I've had this problem on my s970 for years, but my patience has given out and I need help. I'm recording something, typically me singing to a song, Suddenly, a message flashes on to the display, "The USB flash drive cannot be used temporarily." No hint as to why or when, just accept it and try again. I am unable to correlate the failure to any factor in what I'm doing or when it happens.
Am I the only s970 owner who suffers from this?
