我有一个16Gb USB当我将它连接到我的电脑时什么也没有发生。

  • 我尝试使用查找我的 USB fdisk -l，但它没有出现
  • 我也试过了blkid，但似乎也没有
  • 我也用过，gparted但似乎也没有
  • dmesg我连接 USB 后使用，这是输出：

消息输出：

关于@Helio 问题：

如果我的ls /dev/sdb输出是：

/dev/sdb

如果我的fdisk /dev/sdb输出是：

fdisk: unable to read /dev/sdb: Invalid argument

由于错误，这似乎是合乎逻辑的：

[sdb] READ CAPACITY failed

答案1

当然，每种情况都会有所不同，但我刚刚在 USB 闪存盘上也遇到了同样的问题。我已经用了好几年了，我经常要拔插好几次才能让它工作。这次它根本就不能用了。

我的解决方案是用外用酒精清洁驱动器的触点。之后它就正常工作了。

如果有帮助的话，以下是我遇到的一些错误：

[47908.871713] usb 3-1: can't set config #1, error -71
[47924.750591] sd 5:0:0:0: [sdc] READ CAPACITY failed
