No. I mean when I insert a new CD in CD drive and when I remove the CD from CD drive by pressing 'eject', then I could not see 'mount/umount' events respectively.

You mean your manual umount/mount events or what? If you don't do automatic 
mount handling you can't IMO see anything, since then nobody mount/umount.

Depends on your setup. You can use automount or HAL or both ...
