Can any body help me in it?

Hi,my first 'suspect' usually is memory overflow, another one could be wrong wiring. In the latter case I would expect this already with sd.init.Maybe u want to check my blog posts on troubleshooting and memory consumption.http://robertgetzner.com/PersonalWordpress/arduino-sd-storage-troubleshooting-guidline-public-worldwide-collaboration/http://robertgetzner.com/PersonalWordpress/experiences-with-arduinosd-card-and-memory-consumption-now-it-works/Best, Robert
If I post only the parts whit SD use, can be?
Can I fix this memory problem?

However, if the program IS very large, and you are running it on a UNO, with 2K of SRAM, then the SD class is using 1/4 of that just for the buffer to write to the SD card. And it is very likely that you don't have enough memory.
You could upgrade to a Mega, or you could post your code. Posting your code is cheaper and quicker, but may not be the final solution. Upgrading may be required.
Paul, Do not take it personally, but I'm developing this commercial device for a client and I'm afraid to provide the code on the internet, I hope you understand me.
