如何读取损坏的光盘

我有一张损坏的迷你 DVD，它曾用于摄像机。它似乎已损坏（无法在摄像机上播放）并且无法打开。我不知道该如何修复它。有办法吗？

答案1

我会尝试使用sudo dd if=/dev/cdrom of=dvd.img/dev/cdrom （其中 /dev/cdrom 是您的驱动器设备路径）。这将创建光盘映像，并尝试在此过程中恢复数据。然后您可以尝试testdiskdd 生成的映像是否是垃圾。

答案2

它可能不在 /dev/cdrom 下，因为它没有被安装为 /dev/cdrom。

这样做：取出迷你光盘并运行mount，再放入并mount再次运行。有什么不同吗？如果有，你可能很幸运。如果是这样的话，你应该能够dd搞定一切。
