Our DishTV T1050 seems to have lost some disk space down the back of tv cabinet. We're always hovering about 1% despite deleting a pile of content and the amount seems to disappear unusually quickly when we free up space. (both HD and SD).

Are there any disk tools in a secret menu anywhere that can do a clean up (or is there the nuclear option of an HD reset if not).

Can't see any mention of this on the DishTV, and the box is out of warranty.
