"Failed to create file. Card full?" What does this message mean? Today I wanted to see how long it would continuously record to 128gb CF card since I never shoot continuously longer than 4-5 minutes at a time and I was curious. After first 10 minutes or so, it stopped recording with this message so I turned it off and back on to try again and it stopped after around 10 minutes with the exact same message. Does anyone know what it is?
