Retrieve information on all available drives

You can retrieve information about all the available drives using calls to Windows API, if you like the hard way of doing things. A much simpler solution is offered by the Microsoft Scripting Runtime library, that exposes a Drive object that lets you get all those info by querying a property:

' NOTE: this code requires that you add a reference to the'       Microsoft Scripting Runtime type libraryDim fso As New Scripting.FileSystemObjectDim drv As Scripting.DriveDim info As StringFor Each drv In fso.Drives    ' display drive name and type    info = "Drive " & drv.DriveLetter & vbCrLf    info = info & "  Type: "    ' we must decode this value    Select Case drv.DriveType        Case Removable: info = info & "Removable" & vbCrLf        Case Fixed: info = info & "Fixed" & vbCrLf        Case CDRom: info = info & "CDRom" & vbCrLf        Case Remote: info = info & "Remote" & vbCrLf        Case RamDisk: info = info & "RamDisk" & vbCrLf        Case Else: info = info & "Unknown" & vbCrLf    End Select    If Not drv.IsReady Then        ' if the drive isn't ready we can't do much more        info = info & "  Not Ready" & vbCrLf    Else        ' retreive all additional info        info = info & "   File System: " & drv.FileSystem & vbCrLf        info = info & "   Label: " & drv.VolumeName & vbCrLf        info = info & "   Serial number: " & drv.SerialNumber & vbCrLf        info = info & "   Total space: " & drv.TotalSize & vbCrLf        info = info & "   Free space: " & drv.FreeSpace & vbCrLf    End If        ' do something with the gathered info    ' (display in a textbox in this case)    Text1.Text = Text1.Text & infoNext
