我有一個16Gb USB當我將它連接到我的電腦時，什麼也沒有發生。

  • 我嘗試使用 USB 找到我的 USB fdisk -l，但沒有出現
  • 我也嘗試過blkid，但它都沒有出現
  • 我也用過，gparted但是都沒有出現
  • dmesg我在連接 USB 後使用，這是輸出：

訊息輸出：

關於@Helio問題：

如果我的ls /dev/sdb輸出是：

/dev/sdb

如果我的fdisk /dev/sdb輸出是：

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

由於錯誤，這似乎是邏輯：

[sdb] READ CAPACITY failed

答案1

當然，每種情況都會有所不同，但我剛剛使用 USB 隨身碟時也發生過同樣的情況。我已經擁有它好幾年了，我經常需要拔掉/重新插入它幾次才能讓它工作。這次根本就行不通了。

我的解決方案是用酒精清潔驅動器的觸點。之後它就完美地工作了。

如果有幫助的話，以下是我遇到的一些錯誤：

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