How to Unwrite a Protected SD Card

SD cards are commonly used in cameras and MP3 devices to store information and files. They also can be used to transfer the data to your computer or another device. SD cards can be write protected so that unauthorised users cannot modify or delete files. The write protection on an SD card can be activated accidentally. After you remove the write protection from your SD card, you can then delete and modify any files that you could not access before.

Remove the SD card from the digital device or computer.

Look on the side or bottom of the SD card for a switch. Either the switch will have a picture of a lock, or it will have the word "Lock."

Slide the switch to the unlocked position.

Insert the card into your card reader or device. You can now write information to the SD card.
