Ubuntu 14.04 無法辨識 USB 驅動器

我有一個 16GB Hama USB 棒，我在 Ubuntu 14.04 上使用它。直到昨天它還運作得很好，但是我的 Linux 崩潰了，我不得不使用低圖形介面在上面複製一些檔案。無論如何，複製文件並重新安裝系統，但現在我看不到我的驅動器。任何其他驅動器都可以工作。

這就是我得到的dmesg | grep -i usb

這就是我得到的lsusb

這就是我得到的lsblk

您知道我的驅動器發生了什麼事嗎？

答案1

由於您的隨身碟在「磁碟工具」中可見且

mount /dev/sdb /mnt

命令返回

mount: /dev/sdb is not a valid block device

因此，您的作業系統可以偵測到隨身碟。

現在，打開終端機 ( ++ Ctrl)並輸入命令：AltT

sudo su

以獲得root權限。

接下來，輸入：

mkfs.xfs /dev/sdb1 && mount /dev/sdb1 /mnt -t auto

這就得解決問題了。但如果沒有，請在下面發表評論。謝謝你！

答案2

確保使用DD正確的設備，而不是將實際系統清除

將您的 USB 裝置完全歸零

dd if=/dev/zero of=/dev/sdX bs=4M

然後使用您選擇的磁碟實用程式建立一個分割區 ( fdisk /dev/sdb)

然後格式化分割區

mkfs.vfat /dev/sdb1
