我有 2TB Wester Digital 外置硬盘。我将其连接到安装了 Ubuntu 14.04（64 位）的笔记本电脑上的 USB 3.0 端口。直到昨天它都运行良好（没有尝试过其他操作系统）。在移动一些文件时，它冻结了我的操作系统，我不得不硬重启我的笔记本电脑。从那时起，nautilus 就不再显示硬盘了。
我尝试了 SU 和其他论坛上提供的几种解决方案，但都无济于事。然而，它曾经通过 2.0 端口被检测到，但几乎所有目录都是空的，但预期的空间仍然被占用。我重新启动了 Windows 以运行 chkdsck，但我的电脑没有显示它。虽然磁盘管理器显示了它，但它显示“磁盘需要初始化”。如果我尝试执行相同操作，它会退出并显示“I/O 设备错误”消息。我在 Ubuntu 中再次重新启动，但仍然看不到它。消息还提到了 I/O 错误和机箱错误。磁盘和电缆状况良好（我才 12 天前买的）。
它仍然显示在 lsusb 和磁盘中，但不显示在 gparted 和 fdisk -l 中，它们仅显示内部硬盘驱动器。
请帮忙，因为磁盘包含我不能丢失的重要数据。
以下是 lsusb、dmesg 和 fdisk -l 的日志。

如果有帮助的话，VLC Player 过去在直接从外部硬盘播放某些文件时也出现过 I/O 错误。
任何帮助都非常感谢。
答案1
驱动器的具体型号是什么？你听到任何异常声音了吗？我会在 Windows 系统上试用驱动器，看看它是否在 BIOS 中被检测到，装置经理或磁盘管理以及如何（屏幕截图会很有用）。
我也会尝试跑步WD Data Lifeguard 诊断工具并查看它是否识别该驱动器。如果可以，我会查看该驱动器是否通过了快速测试和扩展测试。
您是否在其他系统上尝试过该驱动器？
