SD 卡读卡器不工作 - Ubuntu 20.04

Question

我有新安装的 Ubuntu 20.04。如果与 SD 卡适配器一起使用，则无法访问任何 SD 卡。我尝试了多个适配器，并在其他计算机上进行了相同的测试。SD 卡或适配器在其他系统上运行良好，但在我的系统上无法识别。

如果我使用 USB 适配器，我可以访问 SD 卡。

这绝对不是硬件问题，因为如果我在计算机上的 Windows 分区上打开，我就可以访问它。

这是可用磁盘列表的屏幕截图，其中 SD 卡已插入 SD 卡适配器：

它是一个简单的存储设备，如果我在 Windows 分区上打开它，那么它很容易打开，但在 Ubuntu 上。

一些论坛建议我重新安装udisks2，我照做了，但并没有解决问题。

sudo apt-get install --reinstall udisks2

我该如何解决 ？

编辑：正如评论中所建议的，我使用 GParted 来获取更详细的信息，这是启动 GParted 后的结果：

Edit2：我运行了命令lspci，然后lspci -v | grep -iA15 sd这是输出：

Answer 1

Unix 新手，但我使用了上面列出的命令（lsusb、lsblk、DISKS），这些命令确认闪存卡实际上已被笔记本电脑看到。唯一的问题是文件看不到它，即使它已格式化。DISKS 注意到闪存卡上没有分区，所以我让它创建一个分区（确定整个 (16 GB) 将是一个分区。这修复了它，文件现在可以访问它。它的作用就像任何驱动器或 USB戳。
