How does moving the little switch on the side of an SD card write protect it when accessing it from a computer?
In: Technology
On SD cards it’s just a software thing. The card reader doesn’t have any mechanical ‘feeler’ or anything. Inside the card there’s some circuit thingy that gets switched and it’s super tiny and fragile which is why they break so easily.
Btw there are devices that refuse to work with a card on which write protection is enabled.
