我正在尝试从文件系统损坏的 USB 驱动器中恢复文件，但到目前为止还没有成功。当将其连接到装有 Ubuntu 的机器时，我得到了以下信息：

我尝试过 testdisk 和一些数据恢复软件，但无济于事。
我希望有人能帮助我恢复此 USB 驱动器上的文件，也许借助这些日志文件。如果您能帮助我恢复此驱动器上的数据，我将不胜感激。
答案1
USB 错误 -110 意味着功率超出，计算机系统无法为 pendirve 提供足够的电力来运行。因此，该设备无法提供任何数据（即设备描述符），因此计算机无法识别它。
您的主板可能电力不足，或连接的设备太多。拔下电源一切然后将电脑从墙上拔下约 3 分钟，让 Mb 耗尽。重新启动，然后插入最少的东西再试一次。
有什么明显突出的地方吗？例如 240V 电脑上的 180V 电源？USB 连接针脚脏了？
否则，请尝试使用带有 USB 3.0 的朋友的计算机，我知道某些 USB 3.0 闪存盘无法在 USB 2.0 端口上运行。只是电力不够。
