- This Sd Card Cannot Be Decrypted Because It Was Encrypted On Another Device
- Sd Card Encryption Windows 10
I confused and try everything that I know but FAIL ! I have 32GB sd card, I want to format it. I don't care with the data, I want to use the memory card only. I'll tell the the story first:
I wanna encrypt my sd card in my tablet android, I encrypt it in settings and encrypt external drive. I wait in some hours but when encrypting finished, pop up tell the encrypt is error. Then I decrypt it and success. I then use it but failed. I unmount and inserting again but the system tell I must decrypt again (I have try but this loop loop again).
'SD card encryption is turned off. Turn on SD card encryption by tppig Turn on below. To use the SD card, tap continue to decrypt or tap turn on to turn on SD card encryption'
I have tap Continue and success decrypt but If inserting again, its look again.
I have try such us :
- format using windows [didn't working]
- format using software sd card formatter 4 (https://www.sdcard.org/downloads/formatter_4/) [didn't working]
- wipe use disk wiper (erased option) [didn't working]
- use diskpart and clean all [didn't working] -> error occured
- deleting using ubuntu [didn't working]
- format use another phone and camera [didn't working]
Anyone could help me please? I just want to use my sdcard, I don't care with the data. Any help is appreciate
nb: I already factory reset my phone and formatting using my phone, but data still there not successed to format.

Diskpart
This will take a long time (about an hour per 16 gigabytes)
- Launch Command Prompt (Windows+R, type in '
cmd
' and press Enter) - Issue the '
diskpart
' command (this will launch thediskpart
program and you will get a user account control notification, just hit 'Yes') - Once you're in
diskpart
, run the command 'list disk
'. A list will appear. Find the device you want to format. - Issue the '
select disk 1
' command but replace '1' with whatever device it was on the list - Issue a '
clean all
' command - Once it's done, go into 'Control PanelSystem and SecurityAdministrative Tools', double-click 'Computer Management', then click on 'Disk Management'. Right-click on the device you're formatting and click 'New Simple Volume'. Choose 'FAT32'. Pick a drive letter and then click 'Format'. Wait a few seconds and then click Finish.

My wife had a Samsung Galaxy S3 which she just traded in for a new phone. I would like to get some of the files off of the micro SD card if possible but it was encrypted.
I have tried using cryptsetup on my Linux machine, hoping that this answer would work, but it doesn't appear to be a LUKS device.
In hopes that it would help provide some kind of path forward, I took a hex dump of several files of different types. Here are the first ten lines of the dumps from a few of them:
This Sd Card Cannot Be Decrypted Because It Was Encrypted On Another Device

There are definitely some similarities, for example:
- They start with 5 null bytes
- The string 'b._CONSOLE' (and the following bytes, up to the nulls) appears in all of them, followed by a large number of null bytes
- The null bytes go on much longer than these lines would suggest
I'm hoping this will help trigger someone's knowledge of how this encryption might work. I can't find anything about what this format might be. We still have the SD card but I'm slightly worried we might need the phone to decrypt the files.
Any suggestions on how we can access these files?

I know the OP is probably moved on from this, but I may have made some progress on this, but not all the way solved.
First of all, my card was formatted in exfat, so I needed to install that [apt-get install exfat-fuse]
Next, I couldn't get the Luks decryption to work, but through trial and error I found that it works with the plain type..
sudo unmount /media/user/sdb1
sudo cryptsetup --type plain /dev/sdb1 sdcard
At this point you enter your password and it decrypts the filesystem (or seems to).
The last step should be mounting the filesystem this creates, but I run into an error when I put in:
Jurnal teknologi pangan. sudo mount /mnt/mapper/sdcard /media/user/sdcard
It requires to know the filesystem, and I have tried entering every type of filesystem, but cannot get the mapped filesystem to mount. So frustrating because it just feels like I'm on the cusp of solving it.

I have a Samsung Galaxy S5 duos with stock Android Marshmallow, and I'm considering encrypting my SD card to prevent access to its contents in case I lose my phone. The main reason of not doing this is that I'm not sure if there's a way to mount an encrypted SD card on Windows (or other desktop OS's)
When I encrypt the SD card on my Samsung Galaxy S5, is it using a known implementation of encryption, or is it something that only works on Android (or perhaps Samsung) phones?
I do not want to use USB connection to my phone to access my SD card, it's terrible. Mounting the SD card is much easier and faster and less annoying.
EDIT: just to clarify, I am NOT talking about adoptable storage. I want a portable encrypted SD card that can both be read on PCs and Android phones (i.e. I want to be able to remove the SD card from my phone, plug it into my PC, provide a password to decrypt and read/write it like any other SD card)

Marshmallow has two ways to treat the external SD card : Drivers samsung np-rv410 ad2br windows 7 download.
- Portable Storage : In this the entire memory of the ext.SD card is available for use, if it is not encrypted (natively) and you can mount it on your PC to read/ transfer contents
- Adoptable-storage: In this the ext. SD is treated as a part of the phone and when you encrypt the phone, the ext. SD card is also encrypted. Once it is encrypted, it can only be read through USB and cannot be read independently by using a card reader to mount on your PC. You can read more on this at adoptable-storage tag and it's wiki has questions to answer the common concerns. So, for all practical purposes encrypted ext. SD card cannot be read on PC independent the device. However, if your device is rooted, you can try the method suggested here How to decrypt Adopted Storage?
- Full Disk Encryption details different encryption modes on Android Marshmallow. Whether OEMs implement it with additional security features is not known and surely won't be shared on public domain
Edit: Answering OPs query in comments and edit to question
See How does Samsung implement SD card encryption?
- Samsung implements proprietary encryption as evident from the question and also this Reasons for full disk encryption differences between Nexus & Samsung
- Encrypted card cannot be read without the device as on the first question linked
So, it would be not possible to read the card on your PC, by mounting it via card reader on your PC as you propose to do. To clarify further, it can be read if you connect your device using USB
Edit: For a technical understanding, see the excellent answer here How does Marshmallow encryption work technically?

The encrypted SD card cannot be accessed in a PC unless you are connecting via a USB cable with the parent phone.
Android Marshmallow (6.0+) have a unique feature to format SD card as internal storage (I think this carries some encryption along with the formatting process). I have tried this, and after it is formatted to internal storage, the SD card is useless without mounting in the same phone in which it was formatted.(Edit: Unless you have root access.)
However SD card can be accessed from a PC, after formatting the SD card.
