Well I'm not surprised with this as I had one and it literally seem to have been destroying itself even when I kept it unplugged. There was just a lot of activity going on and eventually just destroyed the hard drive in it. Not to mention when I asked the manufacturer about any firmware updates they basically said that they didn't have any. Keep an eye on dvr's becuse they are as bad as android phones that don't get any updates. A lot of people and companies used them but they seem to be one of the worst pieces of equipment to get any updates as well.
