You need to be root. If you can using apt install konqueror (kde's file manager), you could launch konqueror as root by launching it in a terminal with the command "sudo konqueror" then navagate to your ipod. Unfortunately natalist will not launch this way, at least not since I last used gnome. Could also be that your permissions are wrong, try as root "chmod -R 777". Add the ipod at the last of the command like so. If the ipod is shown as sdc1 then use this "sudo chmod -R 777 /sdc1" . 8-)
