我有一个 500 GB 的 USB 硬盘，NTFS 分区，昨天还能用，但今天就完全不能用了。它没有出现在我的 Ubuntu 机器上，现在是 Windows XP 或 Windows 7，我尝试了几种 USB 电缆和端口，但结果都一样。当我插入它时，灯亮了，磁盘旋转，所以我知道它“工作正常”，但它没有出现在 gparted、fdisk 或 lsusb 中。这是结果dmesg | grep -i usb：

这个硬盘上有一个非常重要的备份，无论如何，恢复它对我来说都至关重要。谢谢你的帮助。
答案1
您是否摔过磁盘或者以其他方式对其施加了重击，如果这样做，镜头可能会受损，您会听到磁盘旋转的声音，但无法读取它，因此不会显示在 gparted 中。
只是一个想法，除此之外我不知道为什么它不会出现。无论如何，祝你好运，我希望你能找到一种方法来访问你的备份
