encrypted virtual drive - MDA III, XDA III, PDA2k, 9090 General

hello,
I am wondering if there is an application that would run on the ppc6600(unmodded) that could create a "virtual encrypted partition" on the SD Card that would request a passcode to access.... then after a period of time, if the drive is not accessed, the drive would become re-encrypted automagically.
thank you for your time

Formatted SD to NTFS, any way to get it back?

Hi everybody,
I have a huge problem (for me anyway) and I can't find a solutions (i've searched for 2 hours now!). I hope somebody can help me.
I have a Sony Ericsson Xperia Arc S rooted. Basicly I wanted to transfer a big file on my SD Card. Without thinking i converted my Fat32 SD Card to NTFS with the command prompt in Windows XP. After converting I could still see all my files etc on my laptop.
When I disconnected the phone from my laptop, the phone couldn't recognize my SD card anymore and offers me to format it! So I figured I'd change it back, but I'm not able to connect the phone to my laptop trough USB, it just doesn't offer me the option.
When I insert the SD Card trough a MicroSD adaptor in my laptop, Windows won't recognize the disk either, and offers me to format it to a 512 byte disk - the SD Card is 16 GB.
I'm really freaking out now since there is alot of important documents and photos on the SD Card. Is there any way to force connect the SD Card trough the phone with the USB Cable? Since the files were available before disconnecting, i'm sure they're still there.
I tried 2 partition recovery programs (testdisk and File Scavenger) but they either recognize the Card as empty 512 or 1024 byte.
Is there any way I can format the SD Card back to Fat32 trough USB, or just even recover the files on it?
I hope my stupidity can be solved painless
Thanks in advance...
Didn't you make a back up of your files when you converted it to ntfs? Doesn't Windows normally format the card when you change its file system?

I have a feeling the SD card might've gotten partitioned... ie. you have two partitions on there now instead of just one. Open a command line with the with SD card connected to the computer, do this:
diskpart
list disk
select disk #(get the disk # from "list disk")
clean
That should get you back to a single-partition sd card.
Does windows give you any clues in the disk management section?
Right click > My computer > Manage > Disk Management
Download minitool partition wizard and then plug in your sd card and open the program. Then delete every single partition you see (ON THE SD AND NOT YOUR HARD DRIVES) and then click create a new partition and then format it to FAT32 and you are good to go !
Had the same problem with a flash drive
right click on drive > properties > readyboost > uncheck the box. Try to format the drive again.
Oh boy... The convert Fat32 to NTFS cannot be undone.
The tool was included with Windows XP for those Upgrading from Windows 98, who would still be runing FAT32 on their hard drives. It allowed them to upgrade to NTFS without loosing any data...
Unfortunately, the only way to get the card back is to Reformat it. I'd recommend the Command Prompt, and the Command would look like this...
Code:
Format /FS:FAT32 /X (drive letter):
The /FS switch tells Format.exe to format the specified drive in a specific file system. In this case, we're forcing it to setup a FAT32 partition on the disk.
The /X switch tells it to dismount the drive before formatting. This makes sure that nothing else is currently using the drive, so that nothing else can mess with the drive while Format is working with it.
After the drive is formatted, go download some decent data recovery software (I've always had good luck with iolo Search and Recover, but your mileage may vary) and have it scan the drive to recover your media.
Also... DO NOT MODIFY THE DRIVE IN ANY OTHER WAY! IF YOU WRITE ANYTHING TO THE DRIVE, COPY FILES TO IT, CREATE FILES ON IT, SAVE THINGS TO IT, YOU WILL LOOSE ANY DATA YOU PREVIOUSLY HAD ON THE DRIVE! Naturally, formatting the drive has a chance of doing this anyway, however, the automatically detected sector size should match the original sector size, so the chances of loosing everything are slim to nil. All hell breaks loose when you start adding and removing things from the drive...

Bitlocker corrupted Internal SD storage

I plugged my phone into my new Win 7 laptop at work. I needed to copy some files. It said I had to encrypt the drive to be able to copy files. I figured I'd have to decrypt the drive after I copied the files for things to work properly again.
During encryption, Bitlocker froze. Then my phone froze. Long story short, I can't access the internal sd card. USB mass storage won't turn on when I plug the phone into my laptop. I'm fine with losing all data that was on the card...I just want it to work again. I can't save anything to the internal sd card. It's as if it's not there. Maybe it just needs mounted?
Any help is much appreciated.
I think I got it figured out.
I flashed back to EL26 from AOKP and the encryption picked up where it left off. So hopefully I'll be able to decrypt it and still have all my stuff.
bitlocker destroyed my Galaxy Note...
Did this work? I've had EXACTLY the same problem!! Hassle is I don't have admin rights on my computer at work so it's going to be awkward getting someone to decrypt the drive... :-/

[mini-Howto][Live CD/Linux] SD Card Recovery Using Testdisk

So I have an old SD card that for some reason or another I keep using because I haven't gotten around to replacing the replacement I did get that doesn't work (sad tale of a Sandisk Class10 32GB card that I've seen from a handful of other people).
Anyway, I've had to do this a number of times now and it's worked pretty well. First of all, if your disk is crashing this way, there's probably something wrong with it, and there's a chance that your data will not be recoverable, or it will be recoverable and it is corrupted and it might take time to figure out how it's corrupted.
Basically, I get a warning from Android that there's something wrong with the SD disk and apps rely on the SD card will slowly stop functioning until it crashes. After this it pretty much just locks up and is unusable. This is the procedure I use when there's no partition information on the drive and the disk just appears to be empty. I run Linux on my systems so I just use run testdisk natively but there appear to be some Live CD's that have testdisk installed for everyone.
Mount your SD Card following your usual methods with a USB reader of built-in laptop card reader. Hopefully you have one.
Figure out which /dev represents your SD care. Normally I just open gparted (probably some variation of just finding it in your system tools or gksudo gparted or gparted from the command line). If that's not an option some combination of the following may give you some info to help you figure out which disk is causing the problem.
Code:
ls -l /dev/disk/by-id
ls -l /dev/mm*
ls -l /dev/sd*
The nice thing about gparted is that it will show you which partitions are formatted, and if your results are like mine you will see your ext4/ext3 SD-ext partition has survived with your apps intact, but no dice for the storage portion of your card. You could mount your SD-ext partition and copy the data if you wanted, or use dd to copy it but you have other backups, right? Oh, your Titanium Backup files are on your SD data drive. You don't rsync to a server..? OK, we'll get to that...If you want a chance of recovering your files remember your /dev path (why you opened gparted) and close gparted before you do something stupid.
Start testdisk in your favourite terminal emulator with... wait for it...
Code:
testdisk
And this is the part where I tell you exactly what to do but can't actually remember and always just bumble around until I find what I'm looking for - so I Googled it for you.
But to summarize after starting the program, you'll need to select the correct disk (/dev) and tell testdisk what type of partition your disk uses (pick intel!)
You can try using analyze to write a new partition table. This doesn't seem to help the problem I have with my disk but it hasn't hurt my recovery efforts either. Make the copy first and then try to recover partitions after, just to be safe.
To get your files back you want the advanced menu and the undelete option. Say what? Undelete?
Basically this feature is meant to let you copy deleted files off a camera card, USB hard drive etc. so once it's done it's voodoo to read the files on your broken partition it will show you all the files on your partition, not just the deleted ones (in red). Several filesystems will just leave junk on the drive until it gets overwritten later so many of these deleted files may be partially overwritten already.
Just highlight everything, if you can manage to not highlight the red things you're ahead of me.
Now press "c" to copy the selected files just like the program tells you. Follow the prompts to choose a destination folder. You probably want to copy it all into an empty file so it's easy to copy back.
If you copied all the deleted files on your disk you probably deleted a bunch of junk you no longer need and will needlessly fill up your SD card with files when you copy everything back. You might want to clean that up now.
Put the SD card in your phone and start fresh with a full format of the SD card in 4ext recovery.
With you newly minted partitions ready to receive data, you can use the toggle USB storage button to put your data back on the phone. I believe this is the recommended way to write data on the card. This will put all your backups/ROMs on the SD card so you can reflash everything and start recovering your data from your backups. You do have backups, right?
Hopefully this helps someone!

[Q] How to encrypt & decrypt your phone + SD card?

Hy,
I have a couple of questions... If I want to encrypt the data of my phone+sd storage, I do it in the settings and set the pin/password.
But then there are things I find disturbing/dont know:
1: When select encrypt sd card, all is greyed out and my pc doesnt recognise it anymore. How do I copy my images to the pc?
2: If I encrypt the phone storage also, how can I access this?
So what I'm wondering is that, how can I even make backup if I cannot access storages through pc?
I though there is option for decrypt (with your passcode) ?
Thank you for your answers
There is probably a better way, but for me i just use dropbox to sync everything to my pc's.

Android 8.1 can't move App to SD

I can't move app to my SD, only External storage format. Someone have the same trouble?
I mailed Nokia customer support about this issue and eventually got the following reply:
Greetings from Nokia Mobile Care ! We are sorry for the inconvenience that you are facing!
Please kindly keep in mind that the Nokia 6.1 device, as well as all other Android 1 devices, do not have the option for Internal storage formatting of an SD card. Additionally, there is no option for forced formatting of an SD card as such.
We hope this information managed to answer your inquiry. If you have any further questions please do not hesitate to contact us again!
Still waiting for an explanation as why the User Manual says that Apps can be moved to the SD card.
I believe in the reviews I read that Nokia chose not to implement "adoptable storage" in the 6.1
This is a trend in some new phones which is not welcome.

In Developer options (tapping 8 time on build number it will be present) there is a item at the end for Forcing app on external SD thal allow install app on SD. I don't know if it is working or not but try it and see if can help

That option only force apps that normally can't be installed on SD card to be able to move, but we are not even able to move apps which can be moved.

From the AOSP site: "Caution: On devices running Android 7.0-8.1, file-based encryption can't be used together with adoptable storage. On devices using FBE, new storage media (such as an SD card) must be used as traditional storage. Devices running Android 9 and higher can use adoptable storage and FBE." Fingers crossed that when 9 rolls out for the Nokia phones in the Android One program, that adoptable stroage becomes an option. (again, the ability to use both fbe and adoptable stroage only affects phones in the Android One program, why? I don't know)
Adoptable Storage now available, but corrupts files!

The Pie update is finally here (Build 00WW_3_260_SP01) and it is now possible to format an SD Card as "Phone Storage" (aka "Adoptable Storage") but doing so WILL CORRUPT YOUR FILES!
Here is how to do it:
Format the SD Card using something the device won't recognize (NTFS, EXT4, etc.)
Turn off phone
Insert SD Card
Turn on phone
Tap the notification about Unsupported SD Card which brings up the storage options with a Format this SD Card? dialog popped-up on top of it
Tap CANCEL on the Format this SD Card? dialog to see additional options
Tap Phone storage in the Use for extra phone storage part of the screen
You will see another Format this SD Card? dialog that looks identical to the previous one
This time, tap FORMAT SD CARD
You may get a warning about the SD Card being too slow. Ignore that and proceed.
After the format completes, you may think you have working adopted storage, but you don't. Files written to /sdcard (which now points to the removable SD Card) will randomly be corrupted. One way to see the corruption is to tap the Move content button after the format above completes. If you had a lot of data on your internal SD Card (such as hundreds of pictures), much of it will now be corrupted. You were warned.
Another way to see the corruption is to use the adb utility to push files to /sdcard on the device. When you pull the files back, many will be corrupted. It's quick and easy to see the corruption using images (I push about 570 of them) and then launch Google Photos.
Which is worse, not supporting adoptable storage or supporting it and corrupting our files?
