Ever wonder how data recovery is done when an micro SD card fails? HDD Recovery Services shows us how he recovered the data. He uses 800 grit sand paper and wet sands the card till the card PCB pads are showing. He then micro solders wires from a memory reader directly to the SD card PCB. He is then able to pull the NAND flash data and save it locally. Not sure what he charges but based on the work that goes into getting it done it won’t be cheap.
