Get Serial Number of Boot Drive and other info

I am trying to get the serial number of the boot drive and I haven't figured out how to do it.

I do understand that the partition =\= hard drive but I'd like the serial of the boot partition.

This what I have so far:

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

        int i = 0;
        foreach (ManagementObject wmi_HD in searcher.Get())
        {
            // get the hardware serial no.
            if (wmi_HD["SerialNumber"] == null)
                richTextBox1.Text += "None" + Environment.NewLine;
            else
                richTextBox1.Text += "Name: " + wmi_HD["Name"] + Environment.NewLine;
                richTextBox1.Text += "SerialNumber: " + wmi_HD["SerialNumber"] + Environment.NewLine;
                richTextBox1.Text += "MediaType: " + wmi_HD["MediaType"] + Environment.NewLine;
                richTextBox1.Text += "Removable: " + wmi_HD["Removable"] + Environment.NewLine;

            ++i;
        }

I have looked here:

http://msdn.microsoft.com/en-us/library/windows/desktop/aa394346(v=vs.85).aspx#properties

To see if I could see if it was the boot drive and I don't see anything.

I'm getting nothing returned on anything but the SerialNumber, everything else is blank.

This is what I get on the above code:

Name:

SerialNumber: 5YZ01J34

MediaType:

Removable:

How do I get the serial number of the boot drive and also the information that is not showing above?

Thanks again!

Here you're talking about a drive (as it's bootable), not a disk. A drive is logical and represented by a letter (C, D....etc.), and a disk is physical and represented by a number (from 0 to N). In your example you used WMI and Win32_PhysicalMedia, which is wrong as this class is about disks, not drives.

Here is what you want using P/Invoke:

namespace ConsoleApplication3
{
    using System.Runtime.InteropServices;
    using System.Text;

    public class Drive
    {
        [DllImport("kernel32.dll", CharSet = CharSet.Auto, SetLastError = true)]
        private static extern bool GetVolumeInformation(
            string rootPathName,
            StringBuilder volumeNameBuffer,
            int volumeNameSize,
            ref uint volumeSerialNumber,
            ref uint maximumComponentLength,
            ref uint fileSystemFlags,
            StringBuilder fileSystemNameBuffer,
            int nFileSystemNameSize);

        public string VolumeName { get; private set; }

        public string FileSystemName { get; private set; }

        public uint SerialNumber { get; private set; }

        public string DriveLetter { get; private set; }

        public static Drive GetDrive(string driveLetter)
        {
            const int VolumeNameSize = 255;
            const int FileSystemNameBufferSize = 255;
            StringBuilder volumeNameBuffer = new StringBuilder(VolumeNameSize);
            uint volumeSerialNumber = 0;
            uint maximumComponentLength = 0;
            uint fileSystemFeatures = 0;
            StringBuilder fileSystemNameBuffer = new StringBuilder(FileSystemNameBufferSize);

            if (GetVolumeInformation(
                string.Format("{0}:\\", driveLetter),
                volumeNameBuffer,
                VolumeNameSize,
                ref volumeSerialNumber,
                ref maximumComponentLength,
                ref fileSystemFeatures,
                fileSystemNameBuffer,
                FileSystemNameBufferSize))
            {
                return new Drive
                    {
                        DriveLetter = driveLetter,
                        FileSystemName = fileSystemNameBuffer.ToString(),
                        VolumeName = volumeNameBuffer.ToString(),
                        SerialNumber = volumeSerialNumber
                    };
            }

            // Something failed, returns null
            return null;
        }
    }
}


Drive drive = Drive.GetDrive("C");

Console.WriteLine(string.Format("Volumne name: {0}", drive.VolumeName));
Console.WriteLine(string.Format("File system name: {0}", drive.FileSystemName));
Console.WriteLine(string.Format("SerialNumber: {0:X}", drive.SerialNumber));

If you want more information about your drive, you can use DeviceIoControl with IOCTL_DISK_GET_DRIVE_GEOMETRY control code to get the geometry of the associated disk (bytes per cluster, sectors per track...).
You can also get additional information (starting offset, partition number, hidden sectors...) using IOCTL_DISK_GET_PARTITION_INFO control code.

Now, the same using WMI:

var searcher = new ManagementObjectSearcher("SELECT * FROM Win32_LogicalDisk");

foreach (ManagementObject drive in searcher.Get())
{
    Console.WriteLine("-------");
    Console.WriteLine(string.Format("VolumeName: {0}", drive["VolumeName"]));
    Console.WriteLine(string.Format("VolumeSerialNumber: {0}", drive["VolumeSerialNumber"]));
    Console.WriteLine(string.Format("MediaType: {0}", drive["MediaType"]));
    Console.WriteLine(string.Format("FileSystem: {0}", drive["FileSystem"]));
}

Note I've used Win32_LogicalDisk as we're talking about drives (named here logical disks).
