How to solve the issue of files not being displayed while mounting a USB drive on Linux

If files are not displayed after mounting a USB drive on Linux, it could be due to one of the following reasons:

1. The file system of the USB drive is corrupted: try checking if the files display correctly on another device. If the files still do not show up on another device, it could be due to a corrupted file system on the USB drive. You can try using a file system repair tool (such as fsck) to fix the issue.
2. Permission issue with mounting point: It may be that the incorrect permissions are causing the files not to display. You can try using the command sudo chmod 777 mount point path to set the permissions of the mounting point to read and write.
3. Mounting option issue: The problem could be that the mounting options used when mounting the USB drive are incorrect, causing the files not to be displayed. You can try using the command sudo mount -o remount ,defaults /dev/sdX mount point path to set the mounting options to default values.
4. Issue with file system type: The problem may be that the file system type specified when mounting the USB drive is incorrect, resulting in the files not being displayed. You can try using the command sudo fdisk -l to view the partition information of the USB drive, and then mount it using the correct mounting command based on the file system type of the partition.
5. Hardware issue with the USB flash drive: If the above methods do not work, it may be due to a hardware problem with the USB flash drive itself, causing issues with reading files. You can try connecting the USB flash drive to another device to see if it can read files properly, or test with a different USB flash drive.

It is important to backup any important files on the USB drive before performing any operations to prevent data loss.
