Runtime.InteropServices

ImportsMicrosoft.Win32.SafeHandles

Imports System.Security

ImportsSystem.ComponentModel

Imports System.Text

Module SerialNumber

  <SuppressUnmanagedCodeSecurity()> _
  Private Class NativeMethods

      End Function

      <DllImport("kernel32.dll", SetLastError:=True)> _
      Friend Shared Function DeviceIoControl( _
          ByVal deviceHandle As SafeFileHandle, _
          ByVal controlCode As Integer, _

       FileShareRead Or FileShareWrite, _
       IntPtr.Zero, _
       OpenExisting, _
       0, _
       IntPtr.Zero)
          If driveHandle.IsInvalid Then
             Return "CreateFile ERROR: " & (New Win32Exception).Message
          End If
          Dim apex As New ATA_PASS_THROUGH_EX
          apex.Length = Marshal.SizeOf(apex)

          ' ATA_FLAGS_DATA_IN
          apex.AtaFlags = 2

          ' The command returns a 512 byte package of info.

          ' This contains the command we are requesting.
          apex.CurrentTaskFile = New Byte(7) {}
          'the command "IDENTIFY DEVICE"
          apex.CurrentTaskFile(6) = &HEC
          Dim apexb As New ATA_PASS_THROUGH_EX_WITH_BUFFERS
          apexb.Apt = apex
          Dim inBufferSize As Integer = Marshal.SizeOf( _
                   GetType(ATA_PASS_THROUGH_EX_WITH_BUFFERS))

          Select Case InfoType

                  Return GetString(apexb.Data, 20, 20)

          End Select
      End Using
  End Function

  Private Function GetString(ByVal bytes() As Byte, _
                             ByVal offset As Integer, _
                             ByVal length As Integer) As String
      ' The strings are slightly weird - endianness? 
      ' If you use ASCII.GetBytes Then Each character 
      ' pair is reversed.
      Dim sb As New StringBuilder()
      For i As Integer = offset To offset + length - 1 Step 2
          sb.Append(Chr(bytes(i + 1)))
          sb.Append(Chr(bytes(i)))
      Next
      Return RTrim(LTrim(sb.ToString))
  End Function

End Module

Set UI of Form1 Text "Hardisk Serial Number", add 3 labels and 3 TextBoxes. Name textboxes as txtSerialNumber, txtModel, and txtFirmware. 

Then type below code:
Imports System.Management

Public Class Form1
    Private Sub Form1_Load(ByVal sender As Object, _
          ByVal e As EventArgs) Handles MyBase.Load

        Try

            txtSerialNumber.Text = HDDInfo(HDINFO.HD_SERIAL_NUMBER)
            txtModel.Text = HDDInfo(HDINFO.HD_MODEL_NUMBER)
            txtFirmware.Text = HDDInfo(HDINFO.HD_FIRMWARE_REVISION)

        Catch ex As Exception
            MsgBox(ex.Message)
        End Try

    End Sub
End Class
Test run, then here is my PC result: 

 

Notes: Don't forget to Run as Administrator so application could work properly on Vista, Windows 7, and Windows 8.
