Ok, looks like gudev is a dead end too. Problems: 1. No property which give media type. Instead it looks like there are boolean value given instead, i.e.: ID_CDROM_MEDIA_DVD_PLUS_R: 1 So I assume if I was using a DVD-R it would be: ID_CDROM_MEDIA_DVD_MINUS_R: 1 THIS IS CRAZY This means I would have to keep my own database of media types and check to see if any of the ID_CDROM_MEDIA...'s matched what's in my database. At least UDisks gave me a media type as a string. 2. Still no size/capacity property. So HAL is dead as of F16 but not fully replaced. I'll post all the properties at the bottom if anyone wants to wade through them.
