So, I have had my A119 hardwired and working perfectly for almost a month recording to a 64 GB G.Skill Class 10 card. I've even taken it out to view the recordings a couple of times and reformatted after each time with no problem. All of a sudden yesterday, I started to get the blue screen constant beeping to format the card (even though the card had not been removed). I followed the direction and formatted via the unit and it worked fine. Today, I got the same blue screen and beeping 5 min into my drive and then after reformatting, the same thing came up again after another 5 min! What is going on and how to resolve?
