我在 Dell Latitude E7470 笔记本电脑和 LITEON CV3-8D128 SSD 上使用了 4 年多的 Ubuntu 20.04.2 系统现在在使用大约 15 分钟后切换为只读。
症状是：
- 由于“输入输出错误”，所有命令都失败
- 所有图标消失
- 基本上什么都不起作用
- 有时桌面甚至消失，控制台打印“systemd-journald：无法写入条目，忽略：只读文件系统”。
我累的是什么：
- 救援模式：我不能，
fsck -f /dev/sda6因为据说它是“已安装”（或当我尝试卸载时为“活动”） - Live USB：我经常看不到整个 SSD 又名
/dev/sda，parted甚至lshw不能真正看到fsck - 双启动Windows：我从不使用这个分区，但有趣的是我可以
sda6从我的Windows双启动中看到该分区（并恢复数据）。
看起来是硬件故障吗？我在启动 Windows 时可以读取整个磁盘，但可能存在写入错误，导致系统在 Linux 下切换到 RO 模式？
多谢 ！
编辑：
我刚刚在附近的另一个分区（位于同一个 SSD 上）安装了一个新系统（Ubuntu），似乎没问题：过去 24 小时没有问题，而另一个系统在大约半小时内出现故障。
