I have a Digital 4K video camera recorder, and I have tried two different types of SD cards it's telling me its still locked. I pushed the switch and tried to format it but will not let me keeps saying memory card locked. Was wondering if I can do something with the camera that I have to fix it or need to bring it in and have someone fix it. Id likes to solve this on my own first before taking it in. Please help. i am using this for my business.
