Description Richard 2011-10-13 09:52:43 UTC 
Summary pretty much sums it up.

Why does the property 'DeviceIsOpticalDisc' require that media be inserted to be TRUE?

This forces me to check for the string 'optical' in the array 'DriveMediaCompatibility' to know if I'm dealing with an optical device.

I guess I can test for 'DeviceMajor' == 11, but that's not terribly intuitive.

The way to do this is to examine what kinds of media the drive is compatible with. In udisks 2.0 you'd look at this property

 http://udisks.freedesktop.org/docs/latest/gdbus-org.freedesktop.UDisks2.Drive.html#gdbus-property-org-freedesktop-UDisks2-Drive.MediaCompatibility

and see if any of the values in the array are prefixed with "optical". Closing WORKSFORME.
