How do I disable memory card encryption?
To disable Memory Cards encryption, you must first decrypt the data stored on the card using the device or account that was used to enable encryption. Then you need to disable the encryption function in the settings of the operating system (e.g. Android, Windows) and in some cases also format the card.
What is memory card encryption?
Encryption involves securing the data stored on the card in such a way that without the correct key (i.e. password, PIN or account details) the files become unusable. This is used e.g. on phones, tablets and laptops to protect the user's privacy if the device is lost or stolen.
How can you tell if a memory card is encrypted?
An encrypted Memory Cards can only be read on the device that was used to encrypt it. If you try to open such a card on another device, an error message or information about a corrupted medium may appear. The data on it will look random or empty, even if it physically occupies space.
How do I disable Memory Cards encryption?
If the card has been encrypted e.g. on an Android phone, you need to put it back into that phone, unlock the device and go to Settings → Security → Encryption and credentials. There you should see the option "Decrypt SD card". Once this is selected, the system will start the decryption process. This can take several minutes and should not be interrupted, as interrupting the operation risks losing data. Only after full decryption can the card be removed and used in other devices. In some cases it may also be necessary to manually format the card, if the data is to be completely Deleted or if the card is to operate in a file system compatible with other hardware (e.g. FAT32, exFAT).
What if you no longer have access to the device?
If encryption was associated with a specific device or account (e.g. a phone with screen lock enabled) and you no longer have access to it, you will not be able to decrypt the data. This is a deliberate security feature. If this is the case, the only way to continue using the card may be to fully format it, which will remove the encryption but also permanently erase all files stored on the card. If in doubt, especially when working with corporate data or important documents, it is worth consulting an IT specialist or technical service.
