It sounds as though the file system does not match against a media object in I/O Kit. We require the media object in order to request an ejection and also locate its icon. Does the disk in question not have a media object created for it? Does the file system talk directly to USB? I am porting a file system driver for magneto-optical disk drives from BSD to Mac OS X. Everything works fine at the BSD level. Disks will mount and you can read and write files to them and everything else you would normally expect to do. By creating an appropriate bundle in /System/Library/FileSystems I have got disks to automatically mount and appear as drives in the Finder. However, I have two issues: 1. The Finder will not eject disks when you ask it to. When you press the eject button next to the drive icon, nothing happens except any open windows displaying the content of the drive revert back up to the "computer" view. 2. The icon I am getting is the network drive icon. A USB drive icon would be more appropriate. The more pressing problem is the eject issue. How does the Finder notify the OS that a volume should be unmounted and ejected? This email sent to site_archiver@lists.apple.com
