我有一个 2TB 的外置 WD 硬盘，自从我在笔记本电脑上运行 Windows 以来，我就用它来备份和播放电影/音乐等。为了安全起见，我卸载了硬盘，并使用 smartctl 运行了一个简短的测试，结果显示已完成：读取错误 90%
$ sudo smartctl -l selftest /dev/sdc
smartctl 6.5 2016-01-24 r4214 [x86_64-linux-4.4.0-36-generic] (local build)

$ sudo ntfsfix /dev/sdc

我考虑过直接从终端安装驱动器，但我真的不能丢失此驱动器上的数据，也不想再犯错误。我该怎么做才能解决这个问题？请记住，我对 Linux 还很陌生。谢谢
答案1
我已修复该问题并安装驱动器。
发布我如何修复它，以防其他人遇到类似的问题。
我安装了 testdisk 并运行了它
sudo apt-get install testdisk sudo testdisk
并基本上按照说明进行操作，首先选择分析，这向我展示了问题并应用了修复。重新启动系统，外部硬盘运行良好。数据完好无损。
