I want to encrypt my SD card but when I tell it to apply encryption and encrypt the card it unmounts the card and I get the error "Error encrypting SD card. Unable to mount SD card" then my device will not recognize the SD card until I go back through SD card encryption and tell it to disable encryption. Thoughts?
Hello,
I use a 128 GB SD Card in my new S7 Edge, but I can't find a way to encrypt the SD Card.
I don't want someone have access to the data on the card if my phone gets lost or stolen.
Thanks for helping

Settings -> search "encrypt" -> Encrypt SD Card
Thanks! I was only looking under "storage"...my bad.
Hello,
I see in security options one for put a password to SD Card, but it does not encrypt the SD. Also I have seen in internet it is very easy for a thief to get the password in a PC. Do you know if is there any way to encrypt the sd card? also is internal memory encrypted?
thanks.
My phone's screen is dying and I cannot view anything from the display.
I want to transfer everything in my SD card to my new phone but unfortunately the SD card has been decrypted.
Is there any solution to decrypt my SD card without the phone screen?
I think you can't.
Hello,
I've add a 256GB SD card on my Fire HD 10, and I set it as portable storage.
My SD card is a Sandisk micro SDXC UHS-I (V30 3U A2).
All time I logon on my Fire HD, FireOS shows me the settings page "How you will use this storage device".
Is it a known FireOS bug?
Or, do you think my SD card is defective?
SD card in Portable storage mode comes with data robed risk if I lost my Fire HD.
Thus I'd like to encrypt SD card data.
FireOS offer Encryption feature in settings.
Does someone have experience with it?
If I set this SC card as "tablet storage", does data will be able to be readable from another device?
Thanks a lot for your help and advices
Chris
If the SD card is not properly formatted as FAT32 or exFAT (or wrong alignment) Android will offer to format.
If you format as portable storage the SD card is not encrypted (recommended). If you remove the SD Card you can read it on card reader on PC later.
If you format as adoptable storage the SD card becomes encrypted and will replace the internal storage (which becomes unused). This is not recommended as the encryption key is inaccessible to nobody, therefore no way to recover data in case of failure.
Thank you alecxs.

In this case, all data on SD card will be readable by anyone if I lost my pad.
Is there a way to encrypt data on a SD card formated as portable storage?

I think the only way to do what you're after is with a 3rd party tool to encrypt your SD card. I suppose that's possible, but performance may be sluggish that way.
if you downgrade to Fire OS 5.6.4.0 you can use mtk-su to access the encryption key from /data/misc/vold once. this key can be used on linux PC to decrypt adoptable storage (except for FBE file-based encryption)
How to decrypt and split adopted storage?
How to partition and to have adopted storage at same time. You don't need to root your device but the device i done this with is rooted You need to enabled Developer Options. Enable the USB Debugging option. Make sure your SD card is formatted...

(obviously) all other 3rd party solutions require similar additional software to decrypt container stored on portable storage.
Transparent Folder Encryption
Greetings, I'm looking for an App that would provide transparent folder encryption, along the lines of the "Encrypt contents to secure data" option on a Windows folder. One that works on a SD card, and also treats files transfers via USB cable...
