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).

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 drive may not even have a door. Mr. smo/rgrav loves playing joke very much. No. Unlike you, I know what I'm talking about. But most of CD/DVD drives have a door, though generally speaking, software cannot detect the open/close status of a door directly. http://www.plextor.com/english/products/716AL.htm What I said is "most of". 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.

Questions about devices and input.
I'm writing some cd buring software using burncd as a reference. I was wondering if its possible to detect opening and closing of the doors. I don't see it very often in unix. i wrote a media detection routine but it'd be nice to detect when the door is opened and when its closed so I'm not polling and praying. Excuse my ignorance in advanced. I've been looking I just can't seem to find any information on obtaining this kind of information. -- Sean Bryant ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
