                Fix Ubuntu and other Linux slow/hanging file copying via USB.
              
          
        
      
        
  
      
    If your running a x64 bit Ubuntu or other Linux and find USB transfers hang at the end apply this fix:
echo $((16*1024*1024)) > /proc/sys/vm/dirty_background_bytes
echo $((48*1024*1024)) > /proc/sys/vm/dirty_bytes

To make this change persistant across reboots in Arch linux, create a file at /etc/sysctl.d/99-sysctl.conf and add these 2 lines:
vm.dirty_bytes=50331648
