SOLUTION 1 - Unlock the memory card

If you are using a microSD to SD adapter, make sure the Lock switch on the left side of the adapter card is slid up (unlock position).

You will NOT be able to modify or delete the contents on the memory card if it is locked.

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 SanDisk support to check warranty status.



SOLUTION 3 - Check the mobile device settings
Some mobile devices have a feature to lock the card.  Please check with your mobile device manufacturer for instructions to unlock it.

NOTE: If the above steps do NOT resolve the problem or if the lock switch is missing or broken, please back up your data and request a replacement using our online web form.
