How to get disk ID using C# (not “SerialNumber”)?

Question

I'd like to retrieve the Disk ID of my hard drive using C#.

I do not want "SerialNumber" as most articles talked since it's absent on my box.

To check this ID , you can run "cmd" on windows:

  diskpart
  list disk
  select disk 0
  detail disk

The output is like:

  HGST HTS725050A7E630
  Disk ID: 1033D54D
  ...

On my virtual box the output is

VBOX HARDDISK
Disk ID: 22452244

The disk ID seems to be a 32bit integer.

Is there anyway to get the same thing using C# (using API instead of parsing cmd output)?

Answer 1

This value is stored as the 'Signature'. You get this the same place that you get the Serial Number.

ManagementObjectSearcher win32DiskDrives = new ManagementObjectSearcher("select * from Win32_DiskDrive");
foreach (ManagementObject win32DiskDrive in win32DiskDrives.Get())
{
    Console.WriteLine("{0:X}", win32DiskDrive.Properties["Signature"].Value);
}

Answer 2

You could use WMI and the Win32_DiskDrive class. There are both a DeviceID and a SerialNumber properties, you might want to check if it contains the value you're looking for.
