The Media Daemon

The Media Daemon

The Media Daemon (described in the mediad(1M) reference page) monitors the removable media devices on a system. When a tape, CD, optical disk, removable hard disk, or floppy disk is inserted, mediad recognizes it and mounts it as a file system if possible. Some CDs (such as audio disks), and some tapes and floppies (for example, tar(1) floppies) are not mountable, and mediad brings up an appropriate tool. When a user issues the eject command, eject sends mediad a message which causes it to attempt to unmount the media and eject it.
