我的旧笔记本电脑有操作系统启动相关问题。它无法启动之前安装的 Windows 10，所以我决定安装 Linux Mint 20。但出了点问题。我得到了答案，I/O error at /dev/sda我认为这一定是硬盘问题。我重新启动了笔记本电脑，运行 Linux Live CD，在出现一些新的内核异常和警告后，它终于启动了。
我想在检查badsector后进行修复，但从未找到硬盘。我用过下一个，但它也没有找到任何硬盘。我很困惑，所以我认为使用硬盘驱动器进行清理是个好主意（如果它找到任何硬盘驱动器，它就会成功）。所以我正在做那个该死的清理工作，但新的smartctlfdisk -lGParted Livedban例外发生了。我这里有一些日志。

我想，嗯，我不知道出了什么问题。又一个 I/O 异常？可能是由 CPU 过热引起的（我收到了很多带有该警告的事件，或者是因为 HDD 坏了）或者只是坏扇区问题。
接下来我找到了 FreeDOS 1.2 可启动映像，复制/粘贴了HDAT2 7.0要修复的程序，将其安装在我的 USB 设备上，实际上笔记本电脑正在运行在验证/写入/验证模式下检查和修复 HDAT2 坏扇区。
晚上，我来看结果，但它只检查了2.89MB在8:16小时并且任何这些被检查的扇区都被标记bad sector为无法纠正的数据错误或者未找到地址标记。警告。经过一些计算，我意识到这个操作将需要大约 100 年才能完成，因为硬盘容量为 320GB。而我没有那么多时间。
我真的想找到一种方法来解决它，所以如果你知道我该怎么做而不是等待 100 年，我会很感激。
