# 读卡器问题

许多计算机带有读卡器，像 SD、MMC、SM、MS、CF 和其他设备存储卡的读卡器。它们应该会被自动检测并挂载。如果没有自动挂载，请尝试以下步骤来解决：

确保卡放置正确。许多卡正确插入时反面朝上。同时确保卡牢固地插在卡槽里；某些卡，尤其是 CF卡，需要略用力来插紧。(小心用力不要过大！如果觉得有很大阻力，不要硬插。)

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.

如果您看到了读卡器但没看到卡，问题可能在卡上。尝试其他卡或试试另一个读卡器。

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.
