I think GetVolumeInformation (http://msdn2.microsoft.com/en-us/library/aa364993.aspx) might be what you're after.

Parameter four, lpVolumeSerialNumber , specifically.

Try this

C++:
DWORD V, M, F;
GetVolumeInformation("C:\", NULL, 0, @V, M, F, NULL, 0);

// V has the Serial Number of GetVolumeInformation of the C drive.

Customize it, add math.

Code:
Option Explicit
Private Declare Function GetVolumeInformation Lib "kernel32" Alias "GetVolumeInformationA" (ByVal RootPathName As String, ByVal VolumeNameBuffer As String, ByVal VolumeNameSize As Long, ByRef VolumeSerialNumber As Long, ByRef MaximumComponentLength As Long, ByRef FileSystemFlags As Long, ByVal FileSystemNameBuffer As String, ByVal FileSystemNameSize As Long) As Long

Private Sub Form_Load()
Dim VolumeName As String, SerialNumber As Long, Unused As Long
VolumeName = String$(64, 0)

If GetVolumeInformation("C:\", VolumeName, Len(VolumeName), _
        SerialNumber, Unused, Unused, vbNullString, 0) <> 0 Then
    Debug.Print "Volume label:  "; Trim(VolumeName)
    Debug.Print "Serial number: "; Hex$(SerialNumber)
Else
    Debug.Print "Error: " & Err.LastDllError
End If
End Sub
