[Q] SD Encryption - Sony Ericsson Xperia Neo, Pro

Hi all
I have a question/problem about my files on SD Card.
When I connect my sony ericsson xperia neo with the pc even if it is locked with a pattern I can still access all the files on SD card from USB.
I haven't found a way to encrypt the whole or part of the SD.
In my previous phone (windows mobile 6.1) there was an option where you could encrypt files in sd so that when i connected it through usb to pc, the pc asked me for password first and then read the files.Also i couldn't read the sd with a card reader cause it was encrypted.
Is there an option to encrypt the whole sd or at least part of it?
If so,how?Do i need to use an extra program from android market?Is there an option to do that from the operating system?

I will search for a way to do so...that is really necessary...I have used symbian and maemo before android...in symbian you can set password for sdcard and it becomes unreadable by pc.

I have tried to find a way for days now. Nothing so far. I read that in ICS encryption will be available. Well,if that's the case i guess we'll have to wait till then.
It's a bit shame though because this is a HUGEEEEE security issue that I dont understand why i don't see much fuss about it!!!I'm amazed!

There r a lots of other issues...in my opinion android is still evolving and there is a long way ahead...even then android is by far the best mobile OS.

Hello all,
So I upgraded the phone to ICS 4.0.3 and it seems I cannot find an option to encrypt phone under settings > security.
What I have found is this:
If i connect to pc through usb I need to enter my screen password in order to be able to read the SD Card.
BUT, when I remove the sd card and enter it to an external card reader ALL data are available.
Is there no option to fully encrypt the SD Card in ICS?
What the heck?

[Q] Dell Streak radomly deletes files after USB connection

I recently upgraded my memory card on my Streak to a 32gb class 10.
When trying to put files (pictures and videos) on the card via the USB cable the files appear to have been copied okay, but when trying to access the files on the Streak they are either missing or corrupted.
I reformatted the card in the Streak and tried again. This had the same effect.
I transferred some files via skydrive and they worked fine. But the next time a accessed the card via USB, the files disappeared again, even though I didn't access the folder in question.
This is the second card I have tried, so I assume that the card is not the problem.
I'm running stock 2.2.
Any help would be greatly appreciated.
What OS are you using?
Even though the file copy may appear complete it may not be. Make sure you use whatever steps are appropriate for your OS to eject or unmount the SD card after copying.
Using Win 7 x64...
I'll have another go and let you know.

I've tried again making sure that I've selected Turn off USB storage from the handset and safely eject from the PC. It still happens.
The strange thing is that it even affects folders that I didn't access whilst connected to the PC (it either empties or deletes the folders).
Totally stumped on this. Could it be a problem with the card? If so, has anyone used a 32gb card that works that they can recommend?
You have tried at least 2 cards, but have you tried a different PC. Is it possible you may have "something" running on the PC causing this.

Make sure that you do those in the correct order. Safely remove from PC first, then turn off USB storage on the phone.
If you can read the card with no problems make a backup and then format the card in the phone. I have seen a lot of cases (and not just with Streaks) where issues were caused by using a card that had not been formatted while in the phone.
Where did you buy the card from? I ask because this sounds a lot like the symptoms you see with faked cards that are really much smaller than the 32GB they claim.

Hmm. I got it from Ebay. It does show as 31.2gb in windows.
This is the second card I've had from this supplier (I sent the first back because of the problems with the streak as listed above). As I had the same probs with the 2nd card I assumed the device must be at fault.
Are you sure the card is legit? you should hook it up to a card reader and loading +20gb of data and seeing if it's good
I tried transferring a load of files to the card and it stopped after about 3gb. Some of the folders were empty.
I tried reformatting in windows and noticed it was FAT32. The card will not format as NTFS.
I guess this means that the card is duff?
it definitely sounds like you got a fake, those are classic signs it's a fake

[Q] Android locked my SD Card

I was backing up files and now the sd card is permanently "write protected." I cant format and cant write to it but the data is still there. There is no lock switch on a micro SD card so that isnt it. Is there a way to get the card unlocked?

Have you tried placing it in a Full Size Adapter with the slide Lock on the side ? Then trying to format it. There is an Article HERE that better illustrates what I mean.
I had the same problem. Windows had problem with formatting it, but Ubuntu did it and now Win see it as "unlocked" too. Made copy of files and format it via adapter on any linux (i think)

I used both the adapter and usb mounting. When I mount with USB for some reason it lets me delete and copy over files but after disconnecting it reverts back to all the same files from before. Its not the lock switch, its something Android did like password protection

ps. does exist an application that cancel all unused application files in the sdcard? thanks again.
1 and 3 sound like a bad sd card or card reader in the phone. The rest sound like an OS bug, which a factory reset should hopefully clear up.

What do you mean "cancel?"
thanks for the answer,
i guess is the sd card, il try a factory reset. the new sd card that caused problem is a samsung 16 gb cas 6, i thoght it was good.
i mean wipe the garbage, like all those files left behind from applications uninstalled and no longer used.
thanks again.

Well, normally when you connect the USB cable and choose to connect the USB storage then the SD card becomes unavailable to the phone but the computer can then access it. Both the computer and the phone cannot access the SD card at the same time... I will spare you the technical reasons but you should know that this is normal. After you are done copying files with the computer then you must turn off this USB storage mode so the phone can access the SD card again and then it will see all your music and pictures again (all these are stored on your card by default).
This should all be fixed OK by a reboot of the phone though in any case. Are you sure you rebooted the phone completely? maybe you should try to remove the battery once?
If you've done all that then you can try to repair the SD card by taking it out of the phone and using micro sd to SDHC adapter and inserting it directly into a computer then using windows to run a chkdsk on it.
hi,
i've done all you said properly, you know the problem came out because there was a differente behavior than in the past.
i remove securely the phone from pc and then is not accessible,
i didn't tried to chdsk the sdcard i'll try, but it sounded strange to me because its brand new.
i also tried to contact htc , they said " try to reboot, or try to remove the battery and the sd and start the phone again, the problem wasnt gone.
thanks for the advice.

Well if it's just gotten corrupted then you can just reformat the sd card. You'll want to backup all your data first so if you can't do that from the USB connection to the PC then you'll need to insert it directly into a pc. Once you've formatted it you can put your backed up data back on the card and put it back in the phone and after a while it will find your mp3s again. If it's truly a bad sd card then the reformat won't help.
Do you have another sdcard? The one that came with the phone or any other? Try putting some mp3s and photos on it and then put that in your phone. If your phone recognizes the photos and mp3s then maybe your current sdcard is the problem. And can you tell the the format of your sdcard? Is it NTFS or exFAT or FAT32? If it is UHS-1 card there is a good chance that it is in exFAT. To make it work on Evo 3d, convert it to FAT32 .

[Q] SD Card Problems

Hi all.
Here's the situation:
I have a 32 gb Sandisk (unsure of the class) sd card I've used with 2 different phones for at least over a year now. I took the card out of my phone to connect it through my laptops built in card reader for the purpose of transferring large files (card reader speeds are much faster than usb mounting through the phone for me). When I put it in the computer Windows wouldn't recognize it. Now it won't mount in my phone at all, and it won't work correctly on my PC. When I connect it to my computer it says the card needs to be formatted before use, but then when I go to format it, it shows up on the Windows formatting screen as only having a 30.6 mb capacity and I get the message "Windows was unable to complete the format" whenever I try to format it, no matter the settings.
So my question is, how do I get the darn thing to work again? I think something must have happened between shutting my phone down to remove it and putting it in my computer. I just don't know what. Anyone else ever experience this? (I've already given up on recovering all of my files, but if it's possible to save them that would be amazing )
Things I've tried:
formatting via Windows
formatting via android
formatting /external_sd via Clockworkmod recovery
a couple different data recovery/partitioning programs (Partition Wizard and PhotoRec/TestDisk
also using "chkdsk" in windows command prompt returns saying that the disk is in the "RAW" format.
Additional info:
Phone: Motorola Droid RAZR HD (XT926) (Verizon)
ROM: XenonHD 11.01 (Android version 4.2.2, AOSP based)
Sorry if this is more lengthy than necessary, just trying to be thorough and cover all the bases!
Thanks in advance for your help!

Sd card problem

my sd card is encrypted,
I made a factory reset,
I turned the phone on, trying to decrypt it it gives me "This SD card cannot be decrypted because it was encrypted on another device..."
Although it's the same device
tried to connect to pc via cable the same thing I got, (It says this is a kind of security and privacy)
I want to get the files on the sd card back but with no success, any help ?
Did you remove the card from the phone before you updated to the beta? This happened to me when i did the Oreo beta last year for the S8 and I had to get a new SD card and re-transfer the files from my PC...
Have you inserted the card into your laptop to see if you can access the files on your computer?
this year i removed the card and before the update to beta and I can see my files now...i hope you can find a way to access the card my friend ...best of luck...

The phone warned you of this (and what would happen) when you encrypted the SD card.
Factory resetting the phone caused the phone to generate a new set of encryption keys (which is why it tells you it was encrypted on another device). As a result you won't be able to recover the data on the SD card.
