I had not remove memory card from the cpu and i had not donwload the program. There wasnt any error in the cpu. I want to know, what are the possible reasons for data reset in memory card? and is there any way to store the data permanently in the program?

I heard something like EMC could be the problem. But perhaps someone else has a better explanation Best regards, Wizard
