WM_DEVICECHANGE (with DBT_DEVICEARRIVAL) works fine but is so slo-o-ow in
CD/DVD-rom case. It is not unusual to wait about 10 seconds between
injecting the tray and the moment apps finally recieves
WM_DEVICECHANGE/DBT_DEVICEARRIVAL notification. Is there any way for
user-mode app to get "earlier" notification about media insert/tray inject
event?
Many thanks!
Igor.

IIRC this notification (media insert) is sent by the FSD after mount only,
and mounting the CD can take seconds.

that is very well understood, and MSDN explicitely points out on this fact
in WM_DEVICECHANGE section. But my question was not about that :)
I was asking how is it possible (if possible) to get tray/media in change
event from user-mode app BEFORE(!) app receives
WM_DEVICECHANGE/DBT_DEVICEARRIVAL notification.
Many thanks!
Igor.

There was some named event which is signaled before the FS will mount. Use
WinObj to find the name.
