By design (very simple design ;-)) the x-surf IDE ports only works with some (a few) IDE Hard Disks. If I remember well what is written in the X-Surf "manual (:rtfm:)" it's a timing issue.
HDtoolbox should show you a list of devices availlable if you set the "ASKDEVICE" tooltype in its icon. so you should see both x-surfide.device and x-surfatapi.device if the binddrivers have been succesfull. :-)
