I'm the maintainer of a (relatively) simple python utility called discspan[1] which I'd like to package for Fedora. It currently relies on HAL via dbus to determine when media is loaded and its capacity. I'm trying to remove the dependency on HAL since it's been depreciated for some time but the dbus UDisks interface seems to be lacking in several ways. For one, there doesn't appear to be an easy way to determine which devices are CD/DVD writers (or even readers). It has a boolean property called "DeviceIsOpticalDisc" that looked promising but it only reports true if the device is an optical drive AND there's a disc inserted. In HAL I used FindDeviceByCapability which narrowed things down. I've worked around that for testing the property "DriveMediaCompatibility" > 0 since it returns an array but this would also pick up flash card readers, zip, and jaz drives. I'll have to modify that to look for "optical" on the front of any members of the array. Second, I can not find any property that reports the disc capacity. The only property that looked close is "DriveSize" but for a blank disc this reports the same as the SectorSize, 2048. The documentation is horrible and the only reason I got this far was thinks to a howto[2] I found. Any pointers would be appreciated.
