This kind of drive may do harm to your CD/DVD disc if you fail to operate carefully enough. However, software can command the drive to open/close its door. This is not what Sean wants. I want to tell Sean that he is not worth spending time in finding how to detect the open/close status of a drive door. If his program can open/close/lock/unlock the door and detect whether recording medium (CD/DVD) is present in drive or not and whether the drive is locked or not, that's enough, just as Nero (www.nero.com) can do.

Re: Questions about devices and input.
How about when media is loaded. I have a detection routine that'll ask for media, but what about when any media is loaded? Is there some kind of event or some way I can be notified.

The section 4.11.1 Removable Media Status Notification feature set of ATA/ATAPI-7 (http://t13.org/docs2004/d1532v1r4b-ATA-ATAPI-7.pdf) reads, d) Host system periodically checks media status using the GET MEDIA STATUS command to determine if any of the following events occurred: - no media is present in the device (NM). - media was changed since the last command (MC). - a media change request has occurred (MCR). - media is write protected (WP).
