Memory card is write protected or locked

Why do I get a "The disk is write-protected" message when I transfer files to my memory card?

For SD/SDHC 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/microSDHC card or a miniSD/miniSDHC card, insert the card into the microSD/miniSD adapter. The SD adapters will also have a lock switch.


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 - Try to Format the card using Disk Manager (For all memory cards)

The data on the memory card may be corrupted. Format the card under Disk Management and then try to transfer files to the device once more.

WARNING: Formatting will delete all the files in the device. Backup all your data before formatting.

NOTE:  If the above steps do not resolve the problem or If the lock switch is missing or broken, please contact SanDisk Support.
