Hi, new to the forum but hope you can help. Not used the box for a while, started up, had a few old recordings, but they disappeared (reappeared after Factory Reset), now disappeared completely. Also it just will not record, we’re thinking a problem with hard drive & seem to recall Humax support (when I called after software update stopped live TV pause) suggesting reformatting. How do we reformat the hard drive, or, has anyone got any other suggestions please?
