Locked out of encrypted files - Samsung Galaxy S7 Edge Questions and Answers

So I bought the S7 edge popped in my SD card and encrypted It. The card was giving me some issues so I backed up my files on my Pc formated the SD card and reloaded the files (MP3s) now when I go to play many of the songs they don't play and just say "sorry unable to play file type" it's odd because about half of the songs do work any ideas for fixing this I have a quite a large music collection and it would be quite pain staking to have to download these one by one again

Would encrypting them and decrypting them help?

Really none of the brilliant minds here at Xda have any idea?

Did you copy the files off with the SD in a pc reader or via mtp from the phone? I would guess the the base encryption key data is different since you reformatted the card, it would make sense to me because otherwise there would be no point to supporting SD encryption.

If Google did their work well, not likely.
I don't know the details but the only consumer hope would be with the card inserted in the device that formatted it as theoretically the encryption of the SD card should be done with private key data that is tied to the device it was formatted within (in addition to whatever private data you provided such as a PIN). Otherwise it would be too easy to just move the card to another device to decrypt the data.
I've seen some references to the Android SD card encryption *not* necessarily encrypting media files (music, movies, pictures?) so it's possible those files were not at all encrypted - which is substantiated by the fact that you can play SOME of them.
It may be that the files that don't play are, unfortunately, simply, corrupted data and not encrypted at all. ;^(

I had the exact problem, it seems to be some issue with a lot of S7's from from my research online. After almost giving up after a few weeks I finally did find a fix which hopefully will work for you and anyone else who has encountered/ will encounter this problem. Here are the steps I took:
1. After the sd card became unresponsive on my phone after encryption, I transferred all my files from the sd card to my PC. I had to do this via the sd card slot on my laptop as the card was not being recognized when connected via the phone.
2. I then formatted the sd card on my PC. For those not familiar with the process just right click on the card in "my computer" and select format then quick format.
3. I then reinserted the card into the phone to make sure it was recognized, then removed it again, inserted it into the PC and transferred all the files back over.
4. I went into my phone under security settings and changed lock screen security to "none" while leaving fingerprint on.
5. I put the sd card back into the phone with the files. They won't be accessible as yet since they're encrypted but the next step is to go ahead and encrypt the sd card. Wait however long you have to, for me it took less than a min. After this go back and decrypt the sd card, let that process run through then the files should now be decrypted and accessible. If the sd card goes unresponsive again just try again by formatting the sd card and putting the files back, this time maybe a few files at a time.
If this method works for you I would suggest backing up your data frequently and staying away from encrypting the sd card at least until samsung/android release a fix for this issue.

My micro sd became unusable after encryption.

I have enabled the Encryption on my PDA and then I have disable it, I couldn't save anything on my micro sd card and I hard reset my PDA. I have backed up my files and try to delete them from sd card and nothing happened. I have connected the micro sd through a card reader on my PC and I tried to format it and I get a message that cannot perform format. I have deleted the files manually from PC and when I connect the card back to device I can see all files on the card as was before.
Can anyone help me format the sd card and use it again from the beginning?
The encryption in WM6 really sucks. It encrypts the files and makes .menc files of them. The problem is that there is no option to store the encryption key, so the files are only usable on the phone that encrypted them. If you want to view the files on another phone or a pc you can't. the same if you put another rom on your phone.
To format the card i used wm5torage and connected the phone as an removable device. Then you can format the card from your pc. There are also various maintenance programs for WM that can use to format the card.
At last there is a manufacturer from sd cards where you can download a low level format program (cant find the program anymore in my ever growing download folder, so can't be more helpfull )

yup it really does suck.... happened to me once... what i did was (which resolved the problem)... removed the check on the radio button, then added new files to the sd after the encryption is disabled. all my files are back to normal. you shouldnt have formatted your device as the encryption keys will be lost as well...
you can also try pocket mechanic to reformat your card...

Using SD card from Rezound in the S5

Sorry guys, I am traveling right now and my wife needs a bit of help.
She took her SD card out of her Rezound and put it in the S5. She is trying to figure out where everything is stored as when you look at the SD card (when its plugged into the PC) its not showing all of her files?
Basically she needs to move music over and when the SD card is in she cant find anything on the phone. Is there a new format that needs to be used or does anyone know why she wouldnt be able to view the entire contents of her SD card while the S5 is plugged into the PC?
bump... I am having this exact same issue.

KitKat changed how apps can access the external SD card so if you just swap a card into a KK device you will probably not be able to access all existing app files with same apps you had on the old device. When you plug it in to the PC however I'd expect that you can see everything (unless some files are hidden for some reason). So maybe her music was on the 16GB internal storage of the Rezound?
File transfer is fast on USB 3.0 so just format the card through the new phone (Settings> Storage> Format SD card) and transfer it back over. I usually create a "Music" folder in the root of the SD card and dump whatever right in when it connected to PC... I just did this on my S5 a few minutes ago and the phone saw the music when I started the Music app.
I'd consider it good practice to format the card when changing phones anyway.

Disappearing files in MicroSD Card.

Greetings,
I transferred my Pictures and music from my old SanDisk ultra 64GB micro SD card to my new Samsung Ultra + 128GB card. My first attempt at loading the data was through the restore function on the LG Bridge app from my PC. 3 day later when the restore was finished the phone indicated that the data was corrupted and had to be formatted. The second time I got a "file Corruption" message on my SD card when I was transferring files while both cards were in card readers. The next attempt was with the old card in the card reader, and the new card in the device, with the device connected to my laptop directly by USB, the end result being the Corrupted file message (again). My most recent attempt is by downloading files from my PC to my device card. Now the files are gone when I restart the device. The Music file in my folders are gone but the music outside of the folders are still present. All my pictures on my card are gone as well. ANY help is desperately needed and appreciated!!!
Did anyone have an answer to this? I'm having the same issue with my V30 - the files I copy to the external SD card by any means (AFT, SyncMate, FTP, SyncTunesMac) disappear...
I don't have good news for either of you that sounds like the sd card or the card port are going bad. Is it possible your ad cards are counterfeit as in does this behavior happen with another known good card...
I would try the following
First backup anything you can
Try a known good card that works in other devices and see if the behavior persists if yes
It is an issue with the phone not the card if the behavior stops you both got bum cards be more careful where you buy amazon is not even safe.
If the behavior persists try resetting the phone full factory. If custom Rom reload the rom. If the issue persists past that you most likely have a hardware issue that requires mainboard replacement.
Also try uploading files to the cards using the computer(with the micro sd to sd adapter) and check if the files stay(using the phone)
I had a similar issue with Moto G Turbo with Lollipop. It permanently damaged 2 MicroSD.
I ended doing a factory reset and MicroSD worked correctly again.

By the above description, this is almost certainly a counterfeit sd card.
Google "H2TestW_1.4.zip" to test ANY card you buy before you ever use it.
It's a solid, lightweight program that does its job well.
Anything that says it will do the job better / faster is blowing smoke up your skirt.

No Access to SD Card Please Help

16gb isnt enough, bought a 64gb sandisk sd card but after inserting it in and setting up as portable storage, my phone cant write files to it??? I have to use a special browser with root access just to delete some pics. On my old phones it had a directory name like "sdcard1" but on this it has "9DAE-180F". Its recognizing it like a otg usb drive. Which i think is my mistake cuz i chose "setup as portable storage"
Now i have a lot of data on my sd card which would be a pain in the ass to backup and then retry formatting as internal storage. So what i wanna know is will it have proper sd card access for all normal apps and behave like a normal sd card like all other phones i ever used? Or am i just gonna waste time trying out all this.and formatting wouldnt work?

I believe in MM and above we have to explicitly allow apps to access the external storage. check your gallery/photo app permissions and see if access to 'storage' is enabled
Update: i backed up all the data and when i formatted the card as an internal storage it extends the internal storage. Which solved the issue . But when i remove the sd card and connect it seperately some files show up and some dont. U dont know if the files is weather stored in internal or external storage which i dont care about anyways cuz im never getting the sd card out of the phone again. Lovin it

android will encrypt the sd card if you set it as internal storage and you won't be able to access the content outside the phone, so if your phone goes crazy or bricked, there's high chance that you'll lose your files forever

Tablet no longer recognizes SD card after October 2022 software update

My tablet kept bugging me to install the latest update, so I let it do so. After restarting, it no longer recognizes my 200 gb SD card. My computer has no trouble reading the card (it's backing everything up from it now). The card had been functioning just fine until the update. I put in a 128 gb (previously used) sd card I had around, and it didn't read it either. I then fed it a brand new (64gb) card, and it apparently formatted it and recognized it. Has Samsung changed the required file format for SD cards? It seems to want me to reformat my card (hence my backing it up first). Any other options? Of course, the info presented before the update said nothing about causing SD card issues
I dont know man.
I backed up the card, allowed the tablet to reformat it, and recopied everything by inserting the card into the pc. After the recopying it didn't recognize it again. AARGH! So I let it reformat it again, and am now copying just the essential stuff with the card in the tablet and the tablet connected via usb. Windows is telling me this will take 9 hours just to copy one folder with 6gb and 7k (smallish) files. I hope Windows is lying about the 9 hours! There was originally a folder .android _secure. I wondering if copying that over the first time is what prevented the tablet from recognizing the card. So that's not being copied over this time. There's another ginormous folder with about 100gb of largish files. But given the app they go with will probably insist on redownloading them anyway, I may leave them off.
I found there is a statement about the Micro Sd Card in the latest user-book (for Android 13). It says, the system support the format of exFat and Fat, but when you slot the sd card of different format to your device, the system will require a reformat to use it, or your device will not identify the sd card. You can check it on the Samsung website, for the edition I read is Chinese.
