使用“dd”格式化后无法安装 USB

我已使用 dd 格式化此 USB。此后，计算机未安装 USB。它被检测到，如下lsusb所示 samiron@samiron-Vostro-3558:~$ lsusb Bus 001 Device 002: ID 8087:8000 Intel Corp.

当我尝试mount以下错误时显示： samiron@samiron-Vostro-3558:~$ mount /dev/sdb1 mount: /dev/sdb1: can't find in /etc/fstab. 任何帮助恢复我的 USB 的帮助都将不胜感激

答案1

您需要提供一个挂载点：

mkdir /mnt/usb   ## Can be any directory
mount /dev/sdb1 /mnt/usb

您可以设置 /etc/fstab 条目以将您的设备映射到挂载点：

 /dev/sdb1   /mnt/usb                           ext4    defaults        1 2

通过该条目，您可以使用以下任何一项：

mount /dev/sdb1
mount /mnt/usb
mount -a   ## Mount everything in /etc/fsab
