How does Ubuntu mount a disc?

In most cases, the burned data CD is mounted on the computer running Ubuntu, and the disk character representing the disc appears in the File Manager. However, for unknown reasons, it is sometimes possible to put a disc in an optical drive that runs an Ubuntu computer and is not automatically mounted. At this point, using the command line to manually mount the disc, it becomes a necessary means.

1. Put the CD-ROM into the optical drive of the Ubuntu computer and find that there is no drive letter in the file manager. At this point, press the CTRL+ALT+T keyboard key combination to start the terminal, in which you type the following command: sudo mount/dev/sr0/mnt. This means that the Mount command will/dev/sr0 the device (that is, the optical drive) and mount it to the/mnt mount point.

2. After the command is executed, feedback "mount:/dev/sr0 is write-protected, mounting read-only" means that the disc is mounted in a read-only manner.

3. Open the File Manager, navigate to the "computer" in the left-hand navigation bar, and navigate to the/mnt folder in the right-hand window. At this point, you will see the files burned to the disc.

4, you can drag and drop through the mouse, or "copy", "Paste" and other operations, the CD on the file, copied to the computer.

5, file copy completed, and then back to the terminal, enter the following command: sudo umount/mnt. This means that the device under/MNT is unloaded with Umount.

6, if you do not perform the 5th step of the command, press the eject button on the optical drive, also can not eject the optical drive; only the Umount command is executed to eject the disc by pressing the button.
