我有一台双启动笔记本电脑(Ubuntu 12.04.4/Windows 7),硬盘出现故障。SMART 当前待处理扇区数已开始上升,系统在 Ubuntu 和 Windows 中启动都需要几分钟。我用另一个容量相同(750GB)的磁盘替换了该磁盘,并尝试使用 dd 命令将所有内容传输到新磁盘。
Ubuntu(逻辑)分区消失了,其先前占用的空间现在显示为扩展分区内的 RAW 空间。我决定重新安装 Ubuntu(14.04),它运行正常,只是它不再提供在 Windows 7 中双启动的选项。在安装过程中,它说没有找到其他操作系统。
奇怪的是,NTFS 分区在那里,它安装在 Ubuntu 中并且可以访问文件。在硬盘克隆期间出现了几个错误,但第一个错误是从 Windows 分区开始的 28GB 左右,所以我猜它不可能对文件系统造成严重损坏。以下是我尝试的一些实用程序的输出:
sudo fdisk -l

Windows 7 分区为 /dev/sda2。gparted 工具中有一个感叹号,并提供以下信息:

我也尝试了 ntfsfix,但没有写任何东西:
ntfsfix -n /dev/sda2

最后是 ntfsresize:

修复分区并使系统再次可双重启动的最安全方法是什么?我没有 Windows 7 DVD,因为我的笔记本电脑在磁盘末尾有一个小的隐藏分区,可用于在发生故障时恢复所有内容,但现在已严重损坏。
答案1
我建议你使用 Windows 恢复光盘。你可以从各种来源(合法)获取这些光盘,但要小心一点——互联网上的随机网站可能有合法软件,也可能含有病毒。请先与 Microsoft 核实。(不过,我没有直接的 URL 可以分享。)这样的磁盘应该能够修复文件系统损坏,前提是副本足够好,分区的内容没有完全被破坏。
