I will try to disable and enable that at File Write. but this seems to be a problem. As I am receiving data continuously and processing that in 10ms (which takes 1us. Data rate is 6000 samples/second)
    What would happen if you get an interrupt 11 whilst the program is actually writing the file (as the time it takes to write/flush the file is not constant and can vary)? Are you using single or double buffering?
