VB.Net How to get the Drives and their Type. Here is code under the Button1.Click event Sub.

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
    Dim allDrivesDriveInfo As System.Collections.ObjectModel.ReadOnlyCollection(Of System.IO.DriveInfo)
    allDrivesDriveInfo = My.Computer.FileSystem.Drives
    'Another way to get the Drives is:>>
    Dim myDrives() As System.IO.DriveInfo = System.IO.DriveInfo.GetDrives
    For Each d As System.IO.DriveInfo In myDrives
        Select Case d.DriveType
        Case System.IO.DriveType.Unknown
            'Your code here.>>
        Case System.IO.DriveType.NoRootDirectory
            'Your code here.>>
        Case System.IO.DriveType.Removable
            'Your code here.>>
        Case System.IO.DriveType.Fixed
            'Your code here.>>
        Case System.IO.DriveType.Network
            'Your code here.>>
