Deek robot nano data logging shield
I was working on a project that involved the use of an SD Secure Digital card to log data into a text file. I was getting voltage levels that were withing the absolute maximum ratings of the SD card. I have some experience with Arduino in the past all good onesand I expected things to work out of the box.
But to my surprise I was mistaken. Then after some research I discovered that, the Arduino SD library is just a colorful wrapper for the SDfatliband the actual library has much more options and can be used to debug properly. When I tested the quick start sketch form the newly installed library, I got this error message.
One after the other I tried all their example sketches without any luck. Yet the problem persisted. I read in some forum posts that deek robot nano data logging shield resistive network introduces a latency in the SPI bus and could be the reason for the problem. So I decided to buy a low cost W Ethernet shield which has an SD card slot Image of which is featured in the heading of this deek robot nano data logging shield.
Most of the Ethernet shields have SD card slot, it would be deek robot nano data logging shield buying one without it. But again the problem was not solved. It took me a while to find out the solution. For Arduino Mega you have to do exactly the same ignore pin 53 completely though the comment asks you to change it to Good news is that you can add this line to all the code and it works perfectly fine atleast for me.

SD chip select is the key hardware option. Do not reformat the card! Is the card correctly inserted? Is chipSelect set to the correct value? It's set as an output by default.
