ever since I lost the mini-sd card in my old 6700 on a restaurant floor I've always thought encrypting the memory card was a good idea. I keep alot of personal data on the card that I wouldn't want in someone elses hands.
Now that I moved to the Tilt I've turn that feature on and password locked the phone. Over the weekend I thought of a couple scenarios ... and now I am questioning the feature.
If for some reason I had to hard reset my Tilt, would it still be able to read the encrypted micro SD card?
Is the key between them software or something bound to hardware that wouldn't change in a reset?
For Proto732
Hello,
For "If for some reason I had to hard reset my Tilt, would it still be able to read the encrypted micro SD card? " :
If your Make a hard reset on your Kaiser your lost your key Encryption so you can't read you sd-card encrypted.
No Probleme on soft Reset.
Private69.
@++++
The key is stored somewhere in the phone. If you were to able to find it and replace it after a hardreset, it ought to be ok.
Anyway, for me, I would keep my stuff in my phone Notes encrypted (i.e. use my software - on signature), or just one of the freeware wallet.
Thanks for the answers ... I found this also for anyone else looking for info on Encryption:

Hi,
I have a tmobile wing and I got the phone a few days ago.
This is my first windows mobile phone and therefore i don't have much experience and knowledge here.
I am facing a problem that has surfaced three time in the last week or so. The applications that i have on my storage card become unavailable and when i try to open the applications i get an error saying that sd card is not available. Also starnge folders with strange names (a lot of different characters such as boxes appear on the storage card and i am unable to delete them, where it says that there are system files in these folders).
The problem is only resolved if i do a hard reset and format my storage card by using a card reader (format of the card is essential as even after doing a hard reset the storage card does not become available). Initially i thought that it was some problem with the applications that i had on my phone but now since this is the third time that this has happened I am worried that there may be something wrong with my phone. Since my phone is still under warranty i can return it. So please advise rearding the same. The applications that I normally have on my phone are as follows,
a) Resco file explorer and Registry explorer
b) SK Tools
c) Opera Explorer
d) Mio Maps
e) Google Maps
f) Space time
g) CE Convertor
If this has something to do with the offical wing ROM, please advise which ROM to use as again I'd like to iterate that I am totally illeterate regarding this. What I want is a ROM that gives me plenty of RAM so that I can run my GPS software and MP3's at the same time, other than that there are no special requirements and I don't need plenty of pre-installed applications.
Thanks for your help!!!

Did you set your temp for IE to the SD?
This tends to do it for me.
Yes I read somewhere that this helps and I did shift my internet folders to the storage card.
So is this the culprit??
Do a search for SD Card Corruption and you'll find this is a very common problem
These are just a few topics from the Herald forum only ... but if you search the whole site, you'll find alot more. Basically, you can't install anything onto your SD card that needs to run all the time... so anytime ur phone hibernates, if you have a program running from the SD card, it will corrupt your SD card.
Corrupt SD card
MicroSD keeps coming up with corruption
virus on wing!?!?
Thanks a lot for your help, i guess i will be more careful now.
I make a weekly copy of my whole storage card in case I lose everything. I'd suggest doing the same.
I also had the SD card corruption problem. I upgraded to WM6 and it has not happened again
You should knock on wood.
Hi Faisal Aswk,
I had the same problem for many days when i first purchased my Wing. The folder names used to get corrupt and the applications could not be accessed. At first i thought it was the ROM. I tried several ROMS but the same problem resurfaced. Then i was led to believe that my microSD card (Kingston 1gb) was going bad. I then bought a Sandisk 1gb. Everything worked fine with the Sandisk. No corruption for weeks, up until one day i formatted the Sandisk card using the windows format utility and the corruption reappeared. Later i did some research and found out there is special formatting on microSD cards to be able to function properly with devices. I assumed the Kingston did not have that sort of formatting. I reformatted the kingston card using a panasonic utility suggested by a user in one of the XDA forums. Here is the link...
http://panasonic.jp/support/audio/sd/download/ftp/sdfv2002.exe
I am using the Kingston MicroSD now. 3 months till date and no sign of corruption. I have both PIE and Opera Cache on there. I have several MP3 files i keep moving around, stored and deleted several 500+ MB movies files. All my applications are installed on that card.
I cannot say for sure that it was coz of the special formatting, but i have strong hunch that it is. Hope this fixes your problem and for others as well.
This issue is on an AT&T Tilt.
The phone would not see the SIM card and therefore all dialing and data connections could not be made. Along with AT&T tech support, we attempted to remove/replace the SIM card, soft resets, clear storage, and finally a hard reset with no SIM connection success (he told me it appeared to be a mechanical failure with the SIM port and they are sending me another phone Monday).
My problem is when I try to access saved photos, notes, spreadsheets, CABS, and other various files both on my reset tilt and the memory card; many of the files/photos/etc. are locked.
Is there a way for me to retrieve these files? I encrypted the card in Nov of '07 . . . I was under the impression that the same windows based mobile device could open the files.
Is there something in the clear storage or hard reset functions that prevents me from retrieving the files? This is EXTREMELY disconcerting considering the fact that some of the files are there and visible ???
When I tried to re-sync it to my laptop I didn't see any kind of a restore feature that could retrieve all the data or at LEAST open the files on the card ??
Anyone familiar with this situation? I'd like to retrieve/unencrypt my information so I can successfully transfer my memory card and all it's information to the new phone before I receive said replacement phone and have to send my defective phone into AT&T.
Thanks for any assistance.
Anyone have suggestions on retrieving the locked files?

if you read the instructions that the encryption program gives you when you click to encrypt files on sd it tells you that if you do a hard reset you will no longer be able to decrypt the files.. because hardresetting deletes i the "key" that is needed to decrypt the files ... so as far as simple terms go NO you are sol'ed. Now you could search google and see if someone has been able to do a "hack" or create a hacking program that can undo encryption but i don't know what luck you will have. I know, atleast haven't come across, anything here on xda of that nature.
This was my biggest fear. I totally forgot that I encrypted the card until I attempted to access the card after I hard reset.
What sucks the MOST about this is nothing software related caused the SIM failure; it was all mechanical. So a hard reset was not even necessary.
I've been using a 6G ScanDisk card for the last 6 months, without any problems. I needed to move some files from the Tilt's internal memory to the Card, and to my surprise there was only a folder named "FilesToBeDeleted" on the Card. I DID NOT CREATE THIS FOLDER! Oh, and by the way the folder was empty!
Checking the storage of the card from the Memory Setting of the PPC, shows about 3 G in use, which is about what I had on it.
Can anyone shed any light on what could have happened? I can re-format the Card....but is it going to loose data again? Is this something that has happened to others?
Thanks for any help,

i have read that this has happened to some people .. not me yet (fingers crossed) don't know what causes this. You could try a recovery software and see if you can get the stuff back.
Can you or anyone suggest a recovery software? Checking the MicroSD on my laptop shows 2.88 GB being used, (and of course 2.78 GB Free) so the data should be there. I have also saved additional data to the card and it works fine.
Just wondering...is there some kind of virus out there that would do this? For all the data to be "hidden" and a new folder to be created....the card just didn't create a folder by itself....
WM a card killer
The same thing happened to my 4GB SD card in Blue Angel (twice ). It seems to me that WM kills allocation table while writing to the card. I tried lots of different soft to recover my card and finally PC Inspector File Recovery did the job. I used card reader and this soft on PC to recover most of my files but the folder and filenames were sometimes messed up. When using PCI FR do not mark to many files to recover/save at the one time because it crashes.
Don't save anything on your card before recovering !

Yup, I used that program too. Recovered "missing files" problems on my previous hw6515 and twice on my TytnII 8GB micro SDdisk.
I've always had that "FilesToBeDeleted" folder too, it's normally hidden and when I delete it it comes back. Nothing special, just some folder the system wants there for some reason apparently, just like the other couple of hidden ones like WMDRM. If you didn't see it before and it now appeared it might have been hidden and the same thing that corrupt the FAT unhid it for some reason.
If you can see 2.88GB used on the PC, are you sure you have also have forced hidden files to display? Your data might be there but just hidden for some reason.
I have also saved additional data to the card and it works fine.

NEVER EVER do that to a media with a problem you might need to recover data from. This might just have ruined your last chance. On the opposite, when possible like on SD cards the first thing you'll want to do is set it as read-only.
When files are deleted, only their reference in the file table are, but the data itself is still present on the media, which allows recovery. But the locations the data is saved on are now marked as free, and anything you'll write on the card now can overwrite it, causing definitive loss.
Thanks a ton!!! The PC Inspector program worked great!! I was able to recover my files Next step, I guess, is to format the card and use it untill it decides to wipe my files out again. Of course my failth is the card will never be the same, and I'll keep a back up of the card also.....actually I was foolishly keeping the back-up for my Tilt on the card...can't trust that method anymore!
Thanks again for all the advise and information. As with all problems, you can always treat them as "learning opportunities", or...... throw the d*** thing out a window!!!!!
Same problem here, just ran into it last night and it's driving me nuts. Is there a way to recover/format the card from within the kaiser? Unfortunately the card reader I have has a max size limitation of 2gb and the card I'm using is 4gb - lame. Any suggestions? Thanks.

Borrow, lend, or steal another card reader.
When I purchased this MicroCard, from ScanDisk, it came with a SD adapter plus a USB Card reader. I threw the USB Card reader in my desk thinking that I would not need this. I found out, by accident, that this USB card reader was the only way I could read the card on a PC. Built in card readers on both my home desk top and laptop would not access the card....
Just passing on this little bit of information, because it never occured to me that I had to use that USB Card reader!
This happened to my girlfriend's phone too. One day some of her programs just didn't work and most everything was gone on her card. Never fixed it, just reformatted card. Scary though.
Yeah, I tried recovering the data using TestDisk, saw some recommendations for it from others with the same problem, but wasn't able to get anywhere with it unfortunately. So in the end all I could do was format it and start over. Ahhh, backups... if I'd only made one.
I think this is a WM issue. Since other devices have the same problem.
here is a quote from another thread
Dutchman said:
I have the same issue with my tytn2.
Sometimes when i play some mp3s from my SD card and the device goes to standby or the program is closed my SD card is suddenly empty.
Removing the SD card and put it back in usually fixes it, sometimes a softreset also works.
So i believe this is a WM issue

Has anyone had the issue while pretty much not ever using Windows Media Player mobile? I was playing DRM'd audio files, is that possibly a common theme?
Could it be Moving PIE Cache?
Happened to me too. 8GB card. Just getting back up and running...wish I had read this last night. I put a bunch of stuff back on the card. Oops. Oh well. I think the common thread may be:
moving your PIE Cache to the SD Card.
Anyone else with this problem also move PIE Cache? Used Memmaid 2.0 to change it.
different in my case, I haven't changed any of the cache settings for PIE.
Hi Guys, I had a problem with my phone so i did a hard reset and lost all of the stuff i bought the phone with i got 99% of it back with the help of the threads here. Thanks Guys! but my memory card slot on the phone will not read the card through the pc or the phones software. please help!
Have you verified that the SD card is working? Try it somewhere else?
Yes i put my card into my brother in laws sidekick and he could play all of my files and i put his 2 gb micro sd (not hc) and my tilt read his card fine so i think one of my settings files is screwed im kind of a noob to winmo but im alright at windows
I would suggest that first you put the sd card into a PC, and check the file system on it for errors and repair them if any are found. That will often take care of the problem.
Otherwise, like my tilt, it could be a hardware problems. I can no longer read SD cards at all, even though the phone knows when I insert and remove a card, it won't recognize it as storage.
My unbranded htc hd7 has been working perfectly for a couple of weeks now, but recently started to have problems. I switched it on after changing sim cards (which i believe i did perfectly, didnt drop or do anything wrong) and it then says..."storage card cannot be read", not allowing me to go any further. I then try to hard reset the phone, which gets the phone to start up with no problem, but now says it only has 12.5mb of storage available (my sd is 16GB, and is the same one issued with the phone).
I've already counted my losses with the stuff i had on it and i'm willing to format the SD card if it means fixing this issue. But Is there a way to fix this via bootloader or something else that will not void my warranty by me having to physically dissasemble it. Your input is very very much appreciated...
There is an option in Zune which lets you wipe all your data on the sd card:
Settings\Phone\Synchronization Options
Nah that didnt seem to work. When i click on erase, it erases the 12.5mb doesnt seem to find the sd card
Sounds like the SD card has become unseated or corrupt somehow
Let me know if you find a way of formatting the SD card without removing it.

Thanks for your input.
I suspected the same thing, so i removed the back cover and the battery, then used a "caveman fixing tactic" of banging the bottom part of my phone with my hand (didnt want to damage it by hitting it with something harder and again didnt want to open it), and its working. Tried banging it again after that to see if it will stop working again but seems to be fine now.
I know this is just a minor (silly) fix and will go to htc to complain about this fault and see if its loose in there because i've never hit the phone hard before this (besides hitting on my hand of course, which is the first and last time i'm doing it) and nor have i ever dropped it. I still havent ruled out the possibility of a faulty sd card, or an error that seems to be appearing with others after the recent NoDo Update.
hd7 sd card issue
I have exactly same issue, the first time (from new) i turned on it did see the sd card and then i inserted a SIM and did a reset and now it just reports 12.5Mb memory always. I have opened it, voiding warranty to remove the 16gig sandisk card and re-insert it many times but still doesn't see it and yet never reports any error like 'cannot detect sd card'. Next i flashed from O2 to a unbranded ROM (from this forum) and still the same and now doesn't even detects the SIM! Next i tried a new 1gig sandisk card.. still does see it (not sure format is required for wp7).. the orignal 16gig card cannot be read or formated on a PC tried using a pc dos format, low level format, sd format programs but pc never assigns drive letter to it.. so hd7 is scrap unless someone can suggest something to resolve.. i suspect the SD card interface from phone is faulty.. gona try the banging on table method next and hope is smashes to bits put it out of its misery!
Had the same issue with my phone. now stuck in bootloader mode. now have given up and using lg optimus one.
Mine is doing the same thing only showing 12mb even with the stock sd card. Did anyone ever get this fixed?
What version of WP do you guys are on? I noticed after each update, the system seems to grab more space on the card. That said, there is a option in Zune settings to change the available storage via slider, may be you have got that set to 12gb somehow... May be try to change it and c what happens then. I personally don't have this problem, even after modifying my hd7 so I can swap sd cards as needed (hard reset required but kind of useful)
Sent from my HD7 using XDA Windows Phone 7 App
I modded my hd7, too. But I never had this problem.
Did you mod with goldcard method or hspal/rspal???
the sdcard has password on it and can only be read through the phone unless you somehow did something to file system and lost the password than you can fix it.
Fix 12 MB
it fix my sd
enjoy your HD7
