Diskpart UniqueID - C# how to get that id

Question

I'm familiar with VolumeSerialNumber, i need the Disk ID same as shown in diskpart:

WD My Passport 0740 USB Device Disk ID: 08B29B51 Type : USB Status : Online Path : 0 Target : 0 LUN ID : 0 Location Path : UNAVAILABLE Current Read-only State : No Read-only : No Boot Disk : No Pagefile Disk : No Hibernation File Disk : No Crashdump Disk : No Clustered Disk : No

I can't find anything on the web (WMI) or forums that supports this request. Anybody has an idea?

This is the Method i created for getting DiskID from Driveletter. Probably are better ways to do this, but this worked for me for now. Thanks for all your help.

    public static string GetDiskID(char Drive)
    {
        uint volumeSerialNumber = 0;
        bool DriveFound = false;
        foreach (ManagementObject drive in new ManagementObjectSearcher("select DeviceID, Signature from Win32_DiskDrive").Get())
        {
            foreach (ManagementObject partition in new ManagementObjectSearcher(String.Format("associators of {{Win32_DiskDrive.DeviceID='{0}'}} where AssocClass = Win32_DiskDriveToDiskPartition", drive["DeviceID"])).Get())
            {
                if (partition != null)
                {
                    ManagementObject logical = new ManagementObjectSearcher(String.Format("associators of {{Win32_DiskPartition.DeviceID='{0}'}} where AssocClass = Win32_LogicalDiskToPartition", partition["DeviceID"])).First();
                    if (logical != null)
                    {
                        if (logical["Name"] != null)
                        {
                            string logicalName = logical["Name"].ToString();
                            if (logicalName[0] == Drive)
                            {
                                volumeSerialNumber = (uint)drive["Signature"];
                                DriveFound = true;
                                break;
                            }
                        }
                    }
                }
            }
            if (DriveFound)
                break;
        }
         var serial = volumeSerialNumber.ToString("x");
            while (serial.Length < 8)
            {
                serial = serial.Insert(0, "0");
            }
            return serial.ToUpper();
   }

Check out the Win32_DiskDrive WMI Class. It has a field called Signature which contains this ID. Note, though, that this is not a string, but a number. If you want to match what you see in DiskPart, you'll have to display that number as a hexadecimal string (signature.ToString("X"))

Here's code to print out drive signatures:

public void PrintDiskDriveSignature()
{
    var searcher = new ManagementObjectSearcher
              (@"\\localhost\ROOT\CIMv2", "select * from Win32_DiskDrive");
    var drives = searcher.Get();
    foreach (var drive in drives)
    {
        string name = drive["Name"].ToString();
        uint signature = (uint) drive["Signature"];
        Console.WriteLine("{0}: {1}", name, signature.ToString("X"));
    }
}
