Secure Digital Memory card is write protected or locked

Why do I get a "The disk is write-protected" message when I transfer files to my SD memory card?
For SD/SDHC/SDXC memory cards:
SOLUTION 1 - Unlock the memory card.
There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked.
NOTE: If you are using a microSD card with an adapter your issue may be caused by a faulty adapter.  Please try using a different adapter or device that accepts microSD cards without an adapter to verify.
SOLUTION 2 - Toggle the lock switch.
If the lock switch is loose and moves easily It is likely the switch is sliding to the locked position as the card is placed in your host device. In this case the card will need to be replaced. Please contact Centon Customer Care for warranty inquiry.
