I just placed my HDD in to my 7608NI-i2/8p and the beeping started as yours was. Sort of three long and two short. I was about to do something drastic as well. Then I saw your video. Very good Chris. Life saving (so to speak) - very much appreciated.. It is strange that Hikvision are still selling their 7600 series with the same issue after almost 3 years. Thanks.
