Hi,
beacuase I had no other problems, I thought it would be a good Idea to encrypt my Android device. I did this first for the device through the settings menue and everything went as expected and my device was encrypted after a few minutes.
After that I wanted to encrypt the external SDcard aswell. But unfortunately when I select Encrypt SDcard in the settings menue, and the current password is requested, after entering the password, I get the error message: Error encrypting the sd card. Unable to mount the SD card.Tap mount to mount the sd card, after which the password prompt comes again.
WHen I look in the files directory, the external sdcard does not showup at all.
Anyone knows what the problem is?
I'm using the current STock Rom for Open German devices that was installed OTA a few weeks back. I have only rooted the device and done nothing else to it.
WHat went wrong? How can I get access to my external sd card back?
WHy does google offer such a option if at the end you end up loosing access to your sd crad?

Can you open de SD card on a PC? What do you see?
I don't think that Google intentionally implemented a "destroy SD Card" function. But it could be that something is flawed. It happens.
I can access the sd card on my pc without any error via the mini to maxi SD card adapter that came with the SGS2. I backed up all my files and everything looks normal on the sd card. So i could now format the entire sd card if that is necessary.
Thats the error message i receive:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After clicking continue and entering the password, it keeps coming back to this error message.
I also realized that there is a message showing "preparing sd card checking for errors"
But that never ends.
I formatted the sd card on my pc with different file sizes and with the sdformat tool from sdcard.org, as instructed in many posts that deal with this issue. But nothing helped.
The sd card is however accessible from the recovery menue.
I now removed the encryption from the device via the option in the settings menue. The encryption from the device is now apparently gone, but the message "preparing sd card checking for errors" is still there and I cstill can't access my sdcard.
Furthermore this sdcard has never been used in any other device. The problems started, when I encrypted the device. The sdcard was inside the device when I encrypted it.
I don't know what else I can do. I wish I never had tested the encryption feature.
A solution that worked for me
So this happened with me too.
It went away after I took these steps, in sequence:
1. Turned off the device (full power off)
2. Turned it back on
3. At this stage, the problem persisted
4. Removed the SD Card out
5. I saw the message "It is now safe to remove the SDcard". After I removed it. Oh well.
6. Re-inserted the SD card.
7. The same message came back - but this time it was gone after a few seconds, and got replaced with "the device has been encrypted".
I do not know if it was the entire set, or if it was only steps 4-7 that made it work - I'm just happy it worked

That didn't help for me.
I finally had to factory reset my device and then I first encrypted the SD card and then the device and that worked. Now both my SD card and device are encrypted.
BTW: I restored most of my apps and settings with the app "App Extractor" from my Clockworkmod backups. And that really works.
Only thing that didn't work was restoring all known W-Lan networks from App Extractor.
Things you might have to consider and I only found out later is:
1. You can not update over the air to a newer Firmware version if the device is encrypted. You have to decrypt it first, which takes some time to do.
2. YOu can not make Clockworkmod backups, once your device is encrypted. SO you have to decrypt the device first before you can update to the new firmware or if you want to make clockwork mod backups.
Once you are happy with your system settings, then It is ok to encrypt I think.
I have to add other disadvantages of the ENcryption Option which I just discovered.
1. The external SD card appears not to be encrypted at all. At least it is possible to access the files without any password prompt from the recovery menue. I was under the impression that that would not be possible.
2. If there is not enough space left on the encrypted SD card, a mounting and decryption is not possible anymore!!!!! You need to have at least 14 MB space left for the device to mount a encrypted sd card. If not, then you will not be able to mount it. Also If you want to decrypt the sd card once you have encrypted it, you need at least 400 to 500 MB of free storage on the device.
If you don't know this and have less than this amount of space left, then you will be in trouble and should have a copy of your files from the SD cards available couse formating will be the easiest Option everything else is a Pain in the ass.
I was only able to successfully decrypt and mount my formerly encrypted sd card when I discovered the point under 1.
So please be aware that the Android device encryption schould be considered highly experimental.
I have the same problem

I'm happy I didn't try it now. btw, once card is encrypted, can it b read in a computer ?
The external card never gets encrypted as far as I see it.
I can't remember whether i used the sd card in an adapter on my pc, I assumed that it was encrypted so I didn't try accessing the supposedly encrypted sd card on my pc via an adapter.
but you can access the files from the encrypted device by mounting it via USB cable.
Is google aware of these shortcomings of the device encryption?
They sell it as device encryption and you assume that you are save in case the phone is lost. But that is not the case.
Anyone knows whether these issues have been resolved in Jelly Bean?
Hey,
anyone has tried the device encryption on Jell bean yet?
Are the issues that we have talked about in this post resolved?
Is the external SD now also encrypted or still not?
And is the recovery possible with an encrypted device?
I'm too scared to get in the same problems again and therefore would like to know if someone was already brave enough to try encrypting under Jelly Bean.
OK. I tried encryption on Jelly Bean myself. And the status is unchanged to the prior version. External Card is still not encrypted, despite it beeing show as encrypted in the device settings.
So be aware about that.
Same here
Couple of weeks back, joined the phone to the mail server at work. Was on pattern unlock. SD card said was encrypted and required PIN. What pin? Fortunately, set to PIN unlock and could see SD card contents again. Dumbass that I am, did not immediately back up contents.
Today, went to play some music. No music. No pictures. No video. Tried rebooting phone. No go. Changed PIN. Still no. Reinserted SIM. Nope. Not sure what else can be tried. OI file manager just shows "Scanning" when I try and access the device.
Encryption (this implementation anyway) is buggy and should not be trusted.

Managed to get access again by unmounting the SD card and ejecting and reinserting. It then asked for the PIN (which was the original one, not the new one). Hope this might help someone in the same situation. I'm hoping removing the phone from the mail server and using Divide will work (I'm mostly after calendaring anyway)
Now I'm stuck with the ugly problem that I decrypted the SD card and it is *still* asking me for the password. It's like it is not a full decrypt. I guess the answer is to copy everything off and reformat.
same problem with kitkat
even i have encrypted the device., now i cant use external sd , no option to decrypt. ANDROID sucks :crying:
Any update on encryption for I9100?
Is this a I9100 specific problem or is the encryption buggy for other Android devices as well?
There are several sites promoting the use of Android's encryption feature. Are these guys just not aware that encryption doesn't work? Or does it work for them properly?
I only have a I9100 and can't test it on other devices.
Encrypt SD Note N-7105
I had exactly the same problem and I did many things before to finally solve. I made a soft and hard reset, erase cache-dalvik cache and factory reset annnndddd, NOTHING. Finally I reset it to factory, wipe cache, wipe dalvik cache, format system all what de recovery said that can be resetted except, the modem. I flashed my amazing DN4 v2.2 again anddddd Voilà the "Preparing SD Card for errors" and "Blank SD Card" disappeared. My sd was ok ever. I hope this can help you.

I noticed that under settings > SD card & storage that my Phone storage shows being read only.
I was wondering what may be causing this and if there is a fix for it, because several of my apps no longer work (BeyondPod being the main one I miss) because they need an SD card to work with.
I'm running the out of the box firmware, rooted using amon ra recovery.
I do have an exchange activesync account that requires encryption and pin, not sure if that could be causing any issues.
I did try to search the problem but couldn't find any relevant threads.
do you have SD encryption turned on in settings?
Is that the culprit?
Looks like I need to download that modified Mail.apk
After I re-locked my phone to apply the last GB OTA with new radios, I noticed that when I booted my phone the entire /data partition was in read-only mode somehow and it was causing all sorts of weird problems as you could imagine. Simply rebooting to bootloader and hitting "factory reset" option on the bootloader menu fixed the problem. I was then able to write to /data again and everything was fine. Obviously this will clear it everything. I was then able to apply my nandroid backup though and restore my system to how it was before the OTA.

thats just my guess... turn it off and see if it helps
Started getting weird read errors when trying to read/write to the card while it was mounted in the phone with the password for the encryption already put in.
I think the card was going bad, or just got all FUBAR'd during the encryption process.
Deleted exchange acct, removed SD card encryption, put in new SD card, re-added exchange acct/re-added encryption, everything works!
Awesome newb video by the way! Made me laugh...
Just rooted and I like it, I don't wanna go back, but I can't get the microsd to pick up...I'll give all the info I can--def newb to root/droid but my background is IT, so hopefully we can figure out how to fix it so I can keep the root and not go back to stock(if that would even repair the problem)
Got a pny 32G microSD, droid incredible 4g lte(Verizon) that I rooted using the unlock script and fakeCID and then loaded Vipers Venom LTE custom rom...somewhere in this process-I think right after unlocking-it quit accessing the sd card...I've looked around and read some things about this 'USB brick' thing, but I don't know if it's applicable to me...here's what it does now:
SD card is in phone, but under 'Storage' Total Space and Available show unavailable, and everything else is greyed. If I try and pull the card the phone gives me the 'sd card unexpectedly removed' error.
Windows XP has no issue reading/writing to this card with a card reader. I've formatted a few times fat32 with xp(which i hate doing)and put it back in the phone, with the phone off, booted, and nothing happens. Oddly, when it first happened, after installing the custom ROM, when I'd do this procedure the phone would see the card on boot, but stay forever on 'preparing sd card/checking for errors' and never complete.
Back on the phone side of things, booting into the 'recovery mode', where you flash and whatever, it can see the card, see it's contents, and I wrote some sort of log to the card(option in the menu), so it can access it...oddly, I could not load my Viper rom from the microsd card, it failed on the file, but put it under some folder on the phone and that's how i ended up flashing the ROM, which I was nervous about doing as everything I saw said put the rom on the external sd card...
If I plug the phone into the XP pc via usb cable, choose use as disk drive, no problem accessing phone data, but 'please insert disk' on the card. Cannot push data when in usb debug mode via adb commands either. Oddly, dunno if this is related, it gives me 2 drives and also a CD ROM drive--tried dialing that##7 number for the option to disable cd rom, but it was already disabled. Dunno if this is related, but throwing it in there.
Tried chkdsk on the sd card with Xp, no errors, no problems. Hell, the card's not two weeks old and I've only had the phone a little over a month. I've done a bit of research the past couple of days and the only thing I haven't tried is the very confusing procedure i've seen for some of these 'usb brick' problems, but is that my problem. I'm hoping if all else fails i can go back to stock, just downloaded the stock rom, but will that even fix it? Gots to have my trailer park boys on my sd card to watch! Thanks for the help guys and gals! Sorry for the long post, but I like to give info--if kernel version or any other data like that is required, I can post it.

i tried to slim down your quote, but from my experience i'd still say the sd-card is somehow busted! i had a similar prob with the SD card in my Dinc4G two weeks ago. i _was_ r/w quite fine even from custom rom and at one point, the card just quit. removing and reinserting just ended in "preparing sd-card" and directly after that "safe for removal" ... wasn't able to access it any more within Viper, recovery (TWRP for me) was still seeing the card fine just like on your end.
putting the SD-card into a Win-laptop it _appeared_ fine and came error-free with scandisk etc ... BUT when i tried to backup all data from it before formatting (had like 10G on my 16G card) there were a couple of files that failed to read and i could NOT recover at all anymore. I formatted the SD-card again after that (full format, not fast/quick!) ... and put most of the files back. it is working again now in my Dinc4G but the card sure has some defect sectors (and usually _tends to die soon_ after such errors appear first!
i'd heavily recommend that you try to source some other micro-sd card first and try if you custom rom can read from it again. if that works fine and you see your SD-card from within the settings menu in the rom. you can be pretty sure that it's really the card.
PS: even brand new mem cards tend to fail at times :cyclops: ... just try to erase all private data on it (means: _fully overwrite_ with other stuff until the card is completelly filled) ... and then try to get a replacement from where you got your (fairly new) SD card from.
hope that helps a bit
i agree with the above post... try a different card. if formatting it doesn't fix it, it's time to try a new card.

Thank you for the help, I resolved this issue, as it is the card, but now I have a different issue, unfortunately...
I recently decided to go from Jedi VX13 to ParanoidAndroid. Since I was going to 4.2.2 from 4.1.2 instead of the other direction, I thought that I wouldn't need to take any special precautions to keep my SD card working. The flash from CWM went fine and the phone booted up normally. However, no matter where I searched, the SD card directory was nowhere to be found.
I have read many posts about the card data being in another place, but I have used Root Explorer and Solid Explorer search functions without any luck. I even installed TWRP over CWM and formatted the SD card from there at someone else's suggestion. The phone can see that a card has been placed into the phone, because the Storage menu gives the Mount SD option. However, every time I press it, I see "SD card is blank or has unsupported file system". I have even pressed the offered format option in the 4.2.2 OS multiple times with no luck. I can't believe that the SD card has to have files on it to be mountable by the OS.
The card is readily accessible in TWRP and on my computer, so the card itself is not in error. I have even taken the step of doing a scorched earth wipe of the internal memory to try to solve this. I am missing some crucial step in the formatting or mounting process, but I am out of ideas at this point. Any help that can be offered is appreciated.
Please close thread
After I was finished typing this out, I flashed the newest ParanoidAndroid build. Not only does it stabilize 4G, but my card is now recognized! Please close this thread as soon as possible.
So when I joined my phone to the corporate network, it insisted on (amongst other things), encrypting the SD card. After some annoyance with that, pins etc, I decided to revert back. I successfully removed the accounts etc and unchecked the encrypted SD card option.
However, when I did so, it said something about only applying going forward and I still keep getting asked for the pin to decrypt the SD card. So it seems that stuff is still decrypted on there? I have done some searching but have had little luck finding any definitive answers, most seem to be related to problems with people losing whatever key to decrypt items which is obviously not the case here since once I enter the pin, I can access items with no problem
So what's the deal? Do I have to save everything off and reformat the SD card to get back to normal? Seems kind-of wonky to me but that's Android, I guess.
Oh, I have tried reencrypting and unencrypting the SD card again and the Android version is 4.1.2 if that's any help.
[Solved]
Not sure how to mark this solved. Maybe a mod can do it.
So I ran into some issues with the phone and managed to back up my data, completely reformatted the card and copied all the files back to the SD card.
*Still* I would get the "encryption password" popup. Nothing was encrypted, I could view all the files if I used a card reader. Yet when I plugged it back in, I either had to enter the string or couldn't see the files at all (even though they were clearly unencrypted).
The culprit?
/.sds.bin
I deleted that and everything is fine again. I guess it hung around when I disabled the encryption and was causing my misery. I hope this can help someone else who might be having the same problem
Funnily enough, now that I know what I am looking for, I found the exact solution to my problem here.
https://community.verizonwireless.com/thread/777978?start=0&tstart=0
In fact, there is a hidden and very magic file sitting on the card named ".sds.bin" which is the flag to Android that the data on the card (may) be encrypted. If you remove this file (easiest on Linux or OSX) and then put the card back into your phone, you will be back in business. It seems as if someone at the Google forgot to remove this file when I told it to decrypt my phone earlier this year.

Hi all
I have a Samsung S20 Ultra with a memory card that all of my photos are saved to, unfortunately I had to take my phone into Samsung experience store for a screen / back cover repair, the staff removed my Memory card and told me to factory reset due to GDPR as the device had to be sent away, when my device returned in the post 5 days later I went to put the memory card back in and a notice appeared stating the memory card is encrypted to a different device! I am totally devastated as there are pictures of my father who has passed away and other images that they are the only copies I have, I know now I should have unencrypted the memory card before the factory reset. I have spoken to Samsung directly so say there is nothing that can be done.
does anyone know of a way I can get round this I would be so very grateful!
Thanks in advanced

The best thing I could suggest is a third party solution that may be able to decrypt the information on the card, such as FeExplorer. Check to see if you have a "Decrypt SD card" option in the Lock Screen and Security settings, although I suspect it won't be able to do it.
The problem is, the encryption key is unique and stored in user data. When data is wiped during a factory reset, the key is wiped as well, so even if the user configures the same lock settings (password, pattern, etc) they key would be different.
I am not aware of an absolute solution, but here is what I would strongly suggest you do:
If able, make sure the contents of the card are backed up. Use cloud storage such as Google Drive.
Keep the card in a safe place; maybe put it in a small envelope or something, and mark it in such a way as to discourage accidental discarding or wiping.
Buy a new SD card to use in the meantime while you look for a way to recover the information on the encrypted card.
I am sorry for your loss, and I wish I had a better answer for you.
Edit: Found this on another site, maybe it's worth a try. MAKE SURE YOU BACK UP THE DATA ON THE CARD IN CASE THIS GOES WRONG.
On a PC: Copy (the encrypted and unreadable) contents of the sd card from the phone to your harddrive
On the phone: Settings -> Storage -> Sd Card -> Format sd card (this erases all the data on the sd card but don't worry you have a copy on the PC)
On the phone: Settings -> Security -> Encrypt sd Card (should be real fast since it's an empty sd card)
On the PC: Copy the contents of the sd card onto the phone
On the phone: Settings -> Security -> Decrypt sd card (edit: this may take a while depending on how much data was on the card)
sorry but none of the above "solutions" makes any sense. it is not possible to recover data. encryption key was located /data/misc/vold and /data itself was encrypted, too. Furthermore one can't access /data aka userdata partition.
BUT... and here comes the but.. adoptable-storage usually is DISABLED in One UI
So how is it possible your MicroSD Card is encrypted at all? It's not, except you have installed custom ROM or installed any 3rd party encryption tool (you would remember)
There is a good chance your MicroSD Card is plain exFAT or Fat32 unencrypted file system. I recommend to use a card reader for PC and make a 1:1 dump with gddrescue and analyze the dump with photorec or other file carver solutions.
There exist tools for windows too, for example
https://www.klennet.com/carver
https://www.z-a-recovery.com
https://www.runtime.org
Don't buy any software if your MicroSD Card is encrypted, it will definitely not work.
You can easily check if your MicroSD Card is encrypted by opening raw disk image with HxD hex editor and search for any plain text or series of zeros. gparted or testdisk will tell you if partition table exist

when you put an SD card into a Samsung ultra it asks if you want to encrypt it through their own software, no third party apps were used
True, I realized after posting. Samsung is always bit special, they tried to think differently... In that case your data was lost in the moment of factory reset.

Hello, have an experience that my samsung device were dead and my sd card still encrypted.
Firstly, you have to backup entire data on your sd card just in case.
And then, format your sd card using another device (maybe your another android).
Last, put your sd card to windows device and recover all data with DiskDigger software.
It's work on my sd card, give it a try.. Dont forget to backup all data
