how to recover data from the formatted memory card - General Questions and Answers

i have heard many people complain to me that they just format their memory card accidentally on which a lot of important files have been saved. they are so upset because of the data loss that regret for a long time. i myself also have formatted the memory card by error and felt terrible when knowing all information have been lost. and it was more than one time, actually. i have tried to find out many ways to get those files back from the formatted memory card[/URL]. Finally, i got how to complete that task. i want to share it with you guys:
We can get back those lost files with data recovery tool from the accidental or intentional formatted memory card. Data recovery software could retrieve that data within a shore time. Here are its steps as follows to show you how to perform:
Step1. Download and mount the data recovery software on the computer.
Step2. Insert the formatted memory card to a card reader and then connect them to the computer on which the data recovery tool installed.
Step3. Double click the data retrieval program and choose the recovery model. Then select the object disk to scan.
Step4. You can preview the restorable contents in the list after the scan. Preview them and choose the wanted to recover.
Step5. Select one of the computer hard disks as the location to save the files to be restored.
there are precaution to avoid such data loss trouble, in fact. that is to back up those files regularly.

While it's nice that you decided to spend the time to write a guide, this thread will probably get buried extremely soon unless if it's stickied.

Should I allow my PC to scan and fix my internal SD card?

A few days ago I entered phone hell. At the time, the phone was on the last stock upgrade from AT&T, wasn't even rooted and didn't have a custom recovery. Short story is that it soft bricked out of nowhere for no apparent reason. I finally gave up on fixing it, installed TWRP recovery, did a Nandroid backup, wiped everything twice and reinstalled stock through Odin. Fortunately the Nandroid backup recovered my data and my apps, so I was able to selectively restore through Titanium.
Now that even though both the internal and external SD cards are more than 50% empty, I can't do anything like update apps or sync gmail because of insufficient storage. When I connect it to my PC, Windows Explorer recommends that I scan and fix the card. I suspect that whatever Windows is seeing caused my brick and the lack of space issues.
Is it okay to let Windows do the scan and fix?
Long story short? No...
Enable hidden files and folders in explorer and find the directory that is eating up the space.
Either that or USB connect it, copy everything over, disconnect and wipe from phone (settings > storage > erase) and then reconnect and copy everything back

Safe Full Backup of internal memory on Windows

Hi,
I'd like to copy the entire internal memory partition (sdcard) of my opo to my windows computer.
I tried doing with regular file transfer (MTP) with usb cable, but each time at some random point pc can't see phone anymore and the transfer gets interrupted, and I have to start over because I cannot be sure exactly which subsubsub...folder copied last.
I tried doing with adb pull, and I get almost the same result also with some corrupted files.
So I'm asking: how do you copy large amount of data from/to phone/pc? Is there some kind of tool to manage data trasfer, i.e. with checksum verification, pause and restore if lost connection and so on, to make sure that when the process is completed all data is intact and I won't find "bad surprises" some time later?
Thanks

Decrypt SD card after factory reset

Hello,
I unexpectedly had to do a factory reset on my S7 while the SD card was encrypted, as result the SD was not obviously readable afterward.
I saved part of the encrypted content of the SD card (basically the pictures) before formatting it and starting using it again, however I'm not able to recover this content.
I tried with the procedure I found on internet:
- saving the encrypted data
- format the SD card
- encrypt of it
- copy of the saved content back to the SD
- decrypt
However, at the decrypt state the phone don't move from an 'Analyzing SD card' phase.
Any idea? I'm afraid I should have saved all the content of the SD card...
Thank you
You should plug the SD card on to your PC using an SD Card reader. Open up CMD, and type diskpart.
After which, type list volume, and you will see the "drive letter" of your SD Card, type clean and afterwards...
Proceed to typing create partition primary size = "insert capacity of SD card here (mb" *w/o the quotation marks*
After which, type assign letter=F
It should work fine after this hopefully.
When you encrypt the SD card, Android makes a unique key that is stored in the Android trust store. When you factory reset the device, that key is lost. Permanently. Remember, the whole point of encryption is so malicious parties cannot access your data. If you could just read it again after factory resetting then there isn't much point is there? Your only option is brute-forcing it.
Always backup. Always.

Thank you
I do have a backup, however it was more convenient to restore the 20GB of photos from the SD rather than from the cloud.
I was reading some guides on internet with this procedure that's why I tried.
I will survive, thank you both for your answer

If somehow it was possible to backup the encryption key which is generated randomly on each phone then it would be possible to decrypt it on your PC even if the phone was damaged using your password and encryption key. For some stupid reason this is not implemented in Android (but it was doable for some devices), for example TrueCrypt or Microsoft Bitlocker allow it.

Yes, I thought the encryption was based on pin of the phone actually.
Lesson learned
Hello,
I have similar problem, but with Sony Xperia Z5 Compact. I made factory reset but didn't decrypt SD card before. SD card was ejected before reset, so I have all the datas, but cannot open them.
Is there any chance that I may recover my photos and videos if I don't have any backup?
Best regards.
Anyone?
Hi everyone
I kinda have the same problem. But the difference in my case is that I didn't reset the phone. While operating normally, one day it gave me a notification that encryption has failed. When I touched it, a page opened with the button of decrypt SD card at the bottom. I thought a restart would fix the issue. But when restarted, the contents of my SD cannot be accessed. I tried to decrypt it manually but in the settings, it thinks that the SD is unencrypted and only gives me the option to encrypt it, which obviously fails after every try. I was wondering if there is any way to trigger the decryption manually? Because I didn't reset the phone or anything and the data is still there. The phone just fails to see it.
Thanks in advance
Hey! I can confirm for 1000% the method you said worked for me:
- saving the encrypted data
- format the SD card
- encrypt of it
- copy of the saved content back to the SD
- decrypt
I deleted a video was able to retrieve it using Diskdigger on my pc. But then I was unable to open it because it was encrypted. So than I decrypted the SD in my phone only to find out the files were than unrecoverable deleted!?! Luckily I copied the files to my pc before decrypting!!! I used ur method and it worked decrypted it and everything played fine! Must say I was on the same os same phone(s8) so that must've been why it worked anyway still it worked. I'm happy, I acquired parental responsibility because of u?
I have made a similar stupid mistake I rooted my galaxy s8 and forgot to decrypt the SD card... now can anyone help me with the steps that I can fallow to decrypt the camera folder...
I to have a same problum ..
please any one find out the result of that data recover from encripted sd card from samsung a50

Help for recovery of encrypted data from formatted SD card

Hello Guys,
Yesterday my phone (Samsung S7) fell and the screen and touchscreen is not working since then. Not surprised given that it is shuttered XD.
Anyway, I had an sd card in the phone with all the photos saved on it, without cloud backups. Not remembering that the card was encrypted, I have simply connected the phone to my pc and copy pasted all photos to a pc folder. The sd card has then been inserted into a new Samsung A20e and fast formatted.
My problem is that now I have all the photos on my desktop which are encrypted and can't be opened. As soon as I realized this I have removed the sd card from the A20e to avoid overwriting data in case it can be recovered.
I would gladly appreciate if any of you could tell me if there is a way to recover this data.
I can access the USB debugging mode on the S7 and navigate its files.
My inexperienced ideas were:
1. Is it possible to recover the encryption key from the files in the phone and then use this do de-encrypt the photos on the pc?
2. If I insert the sd card back into the S7, format it, encrypt it (through a pc screen mirrowing tool), copy the photos form the pc into the card would the phone be able to read them? This could be possible if the phone uses always the same encryption key without changing it.
3. Is there any use in trying to use one of those data recovery tools on the sd card? The data I would get will still be encrypted.
Thanks to anyone who'd be willing to help.

If it has been formatted, it is gone. Recovering data that has been deleted is quite possible. Recovering data that has been formatted is not likely. And even if you did manage to recover any of the data, it would be very fragmented and incomplete, in other words, there wouldn't be enough left behind to recover anything that is a complete or useable file, all you would have are incomplete pieces of files.
However, it is possible to decrypt your encrypted backup but I don't know the best method to do so.
I only posted to give you an idea of what is possible and what isn't.

Thanks for the reply.
At least if you say that is possible to decrypt the files there is some hope for them. Have you got any idea of where I could understand more on how to do it?

How To recover my photos from my rooted android

Hi i recently made a backup with wondershare mobile trans and it created a .BAK file of 30gb and it is corrupted i don't know why, I can't read videos and photos (if you know any way to access the data in it even if it is corrupted please tell me), i tried extracting it with winrar but it only extracts 6gb of some photos , the rest is corrupted it can't finish extraction.
I flashed a new rom and orange fox recovery , i have root access , i installed disk digger with full root access but it can't find any photo (not a single one) in my internal storage , is there any way to recover my photos from internal storage ?
I flashed my phone before knowing The backup file .BAK was corrupted
If you flash a ROM then Android's internal storage memory - who is surprised ? - gets completely overwritten, means previously stored data have been lost.

I formatted internal storage before flashing the new rom
Steps to recover your deleted data from your rooted Android device-
1. Connect Your Android device.
2. Launch Android Data Recovery software on computer and choose 'Data Recovery'
3. Choose file types to Scan
4. Preview and restore lost data from Android phone.
Stop using your phone to prevent new files from overwriting lost data. Then try to use data recovery software to detect the photos from internal storage. If it can be detected, recovery is simple.

I tend to think it's a lost cause especially if the drive is zeroed out when you flashed.
Don't know but...
This wouldn't surprise me as it's a wise precaution to ensure a clean flash/load.
Even if not overwritten the file structure is lost as that was certainly overwritten when you flashed it. All you will find at best is completely random disjointed files.
The images will have no metadata ie time stamp etc. If you have hundreds, thousands of random images just forgetting about them becomes the less frustrating option many times. There's no way to index them except by memory, one at a time.
Been there, done that
