afyb 0 Posted October 28, 2014 Hi, I have this DVR but I can't get it to record and erase old files, so every month the alarm goes off and I have to manually format the HDD, does anyone know this DVR and perhaps a quick step by step so I can change it so it records automatically after 30 days? Maybe I need a f/w upgrade? Share this post Link to post Share on other sites
