hey does anyone know witch of the eight pins on a micro sd card if bombarded with 5volts will corrupt all data or erase or just render the chip unreadable was thinking pin 6 (ground) and pin 7 (data out) but dont really want to test on one of my cards and no im not looking to be able to use again just looking for a data erase fail safe. i guess id have to run a diode as to not burn out the device while still rendering the data from being usable what size of diode would be suitable for this? also which pin on a sim card would have the same effect rendering no readable data?
