How do you save data from an Arduino-based device to a memory card? Fortunately, a microSD card and SD card breakout board now make this an easy task.

There’s also an SD card thrown in for good measure, making this one of the best tracking and data logging shields for the Arduino.

It turned out the SDIO mode on [Severin]’s card was broken, but accessing it with an Arduino and SPI mode worked. There was finally hope to get files off this damaged card.
