Hi David,
Two of the three methods are mandatory.  The specific error code is not
mandatory.  Most people report 02/3A/00 when there is no media present.
ASCQ = 2 (tray open) is rare.

The drive is only required to return the media event block when a media
event has occurred.  So, the Tray/Door Open status can only be seen when a
media event is reported.

Mechanism Status gives static information and is useful at any time.

I think that both are useful, but if you wish to drop one, then it should be
the bit in the media event block.

Bill

Dear Bill, Dear MMC members,

Do we have a good reason to preserve the duplication of MECHANISM STATUS
command response "Door Open" bit and "Get Event/Status Notification" CDB
with a Notification Class Request of "Media" Door or Tray Open bit (bit 0 of
byte 5) in MMC5?

If we don't, maybe we can make one of the two obsolete and simplify both
host and logical unit implementation. Having 3 different reports of the door
status (sense code, mechanism status, GESN) isn't good.

Best regards,

David Burg

Wasim,
Try the MECHANISM STATUS command.  Its response has a "Door Open" bit that
should report the status you want.

Dear All,

Is there any way I could check whether a device tray is open? I have
tried ReadDiscInformation over an open try device and hoped that it
would return me error "MEDIUM NOT PRESENT - TRAY OPEN" but it always
return "MEDIUM NOT PRESENT".

With kind regards,
