在我的 Ubuntu 19.04 中，系统自动进入只读模式。我使用修复了这个问题，
fsck /dev/sda7 -y
但是这个问题并没有永久解决，过了一段时间后它又进入了只读模式。
我使用的是安装了 Windows 10 的双启动系统。这是磁盘的信息
这是磁盘信息的导出，包括 SMART 信息

让我们采用双重方法来解决您的问题......
记忆测试
去https://www.memtest86.com/并下载/运行他们的免费记忆测试来测试你的记忆力。至少完成一次所有 4/4 测试以确认记忆力良好。这将需要很多小时才能完成。
硬盘坏块
注意：如果您的硬盘出现故障，不建议在没有任何备份的情况下执行此过程。即使备份到 USB 闪存驱动器也比没有备份要好。
这些是我正在查看的重要数据点...

注意：不要中止坏块扫描！
注意：不要对 SSD 造成坏块
注意：请先备份您的重要文件！
注意：这将花费很多小时
注意：您可能面临硬盘故障
启动至 Ubuntu Live DVD/USB。
在terminal...
sudo fsck -f /dev/sda7# 首先清理文件系统
sudo fdisk -l# 识别所有“Linux 文件系统”分区
sudo e2fsck -fcky /dev/sda7# 只读测试
或者
sudo e2fsck -fccky /dev/sda7# 非破坏性读写测试（受到推崇的）
-k 很重要，因为它会保存之前的坏块表，并将任何新的坏块添加到该表中。如果没有 -k，您将丢失所有之前的坏块信息。
-fccky 参数...
-f Force checking even if the file system seems clean.
-c This option causes e2fsck to use badblocks(8) program to do a
read-only scan of the device in order to find any bad blocks.
If any bad blocks are found, they are added to the bad block
inode to prevent them from being allocated to a file or direc‐
tory. If this option is specified twice, then the bad block
scan will be done using a non-destructive read-write test.
-k When combined with the -c option, any existing bad blocks in the
bad blocks list are preserved, and any new bad blocks found by
running badblocks(8) will be added to the existing bad blocks
list.
-y Assume an answer of `yes' to all questions; allows e2fsck to be
used non-interactively. This option may not be specified at the
same time as the -n or -p options.
