On Tuesday (after a DTV software upgrade), my 4TB external drive stopped working with my HR44-700 receiver. I wanted to run the disk utilities (by pressing select during reboot to go into advanced diagnostics), but virtually all of the testing options disappeared from the diagnostics menu. There was only 3 options with no submenus (clear cache, short SMART test and long SMART test). There used to be menus and submenus of tests. Guided diagnostics, disk utilities, etc. I've used them in the past to check my disk, etc. Very useful. Can I still access them some other way?
