在处理部分救援的分区后,我被告知要使用来ddrescue
保存发生故障的外部硬盘驱动器,然后应用testdisk
它来完成救援操作。尽管该驱动器几乎已完全保存到第二个驱动器上(由于我在特别讨厌的点击声中仓促删除并随后插入 Windows 分区),testdisk 似乎仍然将新驱动器视为“有缺陷”。更具体地说,Quick Search
仅返回少数文件夹和文件,而日志特别提到了Bad Relative Sector
.我想知道我应该采取哪些进一步的步骤,因为我被告知我现在的可能性是:
- 重做 ddrescue 尝试,让它完全完成并希望 testdisk 重新创建文件系统;
- 在救援的驱动器上使用 Photorec 并希望从中获取尽可能多的项目;
- 使用其他工具恢复我的数据。此外,我还被告知要寻求更详细的解决方案https://forum.cgsecurity.org/phpBB3/viewtopic.php?t=12307以及。
以下是 ddrescue 操作的日志摘录(完整日志太大,可以在此处找到https://pastebin.com/mCi0DgEi):

这里总结了我到目前为止所遵循的步骤https://archive.is/j66F9 非常感谢用户多德格因为在最初的问题中对我非常耐心。
答案1
重做 ddrescue 尝试,让它完全完成并希望 testdisk 重新创建文件系统
如果您仍然拥有生成的中间日志文件,ddrescue
您可以重新启动恢复过程,并且它将尝试从中断处继续。但是,如果您已经以任何方式更改了目标映像,那么这将显着降低您继续的机会,并且您应该考虑重新启动(使用新的日志文件)到新映像。
请注意,ddrescue
并不要求目标是设备 - 足够大的分区上的文件是完全可以接受的
