Hi, my HDR has been working fine for about 18 months. Last week it displayed the message "disk needs to be formatted for access." and does not display any content. (There should be about 300GB of off-air TV.) I've tried powering down and re-booting with the same result. So far I've resisted the invitation to format the drive as I would like to recover the recordings if possible - what use is a PVR if you can't access the recordings? Everything else appears to be working normally. Have had no response from Humax support. Any suggestions please?
