So I am waiting for some feedback from experienced users with USB charging during recording and never-bricked-card.
It was also mentioned about the use of regular USB data
cables possibly being part of the problem, as opposed to the two-wire external power cables (with standard USB plugs) that come with the camera specifically for external power use. People are using a wide gamut of external USB power supplies with who knows what kind of cables with the cameras. I have bricked one of two identical cards (Sandisk 8GB CL6), but not the other, and I don't know what I was doing when it happened. I've used external power from both the PC with both data and power only cables, and a home-made 4-cell AAA battery pack with a dedicated two wire mini-USB plug for the camera. So until we know what the root cause is, knowing which cards haven't been bricked doesn't tell me anything definitive.
