They will be ignored. I'm interested in mounting the ISO/Joliet part of a hybrid CD-ROM. I can sort of get it to work using commands like: Then the volume is shown by mount and seen by Carbon's FSGetVolumeInfo, but it is not shown in the Finder or listed by either of If you do "open /Volumes/Foreign", you'll trigger the Finder process' Carbon File Manager cache to "see" the filesystem, and will show an icon in the sidebar. I have the impression that this has something to do with disk arbitration, not that I fully understand what that means. I tried mounting the volume using the function DADiskMountWithArguments, but apparently it only allows the -o arguments to mount, not the -t arguments. Anyone have any wisdom to share on this? You cannot force a file system, nor can you convince DiskArbitration that there's anything to mount on disk1s1, because of the way it probes media. By the way, mount shows the HFS part of the CD as /dev/disk1s1s2, but the ISO part as /dev/disk1s1. This offends my sense of symmetry. I would expect that the two file systems would be at the same level of the hierarchy. Not that I know what those s's and 1's and 2's really mean. Actually, they are symmetric. The ISO "filesystem" takes up the entire media (disk1s1). disk1 represents the entire CD, and disk1s1 is the first session. On disk1s1, there are two overlapping containers. The ISO "filesystem", and an Apple Partition Map. The Apple Partition Map further publishes several slices corresponding to each partition in the map. That's where disk1s1s2 comes from. The ISO filesystem and APM are peers, and symmetric. Running "ioreg -l" or IORegistryExplorer.app may be instructive. What is your higher level goal? If you want two things to show up in the Finder, you may want a multi-session disk with two Apple Partition Maps, or a single session with a multi-partition map. You cannot do the former with ISO content, though. If you are trying to preview the ISO content of your hybrid, the manual mount is your best bet.
