SD 卡 - 无法挂载/格式化/分区

SD 卡 - 无法挂载/格式化/分区

我有两张相同类型的 SD 卡:SanDisk Ultra UHS-I A1 32GB,
一张是全新的,另一张已经使用过。

两张卡在我的 ArchLinux 笔记本电脑(MacBook Pro 2013,系统是最新的)上都出现了相同的症状:

  • 它们显示为 /dev/mmcblk0,没有任何像 /dev/mmcblk0p1 这样的分区。
  • 因此我无法安装或格式化它
  • 当我使用 fdisk 创建分区时,我没有收到任何错误,fdisk 声称它已成功写入新分区表。但之后仍然只有 /dev/mmcblk0。当我再次运行 fdisk 时,它显示没有分区,但有 29.7GB 的未分区空间

由于一张卡是全新的,另一张卡被 Raspberry PI 使用时没有出现问题,所以我猜是我的系统出了问题,而不是卡的问题。
我还有其他来自不同制造商的 8GB SD 卡,它们在同一台笔记本电脑上运行良好。

任何帮助将不胜感激 :-)

编辑
经过大量的 Google 搜索后,我发现使用以下代码我可以创建分区、格式化和挂载它们。

rmmod sdhci sdhci_pci sdhci_acpi
modprobe sdhci debug_quirks2="0x04"
modprobe sdhci_pci sdhci_acpi

无论如何,当我将一些文件复制到其中并尝试卸载分区时,umount命令会卡住并且永远不会完成。当我弹出 SD 卡并再次安装时,没有文件放在那里。
