[Q] Does device encryption also encrypt internal sdcard on sgs2? - Galaxy S II Q&A, Help & Troubleshooting

Since Galaxy S2 uses a dedicated partition for internal sdcard, is it encrypted too with device encryption? There's the option for external sdcard, but I'm asking about the other.

I respond to myself: encryption only works on stock ROM, kernel and everything, and internal sdcard is encrypted also when phone is successfully encrypted.

[Q] encrypted external SDcard is accessible in recovery without entering password

I'm trying out encryption, and have just encrypted the external SD card for now.
My goal is to encrypt both the external and internal cards.
But to my surprise, I've noticed that the external card is accessible (I can read its contents) from recovery (CWM) without having to type any password...
Which is mind boggling...
How the hell is this possible?
FWIW, I'm using a slightly tweaked samsung ROM (android 4.0.4). Repacked stock kernel.
Thanks
I've got the same question.
I'm on Stock Rom 4.0.4 on I9100.
I was shocked to see that the fiiles on the external SD card are accessible without any Password.
I was under the impression that everything is encrypted.
Anyone can clarify what is and what is not encrypted?
I believe only files that are downloaded to the SDCARD are encrypted, not files that are stored there by some other means.

[Q] Just encrypted my device, did it encrypt external SD card also?

I'm a custom ROM on Android 4.2.2 and used the Settings > Privacy > Encrypt phone feature. What exactly did this do, did the encrypt the internal SD card, the external SD card, the entire filesystem (i.e. root of filesystem), or some combination?
If it didn't encrypt my external SD card, how can I do so? But if it did, how can I access the contents of my external SD card (after providing my PIN/password) from a laptop when I put the SD card in it? Would I just mount it like I do any other encrypted USB drive with LUKS?
If not, then isn't it risky because if my phone gets broken and I must start from a new ROM, then I've lost my most recent data (backups could be a few days old). Or lets's say someone flashes a new ROM, the new ROM wouldn't be able to read the card, or would it be able to if you use the same PIN/password?

Encrypted internal /storage/sdcard0 cannot be read after installing new ROM while using same password, just checked.

[Q][MM+] Adoptable Storage

As all we know, android 6.0 has introduced a new feature called "Adoptable Storage", wich can let you mount your fast enough SD card as an internal storage. I think that's quite easy to use and understand for a normal android user which wont go through flashing. But the problem is I love flashing rom or patches that requires access to either storage in custom recovery ( TWRP 3.0.0-2 ). But according to my experience, when I mount SD card as internal storage, I cannot manage files on the internal storage anymore but I also cannot access to the SD card in TWRP!
My question here is, is this symtom normal or I have screwed up something I dont know?
It is normal for sony devices. On samsung phones(Maybe even others) it gets recognised as adoptable storage in TWRP. Why do you want to use adoptable stoage? Its realy buggy

SD Card Adoptable Storage KEY file lost - Help

Hello all!
I had to do a factory restore to unlock the sim card for my phone. After this I proceeded to doing a TWRP restore and for some reason the partition on my SD card that has all my apps is not being recognized anymore.. When the phone booted it thought my sd card was new? I did noticed that my internal storage is wiped. I have to assume something is missing? Is there any way to manually allow android access to this adoptable storage partition? I am fully rooted and on CFW.
Information:
Galaxy S5
Android 6.0.1
NOTE: My SD card is formatted with adoptable storage.
It appears that adoptable storage utilizes a .key file in the data\misc\vold folder - even doing a twrp backup it came up blank - it seems twrp does not back this up?
wtf - is there ANY way to recover this at this point??

How can i recover data from adoptable sd card?

I was using my 8gb sd card as adoptable sd card(formated as internal) but I replaced with 32gb card and formated new one as internal. Now when I tried to insert sd card in pc it doesn't shows any drive and 2 drive one approx 150mb other approx 7.5 gb is shown in disk management. Both are shown as 100% free. But I didn't formated the 8gb card on device nor on pc. Is there any way to recover the data from that card? I don't have the device right now. I sold it to someone else

The feature called Adoptable Storage allows the Android user to format an external storage media as permanent internal storage to be used with this specific Android device: Hereby Android formats and changes it’s FAT32 or exFAT format to ext4 or f2fs, it gets tied to this specific Android device. The key used to encrypt the data on the SD card is stored on the Android device’s internal memory.
So, it is not possible to mount the adopted storage to another device because of its encrypted nature.

Consider this scenario:
SDcard1 was used in mobile as adoptable
Then it was removed from the device and card was not formated and no device reset.
Then card with high storage capacity was inserted and this new card got formatted as adaptable and but still no device reset.
Now I want to use the old card in this device. Will the device recognize it as it was used there before?
Adoptable storage is a nightmare as cards fail regularly, as you have found out. With an unencrypted SD card, you could run chkdsk in Windows to repair the card. The only thing I am unsure of is if there is an equivalent in Linux. If there is, the card which has an ext4 file system could possibly be repaired.
Try iBoysoft Data Recovery. If a file is a recognizable format, iBoysoft will find it and recover it. (And take days for a decent-sized card.) Instructions are at the software Step By Step. (If each file is encrypted, it may not find anything, but if the file structure is encrypted, iBoysoft never looks at the file structure except to see how large the clusters are - and it can work without that information.
