Removable drive events?

Morning...

I have spend a silly amount of time googling this, and decided this was the only place I am likely to get an answer...


Is there an event that I can hook into that will alert me when a Removable Drive is either added or taken away?

Also, it would be really useful to find out what the drive letter is...

TIA

Good question. I did a bit of searching and found this:

Apparently there is a WM_DEVICECHANGE message, which would be handled via a wndproc function (in C/C++). I haven't actually tried this, however...but it looks interesting.

Sorry about the formatting, and that it is only snippets but it is ripped out of some code that I was playing with based on a sample I found from somewhere.  Sorry I can't post the attribution

static readonly int WM_DEVICECHANGE          = 0x219;
static readonly int DBT_DEVICEARRIVAL        = 0x8000;
static readonly int DBT_DEVICEREMOVECOMPLETE = 0x8004;
static readonly int DBT_DEVTYP_VOLUME        = 0x00000002;

  [StructLayout( LayoutKind.Sequential )]
    public struct DEV_BROADCAST_VOLUME
    {
        public int dbcv_size;
        public int dbcv_devicetype;
        public int dbcv_reserved;
        public int dbcv_unitmask;
    }


 protected override void WndProc(ref Message msg)
        {
                if( msg.Msg == WM_DEVICECHANGE )
                {
                    if( msg.WParam.ToInt32() == DBT_DEVICEARRIVAL )
                    {
                        int devType = Marshal.ReadInt32( msg.LParam,4 );
                        if( devType == DBT_DEVTYP_VOLUME )
                        {
                            DEV_BROADCAST_VOLUME vol;
                            vol = (DEV_BROADCAST_VOLUME)Marshal.PtrToStructure( msg.LParam,typeof( DEV_BROADCAST_VOLUME ) );
                        }
                    }
                }

            base.WndProc( ref msg );
        }
