I would like to burn a CD-R or DVD-R conventionally (normal TOC and filesystem for format). The content_hint property will be set so that my filter scheme matches and loads. On the disc, I would like to include a file containing a complete file system (not a Mac OS X disk image, since it needs to be mountable by Windows as well) that I will then export from my filter scheme to the rest of IOKit so that it is treated (eventually) as a file system that mounts in the Finder. First, do I just export an IOMedia object (what kind?) and set the content hint to <help me out here>? Obviously I can translate the read calls appropriately in my filter scheme to the underlying locations/track on the IOCDMedia or IODVDMedia object. Second, will this prevent the original IOMedia object's file system (9660 or UDF) from showing up in the Finder? I want to hide that file system, if possible, and I'm hoping this will accomplish that. Third, do I need to do anything special when I create this file? Any voodoo I need to be aware of? What I'm concerned about is the fact that it's on CD-R or DVD-R since there are special parts of the disc (TOC comes to mind) that I don't want people to try and read, since they're no longer meaningful. That makes me not want to export an IO[CD|DVD]Media object. Is it possible to do what I want? Is there a better way to accomplish this given the optical format's built in capabilities? The main constraint is that the file containing the file system I'm "exporting" should be readable (as raw data) if my filter scheme isn't present using the disc's normal filesystem. I'm intending on having the file entirely on it's own track, so that I can find the beginning of it from the TOC alone, without having to interpret the disc's filesystem. Is there anything there I need to watch out for here? A better approach I should be using? I'm finally getting towards the end of the up-front research for my filter scheme. I think this is the last major stone to turn... Thanks to everyone who has offered help/advice in the past. This email sent to site_archiver@lists.apple.com
