最近我用 SSD 替换了我的内置 HDD，从那时起我的代码执行就很慢。
以前执行大约需要 5 秒钟，现在则需要大约 10 分钟。
当我从 grub 执行 fsck 时，显示以下结果：

要检查 Ubuntu 18.xx 分区上的文件系统...
- 启动至 Ubuntu Live DVD/USB
- 打开
terminal窗户 - 类型
sudo fdisk -l - 识别“Linux 文件系统”的 /dev/XXXX 设备名称
- 输入
sudo fsck -f /dev/XXXX# 用你之前找到的数字替换 XXXX - 如果有错误，请重复 fsck 命令
- 类型
reboot

我们决定最好使用 GPT 分区表重建系统磁盘，并全新安装 Windows 和 Ubuntu。备份失败和用户代码运行缓慢的问题已得到解决。
