USB 驱动器未安装/未检测到

在我的台式机上，我总是将两个 USB 端口插入我的两个外部硬盘。我有一个 16GB Kingstone USB 棒，我尝试将其插入另一个空闲的 USB 端口，但无法检测到它。我运行了fdisk -l并输出此

这也是我从 gparted 获得的信息 在此处输入图片描述

另外，在media文件夹中，我只能看到 2 个外部硬盘，而看不到 USB 驱动器。有什么可以帮忙的吗？

答案1

看来您的 USB 驱动器文件系统存在错误。如果您可以进入设备（此处/dev/sdd）已创建的状态，那么由于设备尚未安装，请e2fsck在其上运行以自动修复任何错误，例如

sudo e2fsck -y /dev/sdd

查看e2fsck手册页以了解描述和选项。如果e2fsck不起作用，请检查所有物理连接，包括 USB 电缆和链中的任何其他部件（如果有）。

答案2

您的系统是否检测到您的 USB 记忆棒？当您连接/断开记忆棒时，您应该会在内核日志中看到一条消息。您可以使用消息命令查看会发生什么。检查包含单词 usb 的行。

答案3

如果您卸载并随后拔下另外两个 USB 驱动器，或者甚至重新启动系统并将金士顿 USB 驱动器插入您知道可以正常工作的其中一个 USB 端口，这可能会有所帮助。

以下链接也许能帮助你分析这个问题。

无法格式化我的 USB 驱动器。我已经尝试使用 mkdosfs 和 gparted

  • 重新启动计算机并重试。
  • 断开其他 USB 设备，然后重试。有时 USB 设备可能会相互干扰功能。
  • 尝试其他 USB 端口和/或其他卡适配器。
  • 尝试另一台计算机。
  • 在另一台计算机上尝试另一个操作系统（Windows、MacOS）。您知道它在 Windows 中运行。

所以也许有

  • USB 端口问题
  • 由于连接的另外两个 USB 驱动器或者可能是其他 USB 设备而造成混淆。
  • USB 记忆棒和计算机的 USB 系统之间缺乏兼容性（硬件或软件问题）。
