Ubuntu 12.10 64 位似乎无法识别我的外部硬盘。它是 Vantec NST-310S3 外部磁盘盒，带有 WD 3TB 驱动器。磁盘有两个 NTFS 分区。我的 PC 是双启动系统。在 Windows 7 下，硬盘运行正常，但我无法让它与 Ubuntu 一起工作。当驱动器连接到 PC 时，命令sudo fdisk -l似乎永远挂起。
下面是没有外部驱动器和连接外部驱动器时的输出。我在最后还添加了 dmesg 命令的最后几lsusb行。cat /proc/partitions
首先没有驱动器：

答案1
USB 3.0 设备未提供延迟信息。
当您连接 USB 设备时，内核会提供 10ms 的延迟来让设备初始化，然后内核开始向设备发送命令。
对于 USB2.0 设备，延迟被硬编码到内核中，但对于 3.0 设备，该值是可配置的并由设备提供。
如果设备不为内核提供延迟值，内核将永远不会向驱动器发送命令，因为它将永远等待。
解决此问题的唯一方法是获取不同的驱动器外壳（您的驱动器外壳坏了）或修补内核以使用 USB3.0 中的默认延迟，这将非常困难并且还可能破坏其他东西。
答案2
我以前遇到过类似的问题。
启用 ehci 切换并在 bios 中启用旧版支持。
还可以尝试在 3.0 端口中使用 USB 2.0 集线器，并将驱动器放入其中（为了进行故障排除）
确认您的 3.0 总线板上没有额外的电源连接器；它就像一个 4 针的。（有时会发生） - 因为，如果我没记错的话，如果没有那个电源连接器，它仍然会使用低功率 USB 设备，但不会使用高功率硬盘。（正确）
希望这里有些东西可以帮助到你。
