Solution to unreadable USB flash drive data in Linux

Solution for reading data from a USB flash drive in Linux-General Linux technology-Linux technology and application information. for details, see the following. This problem occurs only in earlier Linux versions.

Because older Linux systems are not like Windows systems, they can be automatically identified after new hardware is connected. in Linux, new hardware cannot be automatically identified and must be manually identified. USB mobile storage devices are generally identified as sda1, which can be queried by the fdisk-l command.

Before using a USB flash drive, we need to create a new sub-directory for the external mount point. Generally, the subdirectories of the external mount point are created in/mnt, and we also created there, of course, you can also create a directory in the/directory and set the name by yourself. we will name it usb. The Command under the terminal is as follows:

Mkdir/mnt/usb

Then we can connect to my USB flash drive, and then Enter the command at the terminal and press Enter:

Mount/dev/sda1/mnt/usb

In Windows, when the USB flash drive is used up, we need to delete it before removing the USB flash drive. in Linux, we also need to delete the mount point by using the following methods:

Umount/dev/sda1/mnt/usb or umount/dev/sda1

If you do not detach a USB flash drive to umount, data may be lost.
