Hi all
Samsung S7, standard rom, encrypted SD card (Samsung 128 EVO)
My 128GB SD card held a huge amount of photos amongst other things. One day, the card stopped mounting (and I therefore couldn't decrypt the files). Taking the card out and putting it in a card reader connected to the phone, it would mount but didn't give me the option to decrypt the files. I copied all the encrypted files to my laptop, and formatted the card. A different volume name was generated. I copied all of the files back to the card, but the data couldn't be read. I imagine a new key was generated when I re-formatted the card.
Data recovery tools can see the files, but they remain encrypted.
Renaming the volume label to the original name and trying again didn't work either.
I have not changed my pattern code, not done a factory reset, and have not updated the OS since.
How do I go about recovering the encrypted data. I have all the files, but no way to decrypt them using the phone. Is there any way to restore the files?
You can try this
I am very hesitant to overwrite back all the encrypted files to the SD card so as not to write over the old files (which I can see in a data recovery tool, although they are encrypted)
So, I will try the following.:
1. I will connect an old SSD and format it as external storage and encrypt it using the method you linked.
2. I will copy the 80GB of encrypted data backed up on my PC onto the SSD (probably using wifi)
3. I will then try decrypting the external SSD drive using my phone and see whether I can read the files
4. I will report back
Ideally, I would like the volume to have the same volume name as the original SD card volume. I wonder if this plays a part in the encryption/decryption process
If any other suggestions are forthcoming, I'll take them too!

My work requires encryption of the SD Card. After doing a factory reset, Android reports unable to mount SD card and to format.
Using twrp, i can view the file structure when i mount the sd. I cannot view the data partition because the device is encrypted.
Using my PC, i can view the file structure, but when i try to open a pic or zip file, it says the file is unreadable/corrupt. I would think that it if were truly encrypted, i would be able to view the file structure.
I can even take a nand backup and save it to the SD card, so i know twrp can read/write
I plan to format the card, but since i can see the files in twrp, i just want to make sure i am not missing something. Or, get an OTG cable and see if i can copy files off SD Card to a thumb drive...
Hi Guys, yesterday i decided to reset my xperia z5 to factory defaults because i wanted to have it with the apps i use the most and remove all of the others that i didn't use that much. So instead of uninstalling the ones i didn't use, as i said before, i did a factory reset. Before doing this i decided that it would be nice to take out my sd card to copy some pictures, without remembering that i had my sd card encrypted with my fingerprint, so i did the factory reset (with the sd card out of my phone) and after that i noticed that there was a marshmallow update for my phone, i accepted the update (with the sd card off my phone) therefore when i moved all the sd files to my NAS and i put the sd card back in i saw that all the files that i had moved to my NAS where still there. after that i decided to format the sd card with my surprise of seeing a Windows error message of "windows cannot complete format", i did a low level format, formatted my sd card with disk part, etc. None of the things i did worked, Do you guys know what i could do to my sd card to delete all the files in it?
Thanks a lot
I wiped my phone (Priv) when I sent it off for repair. I was using the SD card as internal storage (Android 6.01). I just got the (same) phone back, set it up, then put the memory card in, and it is telling me I need to format it before I can use it.
When I look at it's contents with a reader in windows, i can see a directory structure, but it won't let me copy any files off it. I am guess this is to do with the encryption.
Is there anything I can do to recover the data on the card? I had assumed when I signed in again with my google account, all would be well again!
I'm getting a new microSD card for my SHIELD Tablet. The card I have inside currently is being used as adoptable storage. I want to transfer everything from that card to a new one I'm getting. Is there a simple way to backup everything and just have it auto reinstall or something like this? I don't want to have manually reinstall everything if I don't have to. Also i am not rooted.
Someone mentioned something about cloning SD cards for a raspberry pi, so would this potentially work for a micro SD card?

if anyone could provide assistance, that would be helpful
I don"t think you can clone adopted sd card. It has two partitions: 1st 16mb(infos, fat32), 2nd rest gb, ext4, encrypted. New sd card has another name & s.n., it will be not recognized.
You can move all apks you can to internal memory, rest of data copy to PC. You can use google backup too.
Set old card as public, eject it and insert new. Set it as adopted and copy data back from PC.
I think you can loose something from the folder /Android.
Without root & twrp backup&restore everything is impossible. @toph the earthbdner
My SD card is set as adoptable storage, but it has gotten corrupted. It happened when I was copying files from my phone to PC via USB (ironically I was doing this to backup my files from my phone). Somewhere during copying, the phone virtually disconnected from the PC, and on my phone it said that it couldn't read my SD card.
Couple of things to note:
I'm using Lineage OS.
The SD card isn't encrypted.
When connecting the SD card directly to my PC, the SD card shows as two drives, D: and E:, with D: being accessible showing an almost empty drive of 29,4 GB (which is the full logical capacity of this drive), and E: inaccessible, requiring a reformat (no idea what E: is). On D: the folders that I can see are .android_secure, Android (with the sub folders data and media) and LOST.DIR. All folders are empty.
This SD card should be filled with data almost up to max capacity.
I haven't changed a thing to the corrupted SD card. I did not reformat, used CHKDSK or w/e. The only things that I have done is attempting to make raw copies with HDD Raw Copy Tool and R-Studio.
I've read here and there that it is (almost?) impossible to logically fix a corrupted adoptable storage SD card in that I could just pop it back into my phone to resume where I exactly left off. So I'm looking to recover as much data from the SD card as possible. I'm most concerned about recovering my Whatsapp folder (I haven't got a complete GDrive backup of this), but I'd prefer to recover everything else as well.
What must I do?
