I’m wondering if there’s a way to make the whole sd-card encrypted and the android system recognizing it as an external sd card? The purpose being that data is safe if the phone would get lost/stolen. I’ve been looking into this guide using cryptsetup, but it only works with an image, and only part of the SD card.

My SD card is nearly full ~55gb/64gb. I am wanting to encrypt the SD card, but it only encrypts new files. Can I move these files to an external hard drive, enable encryption, then move them back over all via a PC? Will it then encrypt all the files? Also, is this something I really want to do? How will this affect me in the future when wiping/flashing/updating roms? I understand I need the decryption code. Do I just enter that when flashing a new ROM?
Thanks for any heads up.
I just got a 128GB SD card and I decided that it is a good idea if I encrypt the SD card, since the device is already encrypted. I didn't encrypt my last card, just for the record.
Anyway, I'm familiar with how Android Encryption works, I know the risk, I backup my phone regularly, and I know that putting the SD card DIRECTLY into another device or PC is not an option, anymore. Only my G4 can read/write to the SD card while it's encrypted.
Problem is this, I ASSUMED that so long as the SD card is in the phone and the phone is plugged into my PC, I could make file transfers between the SD card and the PC (the phone would handle the encryption process). No such luck. I have no way to transfer files between SD card and PC, unless I decrypt manually.
Any suggestions?
I just can across this same issue last week and have been hunting for an answer with no luck. Have you found any?
I though i could move files around internally and the OS would handle decrypting the files as they went from the SD card to the internal storage. I was a bad assumption. I want to encrypt the SD Card, but I cant move files onto or off of it.

Phone and Ext SD Card (64 gb) Encrypted
Problem: Accidentally deleted 5 mp4 files from ext SD. Have been vigilant about not writing data to card.
Solutions Explored: 1) Droid Apps 2) PC programs
Tried numerous apps and programs but they are going to require me to root the droid as they aren't turning up the goods.. I'm in the middle of a backup of internal and external storage, which will take a whole day, plus ---- in case I have to give in to the root option. I've done jailbreaks and roots before, successfully, but have no desire to run that risk. I like to have a vague idea of what I am doing so resist one-click routes but am willing to go in that direction if others here might assure me of just the right solution.
Solution Considered: Decrypting SD card then mounting via usb and running recovery programs, which don't otherwise recognize the phone (internal or external storage) even in the usb mass storage mode (PC recognizes all phone storage for file management just not recovery programs/apps). Would decryption overwrite crucial data (file content of deleted files) or only higher levels?
Update: Ext SD Card was NOT encrypted
I unmounted ext sd card. Connected to PC via usb card reader.
The phone indicated that the card was encrypted but it was not. I see earlier threads here where this happenned in kit-kat and jellybean. Now, add lollipop.
What gives?
Galaxy Tab S ext sd card not encrypted
Device says the card is encrypted. I checked via card reader because of experience with phone. Same deal. Not just file names and metadata but file contents are recognized. NO encryption. Does the unmount make it readable? What's going on?
Hi I was hoping someone would know how to do this.
I have a slight issue on my HTC One M8 the charging port isn't working anymore and I will get the port replaced.
However in the meantime the micro SD was used as internal storage I have a lot of media on there I wish to keep and when inserting the SD card into a pc or another phone it's unable to read the SD card. Probably replacing the port once its fixed will solve the problem but in the meantime does anyone know of anyway how to view the contents of the SD card from inserting the memory card into a pc?
Help with this would be much appreciated thanks.

You can't do this (mount on PC) once you've selected to use the SD as internal storage. That is the whole point of using it as internal storage, the SD is an "extension" of the phone's internal storage. Only part of the files are on the SD, and some are on the phone's built-in storage. And the way computers write files, there is nothing saying that the fragments of a file are in any one location (part of a file may be on SD, part may be on the phone's built-in storage).
Stated more simply, the SD is now just part of a whole. By taking it out, you now just have a part of the whole; therefore breaking it, so it can't be read on a PC.
That's why there are two options given in Marshmallow when you insert an SD, to format as internal or removable storage. You can't have both. By picking internal storage, by definition, its not removable (can't be read by another device once its removed).

Thanks for clarifying I have the port in for repair and the technician said he won't be hard resetting the phone so hopefully I'll be able to still get into the SD card after.
Hi all,
i've put an new SD card in my HTC 10. It was said that it would be encrypted, so i thought great, and also that it would behave as an extension of the internal storage, therefore many apps could be installed.
On the contrary, if it is formatted as an external storage, then not all apps accept to be moved onto it, so that even with a huge SD card, i may face a space problem on the internal storage at some point, if i install too many apps there.
Question 1 though: are the photos/videos/screenshots/music etc really stored on the SD ? Or onle once the internal storage is full ?
For example, one of my videos is on /storage/emulated/0/DCIM/100MEDIA/MYVIDEO123.mp4
Is that the SD? or the internal? or is there no possibility to know just from the path?
Question 2: is it true that if i factory reset the phone, the SD card will also loose all its data, photos, videos etc ?
If that is the case, is there any real davantage of using an SD as internal storage ?
A positive scenario i would see is to use it indeed as an internal storage and do online backups of my photos/videos etc.
For the moment i was quite happy with my previous phones to use the SD as external storage and the data there being unaffected by whatever system changes on the phone. A bit like two partitions of a PC. One for the OS and one for the data.
While if i merge the two, even if i can see the advantage of doing that, it's again the old-time merging system and data.
How do you guys deal with that ?
Thanks a lot,
Adrien
About Question 1, you can format it as internal, put that video and simply unmount or eject card. You will see what happen. You can always format that card as portable so you don't lose.
About Q2: From what i know, yes. It's true, because your card is treated as internal storage, so it will be wiped and after that your phone will "say" that your sd card is corrupted. You will need to reformat SD card.
IMO Adopting SD Card as internal memory is a bad idea, at least for me. OK, you will have encrypted data and unusable in another phone, but SD cards aren't "speed demons", and for me SD cards are intended as portable data storage, not as internal memory.

Thank you ShadoV90. That makes things clearer for me.
