We use SD cards for all sorts of devices these days, but the little lock mechanisms on the sides can break so darn easily. Here's how to fix an SD card with a broken switch, using nothing but a bit of tape.
Whether the switch on your SD card has completely broken off or whether it's just flimsy (mine locks itself every time I put it into a slot), it can render a card pretty much useless by making it unwritable. Just like the VCR tapes of yore, however, you can buck the system with a bit of Scotch tape. Just stick it over the switch, and it will trick the reader into thinking the SD card is unlocked. Check out the video above for a demonstration, and let us know in the comments if you've been able to salvage any old SD cards this way. Video by cnwaddell.
