How does moving the little switch on the side of an SD card write protect it when accessing it from a computer?
In: Technology
~~The tiny slide switch is connected to the tiny computer inside the SD card. If the switch is flipped, the controller disregards write commands coming from the host device.~~
The plastic bit depresses a small switch in the reader or not, depending on its position. Apparently it’s up to the reader/operating system to actually respect that request for read-only operation.
