.NET still does not expose the drive serial number via the framework. For that you will need to use WMI. Here is the code.
Shared Function GetDriveSerialNumber(ByVal drive As String) As String
Dim driveSerial As String = String.Empty
'No matter what is sent in, get just the drive letter
Dim driveFixed As String = System.IO.Path.GetPathRoot(drive)
driveFixed = Replace(driveFixed, "\", String.Empty)
'Perform Query
Using querySearch As New ManagementObjectSearcher("SELECT VolumeSerialNumber FROM Win32_LogicalDisk Where Name = '" & driveFixed & "'")
Using queryCollection As ManagementObjectCollection = querySearch.Get()
Dim moItem As ManagementObject
For Each moItem In queryCollection
driveSerial = CStr(moItem.Item("VolumeSerialNumber"))
Exit For
Next
End Using
End Using
Return driveSerial
End Function
You will also need to reference System.Management in your project.
