我有一张微型 SD 卡，我的笔记本电脑无法读取该卡，也无法安装或显示在lsblk或 中blkid。使用tail -f /var/log/syslog，表明存在问题：

我尝试了几件事（例如sudo apt-get install exfat-fuse exfat-utils）或添加tifm_sd到/etc/modules.，他们都没有成功。 SD 卡（Sony micro sd、HC、16 GB、90 MB/s、SR 16UY3 在我的 Android 手机和相机中运行良好，但在我的笔记本电脑（Ubuntu 18.04、Acer TravelMate 4500）上运行不佳。格帕特，我看不到卡片。其他 SD 卡在笔记本电脑上工作正常。
有关 SD 卡读卡器的信息（我还更新了驱动程序以排除可能的原因）lspci：

这是一台相当老的笔记本电脑：根据 Google 的说法，它似乎配备了 2004 年 6 月发布的 Pentium M 715 CPU，以及 2003 年发布的 Intel 855GME 芯片组。
SDHC存储卡子类型的规范于2006年公布，因此笔记本电脑中的内置读卡器很可能太旧而无法支持SDHC卡：SD卡子类型很可能不支持甚至在设计笔记本电脑的读卡器芯片时就已经存在了。
SDHC规格重新定义卡的卡特定数据寄存器的使用方式：这往往会导致较旧的读卡器无法识别 SDHC 卡，除非读卡器有固件更新。
