How to Remove the Write Protection on an SD Card From an HP Laptop

The SD card that you use for your camera or MP3 player comes with a security feature called \"write protection\" that prevents anyone from making changes to the data on the card. While write protection can be useful if other people have access to your card, it is also easy to accidentally turn it on when you didn't mean to. Some virus programs can also change a setting on your HP laptop to automatically enable write protection without your permission. You can use the built-in features of your HP laptop to remove the write protection feature from the SD card.
