Many computers contain readers for SD, MMC, SM, MS, CF, and other storage media
cards. These should be automatically detected and mounted. Here are some
troubleshooting steps if they are not:
Make sure that the card is put in correctly. Many cards look as though they are
upside down when correctly inserted. Also make sure that the card is firmly seated
in the slot; some cards, especially CF, require a small amount of force to insert
correctly. (Be careful not to push too hard! If you come up against something solid,
do not force it.)
Open Files from the
Activities overview. Does the inserted
card appear in the left sidebar? Sometimes the
card appears in this list but is not mounted; click it once to mount. (If the
sidebar is not visible, press F9 or click Files in
the top bar and select the Sidebar.)
If your card does not show up in the sidebar, press
CtrlL, then type
computer:/// and press Enter. If your card reader
is correctly configured, the reader should come up as a drive when no card is
present, and the card itself when the card has been mounted.
If you see the card reader but not the card, the problem may be with the card itself.
Try a different card or check the card on a different reader if possible.
If no cards or drives are shown when browsing the Computer
location, it is possible that your card reader does not work with Linux due to
driver issues. If your card reader is internal (inside the computer instead of
sitting outside) this is more likely. The best solution is to directly connect
your device (camera, cell phone, etc.) to a USB port on the computer. USB
external card readers are also available, and are far better supported by
Linux.
