It's not a viable solution at all. There is no way from programming point of 
view to detect CD change request. If you think otherwise - send patches to

Windows does have a concept of mounting and unmounting disks. It is hidden 
from the user's point of view for Hard drives, CDs and Floppies, but clearly 
seen when using USB flash memory sticks for example, or other media that can
