If you aren't sure, insert the media and check the status messages in the system console window, as described in Step 3. If you need to format the media, go to How to Format a Removable Device (rmformat).
$ volcheck -v
Two status messages are possible:
Volume management detected the media and will attempt to mount it in the directory described in Using Removable Media Names.
If the media is not formatted properly, additional messages are displayed. You must then format the media before volume management can mount it. For more information, see How to Format a Removable Device (rmformat).
Volume management did not detect the media. Ensure that the media is inserted properly, and run volcheck again. If unsuccessful, check the media, which could be damaged. You can also try to mount the media manually.
$ ls /media/media-name
