It sounds like you want someone to do all the work for you. Put a Button ,Textbox and a Listbox on a form and use the following:

Imports System.Reflection

Imports System.IO

Public Class Form1

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

' Find the first removable storage device and make this the initial

' directory if it exists

Dim allDrives() As IO.DriveInfo = IO.DriveInfo.GetDrives()

Dim d As IO.DriveInfo

For Each d In allDrives

If d.IsReady = True AndAlso d.DriveType = IO.DriveType.Removable Then

ListBox1.Items.Add(d.VolumeLabel).ToString()

If IO.DriveType.Removable Then

TextBox1.Text = d.AvailableFreeSpace

End If

Else

If d.IsReady = True And Not d.DriveType = DriveType.Removable Then

ListBox1.Items.Add(d.RootDirectory).ToString()

TextBox1.Text = d.AvailableFreeSpace

End If

End If

Next

End Sub

End Class

It's up to you to figure out how to get more info from IO.DriveInfo etc. Using System.Reflection.

you are going to have to use P/Invoke and RegisterDeviceNotification.
Here's a link to some code by Wei Mao at MS.

You'll need WMI for this. It will allow you to enumerate all removable
devices in the system and query their properties such as label, serial
number etc. If you want notification of when a drive is connected, WMI
should be able to handle that as well.

There is an excellent WMI plugin for the server explorer in VS.NET available
free on the MS website, it will assist in wiring up event code for WMI
classes.
