Data recovery from a dead SD card using Arduino
A Secure Digital (SD) memory card is the most standard memory card for use in mobile electronic devices, such as cell phones, digital cameras, GPS devices, and tablet computers. Communication with an SD card can be done in one of two modes: the SDIO mode and the SPI mode. By default, the SD card operates in the SD mode, which is much faster than the SPI mode and is thus more preferable in the portable devices for achieving high-speed data transfer. If you have a damaged SD card that contains valuable information, this example shows you might have a chance to retrieve most of your data through an SPI interface using an Arduino board.
