Ubuntu Jammy Jellyfish系统内置SD卡读卡器无法访问的问题排查求助

我目前在Toshiba Satellite L870-18V笔记本上使用完全更新的Jammy Jellyfish系统，配置是Intel Core i3双核4线程处理器+8GB内存。

我长期以来都遇到内置读卡器无法读取SD卡的问题，以下是相关排查信息：

系统与设备前提 #

• SD卡（带适配器）已完全插入内置读卡器插槽
• 已安装并更新到最新版本的udisks2包
• 系统使用systemd，因此用journalctl -b查看启动日志

启动日志（journalctl -b）相关报错 #

注：*1代表该行日志为黄色，*2代表该行日志为红色，是我自己标注的颜色提示

从以上日志能看出，系统识别出这是一张64GB的SD卡，也识别到分区sdb1，但手动挂载时出现问题：

手动挂载报错 #

尝试挂载到空目录/home/kub/fred时：

sudo mount /dev/sdb /home/kub/fred
# 输出：mount: /home/kub/fred: no medium found on /dev/sdb.

sudo mount /dev/sdb1 /home/kub/fred
# 输出：mount: /home/kub/fred: special device /dev/sdb1 does not exist.

疑问求助 #

以上情况是说明内置读卡器大概率存在硬件故障，还是有可能通过软件修复解决？另外，...error -71的报错是今天早上第一次出现的。
