How to Fix SD Card Encryption Error on Android?

Case 1:

When my Android phone is encrypting the SD card, I receive a message “SD card encryption error occurred” on my Android device. If I click on the error, it will take me back to the “Encrypt external SD card” screen, which falls into an infinite loop. Therefore, I can’t see any files (mainly photos and videos) on the SD card. If I put the SD card in my laptop then the files will be visible, but if I try to open the file, it will show that they are too large or corrupted. – Monica

Solution: Hi Manica. Creating a copy of a file from an encrypted SD card can only be done by a device with an encryption key. You cannot retrieve files because your phone cannot read the SD card correctly at this time. If you are lucky and the reason for the error is simply that the SD card file system is corrupted, then you can fix it with the Windows Check Disk command. If you want to know how to run Windows Check Disk on an SD card, use Google as a guide. Keep in mind that if the current file system on the SD card is not corrupted, there may be other reasons for the error.

Case 2:

When I needed to access work emails on my Android device, my problem started. Through the MDM (Mobile Device Management) policy, I was asked to encrypt my mobile device and my SD card. When I format the SD card, I can add music and other files. But when I have to turn off the phone to remove/replace my battery and then restart the phone, I can continue, but my SD card is not encrypted at startup. At the meantime, my Android phone received a message “SD card encryption error occurred”. When I encrypt the device again, it says “Unable to encrypt the SD card”. – Sam

Solution: Hello Sam. You can try turning off your phone, removing the SD card from your phone, plugging it into an adapter and putting it into a laptop running Ubuntu (Linux). Propose an xterm, determine the path to the card (basically by installing and then uninstalling it), then run fsck.vfat / <path-to-SD-card>. After that, put the SD card back in your phone to see if this error still shows up. Note that you can do this by running Check Disk under Windows or by running some equivalent functions on your Mac. Please note that only files are encrypted; the file system is not. If it is a file system error that causes the SD card not to work, you can fix it.
