Topic: What Happens if an arduino hits the maximum storage size on an SD card? (Read 374 times) previous topic - next topic


So pretty much I had a Adafruit Feather 32u4 Adalogger with a 10 DOF sensor in it. I put it in a rocket and launched it off. I couldn't find the top part yet and it is probably still logging data. What happens when the 2 GB SD card can't store any more data. Will it overwrite or will is just stop recording?

Will it overwrite or will is just stop recording?
It will fail to write.
The art of getting good answers lies in asking good questions.


Supplementary question: is there an absolute maximum size of microSD that the Arduino SD readers and associated library can handle? If so, what happens if you use a card that's too big? Does it use up to where it "understands" or just not work at all, or what?
