Object reference not set to an instance of an object.

Hey guys I'm making a function to retrieve all drives from a system and make a diskpart script for it. Problem is when I try to write the drive number to a text file I get 'Object reference not set to an instance of an object.' Here's my code. Friend Function CleanAllDrives() Dim drives As Integer = 0 Dim ord As Integer Dim order As String Dim query As New SelectQuery("Win32_DiskDrive") Dim search As New ManagementObjectSearcher(query) Dim info As ManagementObject ord = -1 For Each info In search.Get() Dim fs As StreamWriter order = ord + 1.ToString Dim random As String = "random" Dim script As String = "C:\\temp\\script.txt" My.Computer.FileSystem.OpenTextFileWriter(script, True) fs.WriteLine(order) fs.Close() Next Return ord End Function Any help is appreciated, I can't see where I've gone wrong. If I do Msgbox(order) it will popup for every drive in the system. Ignore the fact I have ord and order, they were used for debugging
