Get HDD (and NOT Volume) Serial Number on Vista Ultimate 64 bit

Question

I was once looking for getting the HDD serial number without using WMI, and I found it. The code I found and posted on StackOverFlow.com works very well on 32 bit Windows, b

Answer 1

use DeviceIoControl with IOCTL_STORAGE_GET_MEDIA_SERIAL_NUMBER

or check IOCTL_CHANGER_GET_PRODUCT_DATA

Answer 2

This code should give you the hard disk serial number. It's similar (ReadPhysicalDriveInNTWithAdminRights) to your code you linked to but with several additional functions.

Answer 3

This code makes three attempts at obtaining the serial number:

1. Using IOCTL_STORAGE_QUERY_PROPERTY.
2. Using SMART_RCV_DRIVE_DATA.
3. Using IOCTL_SCSI_PASS_THROUGH.

This code works for me on 64-bit:

And here's the code to call it:

' MainModule.vb

Module MainModule

    Sub Main()
        Console.WriteLine("{0}-bit runtime.", IntPtr.Size * 8)
        For drive As Integer = 0 To 4
            Try
                Console.WriteLine("Drive {0}, SMART:             [{1}]", drive, PhysicalDrive.GetSerialNumberUsingSmart(drive))
                Console.WriteLine("Drive {0}, Storage Query:     [{1}]", drive, PhysicalDrive.GetSerialNumberUsingStorageQuery(drive))
                Console.WriteLine("Drive {0}, SCSI Pass Through: [{1}]", drive, PhysicalDrive.GetSerialNumberUsingScsiPassThrough(drive))
            Catch ex As Exception
                If ex.Data("Context") IsNot Nothing Then Console.Error.Write("{0} failed: ", ex.Data("Context"))
                Console.Error.WriteLine(ex.Message)
            End Try
        Next
    End Sub

End Module

EDIT - I've changed the main method to display the results of each attempt for comparison. This will hopefully illustrate how hit and miss these techniques can be.

Answer 4

Got working on Windows 7 64:

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

        foreach (ManagementObject obj in mos.Get()) {
            Trace.TraceInformation("Information about disk drive {0}:", obj["Name"]);
            Trace.Indent();
            foreach (PropertyData pd in obj.Properties)
                Trace.TraceInformation("Name \"{0}\": \"{1}\"", pd.Name, pd.Value);
            Trace.Unindent();

            obj.Properties["SerialNumber"]
        }

Probably the class Win32_PhysicalMedia is not served on 64 bit platforms.

Even Disk32, at this time, is working (apart a bug when flipping serial number bytes), because is based on the same concepts.

Answer 5

Modified from the code here:

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

namespace Console_DiskDrive
{
    class Program
    {
        static void Main(string[] args)
        {
            String query = "SELECT * FROM Win32_DiskDrive";

            foreach (ManagementObject item in new ManagementObjectSearcher(query).Get())
            {
                string serialNumber = Convert.ToString(item["SerialNumber"]);

                Console.WriteLine(serialNumber);
            }

            Console.ReadLine();
        }
    }
}

On my system running Vista Home Premium x64, gives me a 40-character hex string that I'm assuming is my serial number. I'll open up the box and confirm later, but give that a try and see if it's what you're looking for.

Answer 6

You need to ensure that your P/Invoke definitions are 64-bit friendly. Alternatively, try setting the target CPU of the projects in your solution to 32-bit. More information on P/Invoke and 64-bit can be found here.

EDIT:

The following rewritten code might work better for you - basically I've tidied up the P/Invoke definitions and added better error handling. The code makes two attempts to obtain the serial number. The first uses IOCTL_STORAGE_QUERY_PROPERTY and the second uses SMART_RCV_DRIVE_DATA.

This is the code to call it:

' MainModule.vb

Module MainModule

    Sub Main()
        Console.WriteLine("{0}-bit runtime.", IntPtr.Size * 8)
        For drive As Integer = 0 To 4
            Try
                Console.WriteLine("Drive {0} - serial number: [{1}]", drive, PhysicalDrive.GetSerialNumber(drive))
            Catch ex As Exception
                If ex.Data("Context") IsNot Nothing Then Console.Error.Write("{0} failed: ", ex.Data("Context"))
                Console.Error.WriteLine(ex.Message)
            End Try
        Next
    End Sub

End Module

I only have one 64-bit machine to test against, but this code does work on it.
