[Q] Backup encrypted SD card files

I recently had to hard reset my TP2 (but removed the SD card prior). After the reset I inserted my SD card hoping I could retrieve files saved there, but it turns out that neither my phone or PC no longer reads them because they're encrypted - but it's the same phone. I'm not clear why the same phone would not be able to read those files.
After looking through the forum and further research, it seems those files are just plain gone - or at least not able to be opened. Is that true? I could see them on my pc (through a card reader), but could not open them through the phone or pc. My company enforces the encryption on the phone and the card.
So my main question is this: How do I back up these files so that I can retrieve the data on them if I should be forced to do another hard reset? I downloaded some purchased games to the card, some cab files, and a little music. I'm mostly just concerned about the purchased files. If I just copy them to another folder on my PC, don't they remain encrypted?

Windows Phone 7 storage not recognized

I am posting this hoping it helps someone with the same problem.
I had my HTC Surround resetting itself several times a day, finding it without all the configuration (people, email, carrier hubs on the home screen, etc.) and reporting the storage as 15.73 MB instead of the 16 GB. In the last part of the problem, my phone did not recognized the storage at all, no matter what I did.
Windows Phone 7 uses the internal SD (yes, our Surrounds and most, if not all, of the HTC 7 devices have Internal SDs but covered under the phone case http://www.anandtech.com/show/4015/h...cket-boombox/8) as part of the Windows file system, it does not differentiate between on chip storage and SD storate, WP7 treat the storage as a big one, storing all kind of OS configuration (http://support.microsoft.com/kb/2450831/en-us) on it (SD card). Hence when the SD problem presents, the phone resets because the OS can not continue to run due to data missed, and also this is why all the configuration (email, hotmail, also the carrier personalizations, etc.) is lost, because is stored on the SD that is not recognized by that time.
An excerpt from the link above:
The phone’s operating system integrates the SD card with the phone:
•When you start your phone for the first time.
•When your phone is reset to its original factory settings. This is called a factory reset. This is a task that is typically only performed by OEMs or MOs.
When the operating system integrates the SD card with your phone:
1.It reformats the SD card.
2.It creates a single file system that spans the internal storage and the SD card.
3.It locks the card to the phone with an automatically generated key.
So we conclude that the problem is caused by the internal SD not correctly integrated with WP7. In my case a factory reset did not help, no matter what I did the phone did not recognized the card, reporting storage as 15.73 MB. The solution involved opening the phone (I did not care to void warranty, anyway I am far from the States where I bought the phone and can not get a new one. But for you, your best bet is to get a new one, and make a factory reset as soon as you use it FOR THE FIRST TIME, and let the phone finish to do its thing). I had to open the phone, get the SD out of the phone, turn the phone on, do a factory reset, turn off the phone, insert the SD card in the phone, turn on the phone and finally do a factory reset. This procedure had WP7 reintegrating properly the SD. My phone now is rock solid, it has not reseted even once.

Thanks for sharing this. I had this very exact same issue with my developer device, a Samsung Taylor. I even made a thread in the App Hub Forum and concluded that the SD was corrupted. Unfortunately for me, the SD could not be removed as it was super-glued in place.
Another member on that forum also experienced this, so it seems like this can be potentially become a very bad problem.

[Q] How to recover data after factory data reset?

After I upgraded my nexus OTA to 4.0.2, my nexus randomly turned off by itself. So I did the factory data reset, but I forgot to backup my phone. I need help recover my images from before

Once it's gone, it's gone.

If you have a backup, restore it
If you don't, why the heck not? YOU'RE SCREWED.

Yeah unfortunately it's gone. Get Titanium Backup from the market and perform a backup. you can set it up to automatically backup any changes, i think.....I haven't tried that option yet. RomManager will backup your current rom if that interests you.

If you can find a way to mount mass storage (which as far as I know isn't possible yet) you can use any number of data recovery utilities to get your data back.
No removable SD card + no USB mass storage is kind of a major fail and my only regret about owning this device...

Caps isn't necessary friend, if they are on your virtual SD card they should still be there. If you've wiped the SD card you can't recover them.

[Q] My Phone Can not Read content on my SD Card

Hello Guys,
I had to encrypt my phone because of the Company i was working in before. And now when i quite i wanted to remove the Encryption by decrypting, But No, that does not work.
According to Samsung you have to Factorey reset the phone.
So i Did...
After that my Phone does not recognize any content on my SD card. I can not View pictures or Viedos. I can not listen to music or open office files.
If i add something to the SD card i can read and write to it. But i CAN NOT access the old info stored to the SD card before factory reset.
when i plug the the SD card into the Computer, i can not open any of the content, it´s like they are encrypted or something.
Please help.
Thanks in advance.

Well it does say when youre trying to factory reset that you won't be able to access encrypted sd card files as the encryption key will be erased with the reset..
Sent from my GT-N7105 using xda premium

So Stupid!
Yes, i saw that yesterday when i did factory reset again. i thought that if i use same password when encrypting that maybe i will get the same key and can unlock the files on my SD Card. but no... i did not work.
In other Words, the files are not damaged on the SD Card, they are encrypted, right ?
If no one in this forum can help me out, i will save the SD Card for the future.
Maybe technology will be able to solve this kind of issues or maybe i will get to know a nice Hacker that will offer his/her help.
Please let me know if there is an other solution out there.
Thanks.

I don't think anyone will be able to help you here, that's the whole point of encrypting it. Why do you think that your Company insisted on it in the first place?

I need help to recover lost files after hard reset to factory default.

Please is it possible to recover my files, Moto g6 play XT 1922-5. The phone no longer recognizes the unlock pattern. I was using a 256GB SD card as internal memory, which was slowing it down and also had two cracks on the display. I believe that for one of these two reasons the phone stopped recognizing the unlock pattern. I had an emergency situation with my Daughters and I tried to unlock the phone until it went into factory reset mode. The phone started working again and I was able to use it to call but all my files were lost. I also forgot to remove the card so as not to affect it. The phone went from Android 8 to Android 9. I just retrieved my calendar from google. I had gone to two conferences and recorded audio of classes, company qrcodes, photos of equipment and stands. Sorry for the long text and the translation by google translator. Thanks in advance to anyone who can help me solve this problem.

If the SD card wasn't encrypted you should be able to either read or recover the files.
Internal memory is much harder. Consider using a data recover company.

Thanks for listening. The SD card is as encrypted internal memory, I can't read the files. Here where I live there is no data recovery company. Only in bigger cities. anyway thanks for the help.
