sample code to reproduce the problem.

         DriveInfo[] dl = DriveInfo.GetDrives();
                foreach (DriveInfo d in dl)
                {
                    if (d.IsReady)
                    {
                        Console.WriteLine("label " + d.VolumeLabel + " name " +
d.Name + " driveformat " + d.DriveFormat + " totalfreespace " +
d.TotalFreeSpace + " TotalSize " + d.TotalSize);
                   //     Console.WriteLine("Disk Check " +
d.AvailableFreeSpace / 1000000000);
                    }
