WM_DEVICECHANGE is not receiving while inserting blank DVD ROM

Am facing a problem in WM_DEVICECHANGE. My win32 application not receiving the message when i insert blank DVD ROMS. the problem is only for blank dvds. (I got the WM_DEVICECHANGE on cds with and without data and DVDs with data. ) .

(1) Is der any need to give notification if yes what could be the class ID

(2) I want to find the type of cd is inserted ie is it a DVD(Empty or Not) or CD Rom (Empty or Not), the maximum data storage capacity etc . Which method to be followed to get this parameters.

Regards
