Hi,
I have an increasing experience of SD cards blanking themeselves, and causing an error, during use - wonder if anyone else has had the same or similar?
The (3V3) Arduino is logging every 5 minutes and has the SD card mounted about 10cm from the Arduino itself - this is simply a card holder with the 6 important pins connected back to Arduino - 3V3, GND, MOSI, MISO, CS & SCK.
Everyting works fine, file creates, data is written etc but sometimes when coming back to it the card is completely blank and Arduino reports a write error - the data can be recovered with recovery software up to the point when the card caused an error..... hmmmm very puzzled - hopefully I have made a simple electonics mistake but look forward to thoughts.
