我不小心碰坏了一个 Seagatte USB 外置硬盘，上面有很多重要数据。连接正常，但它“停止响应”。我关闭了所有程序并重新启动。现在，当我连接硬盘时，dmesg 报告：

但 sdb 磁盘没有出现fdisk -l在sudo mount /dev/sdb /home/tcj/Desktop/seagate
挂起并且 gparted 永远“扫描”，但没有找到希捷硬盘。
有什么想法可以恢复我的磁盘吗？！
它被格式化为 ext4。
答案1
我在尝试双启动 Windows 7 和 Ubuntu 14.04 时遇到了类似的问题，在解决了几个问题之后，我终于发现，当 Windows 驱动器选择部分安装程序显示其中一个磁盘处于离线状态时，硬盘驱动器已经坏了。
我不是专家，但如果您的驱动器足够旧，这可能是可能的。我看过几个关于强制安装的帖子，以便获取您可能想要/需要的任何文件。
另外三件事：
- 将其他东西连接到该 USB 端口，看看是否还能正常工作
- 检查 USB 电缆是否已完全连接
- 如果你有使用相同电缆类型的设备，请将其连接并查看是否显示
