Whether you're using a digital camera, PDA, or smartphone, there's a good chance much of your device's information is stored on a small plastic SD (Secure Digital) card. So if you've found yourself with a damaged or cracked card, you may think that all your digital information is lost. This isn't necessarily true. There are ways to fix the SD card yourself, and there's no technical knowledge needed. All it takes is a little time and concentration and you'll be able to recover all of the important data on your SD card.
Locate the read-only lock on the SD card. It is located on the side of the card near the bottom, just above the gold connector teeth. If your SD card is cracked, then the cover of this lock will have broken off, revealing a small gap. It is this gap that needs fixing.
Cut a paper clip to size with pliers. Cut the paper clip so it is the exact same size as the plastic lock that broke off your SD card.
Dab the ends of the paper clip with industrial glue. Use only a drop of glue. Adding too much could result in dried clumps of glue on your SD card that prevent it from fitting into the appropriate slot in an electronic device.
Insert the paper clip in the gap on your SD card where the plastic lock used to be. Fit the paper clip so it is flush against the side of the SD card.
Wait for the glue to dry completely, then insert your SD card into an electronic device and test it. At this point it should work without any problems.
