Hi guys, I am new to my formuler z7+, I am all set up and can record onto my usb the first time I use it, unfortunately even when I am not recording its still flashing away, the next day when I try to record it wont work, so I have to erase and format the USB again before I can record again, I have a USB 3 128gb stick which I format in EXFAT due to me needing to record files over 4GB, can anyone offer me advice on what to do or what has worked for you? thanks for your help in advance
