我有一台 1TB WD Passport 外置硬盘。两天前它还在运行，而且状态良好（它是新的）。今天，我的硬盘在我的 Ubuntu 机器上无法被检测到。硬盘上的灯闪烁。我也将硬盘连接到另一台 Windows 机器，但那里也检测不到它。输出为lsusb：
Bus 002 Device 010: ID 1058:0810 Western Digital Technologies, Inc.
Bus 002 Device 006: ID 046d:c52b Logitech, Inc. Unifying Receiver
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
尽管这显示西部数据已列出，但硬盘并未作为文件系统安装在我的计算机上。我使用的是 Ubuntu 14.04。有人能帮我调试一下吗？
这是我从 dmesg 获得的信息：

如果是带有外壳的全新硬盘：将其退回商店并享受保修期内的新品。
如果您已将其自行安装到外壳中，请使用不同的 USB 端口/电缆，如果这没有帮助：请采用与上述相同的解决方案。
