How to Turn Off Write Protection on an SD Card

The secure digital card is one of the most ideal methods of transferring data from one device--such as a cell phone--to another, such as your computer. It is the modern equivalent of the floppy disk. Many programs come on SD cards--even some movies. To add data to a card, it must be free of write protection; once your card is unprotected, add or delete data at will.

...
Secure digital cards are portable and convenient.

Step

Grasp the SD card with the gold contact points facing you.

...
Make sure the gold contact points are clean.
...
This SD card is write protected.

Step

Note the position of the tiny white write-protection tab on the right-hand side. The write protection is turned on if the tab is close to the contact points.

...
This SD card is not write protected.

Step

Slide the tab away from the contact points in order to turn off write protection.

...
The notch is on the right-hand side and the tab is on the left.

Step

Turn off write protection by placing a piece of cellophane tape across the notch if sliding the tab doesn't work. Be very careful to only tape the notch and not the contact points. If the tab is broken or missing, place a piece of cellophane tape across the opening where the tab should be.

Step

Remove all tape to protect your data again.
