Look on the top right of the memory card for a little tab on the side. You might even see the word "Lock" with an arrow pointing down. Push the switch up toward the end that has the metal contacts on the back. The card is unlocked, but sometimes it still might not work properly.
Most SD memory cards integrate a locking feature that allows the user to write-protect the card with just a flip of a switch. This is handy when you have important data, such as photos or music, on a disk that you don't want accidentally deleted. This is reminiscent of older floppy disks that had similar features. You can unlock the card by flipping the switch or disable it permanently with a little tape.
Things You'll Need
- Black electrical tape
Slide the locking tab up and down three times, and then leave it in locked (down) position for 30 seconds. Push it back up to the unlocked position, and use the card again.
Cut a small strip of black electrical tape approximately 1/4-inch wide and 1/2-inch long. Push the locking tab up into the unlocked position and wrap securely with the tape. This will prevent the tab from accidentally sliding back down to the locked position. This technique will also unlock a card whose tab has been removed. If you ever need to lock the tab again, you can simply pull off the tape and slide the tab down.
