do you mean the files are not complete or it's not overwriting the oldest file when the card is full?
sorry, I know English maybe not your strongest language so I'm just trying to make sure I understand the situation properly to give you some idea what to look at
I had one memorycard in my g90 that did just that, it worked just fine and made 5 min videos ok but when card got full it stop recycling.
That same card worked in my other camera.
Try some other memorycard, some brand name card maybe, i have used kingston cards.
