[Q] How to encrypt SD card on lollipop and unlock in Windows - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi
In looking for a way to encrypt the phone and SD card and still be able to view/edit the files on Windows. I'm not looking for the best ever encryption, but rather an invisible encryption that do not limit the use for the person having the encryption password.
The dream scenario is:
Turn on phone and type in encryption password only on boot
Use screen lock as long as phone is on
Being able to use the phone as a 'USB stick' dragging and dropping files in Windows
Being able to dismount the SD card, typing the encryption password and view/edit all files on the card in Windows/other android devices.
Is there any way of doing this, e.g. by using and app and store a similar windows program in a small non-encrypted part of the SD card?

HTC Encryption?

Can someone give me info regarding the "Encryption" program included with most Roms?
It allows encrypting the contents of the microSD card, so that if someone steals it from you he can't read it.
Beware this means the files on the card can then only be read by your phone, if you want to insert it in a card reader hooked to your PC the files will be unreadable, and if you forget to / can't disable encryption before hard resetting your phone, all the card's contents will be lost.

[Q] Problems with SD cards / running Honeycomb

Hey guys, I think this should be a pretty simple question to answer but I can't find anything specific when I search google. I've been having trouble running different builds of Honeycomb on my nookColor: v2, 2a, and honeybunches all would not let me connect to wifi. Everytime it would go to connect, the signal would drop to zero and nothing would happen. Any thoughts on this?
Also, since I only have 2 microSD cards I would use Easeus to delete the partitions on the disks and then use SD formatter to reformat the cards so I could install a new build of Honeycomb to check the wireless. However, the capacity of my 8GB card has gone from ~7.6-7.8GB to 7.46GB when i am trying to format it for the next time. Easeus shows a 7.647GB unallocated partition, but the formatter wants to format it to 7.46GB. I don't understand why it has gone down, and it makes me worry that I unwittingly lost space on my SD card. Have I screwed up my cards, or can I get this mystery space back? Please help!
Remove SD card from Nook and boot into stock. Insert SD card, go to settings, Device Info, SD card, unmount sd card, then format sd card. This will/should delete all partitions, format and restore all usable space on the sd card. From here, download and burn the honeycomb image to your sd card. (I recommend ubuntu, dd command. Open terminal, navigate to the directory that contains your nookhoney image. Once there type; "sudo dd if=nookhoney02.img of=/dev/mmcblk0 bs=1M" without the quotes. Note that nookhoney02.img could be nookhoney02a.img or the honeybunches image depending on which you are using and mmcblk0 could be mmcblk1 etc. depending on what the name of your sdcard drive is.) After the image is done writing, power Nook down, insert sd card and boot Nook. Also, the burning process can be done from windows using winimage and what not, the whole ubuntu thing was just my recommendation. Hope this works for you, any more questions, just feel free to ask. Also, I apologize if this is repeat information, just giving the full experience.
just use dd command in linux or osx will erase all the partition, don't need format or erase the card first.if you do so the sd size will not decrease.

Have you tried turning WiFi off and then on again? This seems to work for me when wifi is acting weird.
by turn off, do you just mean press the wifi button in "Wireless & Networks" or the enable disable buttons in the dev tools? i've tried the first solution to no avail. I guess I could try messing around with the dev tools.
The nook doesnt have to be rooted for me to run this off my SD card right?
EDIT: I just went over to B&N to check if their wifi works. It does, so i don't know what the issue is. Possibly because my university uses 802.1x EAP for their network? The only thing that is fishy is that my nook at stock would connect fine.

Answer to your first question yes turning off and back on in Settings>Wireless.
I know I had mine working on my uni's network which has 802.1x but can't remember if it was stock, Froyo, or HC. Not currently on campus so I can't try it for you.
Google "SD formatter" and download the application. It's free and very easy to use and will format your SD cards.

That's what I was using, but the size seems to keep getting smaller and smaller. I'm losing about .01GB per format.
EDIT: Okay now the wifi is working in the dorms, and i hate to say this, because it's so humiliating, but I think i was using the wrong password to log into my wireless network. Which is probably why it hung on connecting. Which makes me feel dumb.

Well at least the wifi is working for you.
Have you tried formatting the SD with the Nook itself (assuming you're running off stock ROM?

[Q] SD card encrypted - How to recover?!?

My Z3+ was acting strange after OTA to android 6.0, so decided to repair with PC companion.
I did backup but didn't backed up SD card, at that moment I thought it wouldn't be necessary because repair doesn't delete anything.
And it's true but I completely forgot that my phone was encrypted, also the SD card.
So now I can't use my SD card files. Any one know if I can get encryption key from my backup? I know the unlock password but I suspect it uses another one that was on my old system
Thanks!

SD-Card wants Password after Start or Restart

Hi to all,
got the problem on my P9, that after i switched it on, the SD-Card wants a Password.
There is no Password given under Security and the only choice is, to cancel the pop-up, but this results in no SD-Card.
I tried the Card on the PC under Windows 7 and it works well. I tested it, copied a few things and all is okay.
Back inside the Handy and switching it on, the Pop-Up shows up again.
After a Restart the Card will be accepted, sometimes i need to restart it for 3-4-5 times, before the Card is recognized.
Any one a Clue?

External SD card encryption falsely reporting that card is encrypted!!

I have a Verizon branded Note 8 that I got from Verizon directly. I run an MDM (Mobile Device Management) application for work and was setting up policy for Android devices when I discovered this. I required external SD cards to be encrypted. MDM software kept reporting that my phone's external SD card was not encrypted, after I had gone in and encrypted it. So I reformatted the external SD card via the Note 8 itself. Android notification says that SD card is encrypted, just as it did before. However the MDM software throws a warning that it is not encrypted. I contact the Vendor of the MDM software and they have me pull the card out and check the contents from my PC. (why didn't I already think of that, I assumed it was the MDM falsely reporting the card as not encrypted). Once in my windows 10 PC, I am able to open and browse all files on the SD card. Damn. The phone is reporting the SD card as encrypted but it is not. This was a brand new SanDisk 200GB Micro SD, never used in anything other than the Note 8 and now my Windows PC for the encryption verification test I ran. I did a chat with Samsung support and they told me to try another card but either way the phone is still falsely reporting that the SD is encrypted when it is in fact not. I tried the process 3 or 4 times with the same result. Anyone notice this same issue? Anyone verify that their device is in fact encrypting their SD card by placing the card into another system? Seems like a big deal for a company that touts KNOX as a Secure implementation for Android phones.

How did you format the card?
Maybe try removing card, putting in Winblow$ PC and running diskpart...
Code:
list disk
Code:
select disk (x)
Code:
clean
and thats it.
No new partitions or anything. Just put it in Sammy Note and let it take it from there.
Worth a go?
The card was formatted in the Note 8 itself, then the encryption utility in Settings was used to attempt to encrypt the card. After the attempt, all appears to have been successful from the perspective of the phone. However the card is fully readable in my Windows PC, using the laptop's built in card reader. I could try all of those things but it still doesn't resolve the issue that my Note 8 gives an Android notification after boot up that my SD card is encrypted when in fact it is not. Thanks for your response.
Hmmm... Will try on my Exy and report back...

Bump for you.
I feel your pain in the opposite way. I encrypted my phone and keeps turning off when booting up phone again.
