1. Make sure the drive is not mounted with lsblk and umount

   umount /media/alan/<USB-DRIVE>
   

2. Run one of the possible commands as root, for example the cat command

   cat /mnt/storage/iso/file.iso > /dev/sd<LETTER>
   

   Do not append a partition number, so do not use something like /dev/sda1.

3. Run the sync command as root before removing the USB drive

   sync
