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:

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:
