[Q] Recover defect SD-Card (Micro) accessing nand flash direct? - HD2 Windows Phone 7 Q&A, Help & Troubleshooting an

Situation:
- My HD2 with WP7(7004) no longer recognize my micro sd-card. I know the best friend is the the backup, but some new picture are not included in the last backup.
- Accessing the micro with a adapter and pc failed. win7 aborting after a while and no drive appears.
- I think the controller on the sd-card is defect. So no accessing with recovery tools.
Idea:
- After some time and investigation i found a special service. The reason for defect cards are to 80% defect controller not memory. They offer to read the nand flash with a direct interface to the chip.
- I Know the sd-card(my) is encrypted, and as far as i know, the key is saved on the HD2 after first install with the sd-card or factory reset.
Behavior:
- Sporadically my HD2 reboots, sometime 2-3 times, but then it boots correctly with saved settings.
Question:
- Whats your opinion to rescue the raw data this way, make a copy to a not defect card and accessing with the HD2 and the key in it.
Of course any other suggestions are welcome.

Are you sure that your photos weren't uploaded to skydrive?
Check using pc and log-in to skydrive using your windows live id

Hi Robbie,
no way, because SkyDrive was not activated. I have made some videos that were to large for my 500 mb volume rate.

Its going to be difficult to copy the card because of the encryption you mentioned.
Its difficult enough to format it! Most OS don't recognise it.
The link you mentioned would only return to you a load of stuff.
Not sure what you can do, sorry.

[HOWTO] Partition SD card

Introduction
Transcend and several other manufacturers make 4GB SD cards these days. They're great if you use your HTC device as MP3 player or Camera, as they offer enough space for thousands of songs and pictures.
My device, the HTC Universal, handles them just fine. However some applications, most notably the Camera application, don't like it.
Why some apps don't like it
The main problem here is the way in which they calculate the free space.
the processor is 32-bit, which means it can handle numbers ranging from 0 to 2^32. 4GB is exactly 2^32 bytes, so that shouldn't be the problem.
The problem is that applications sometimes handle the number as signed, which means that it differentiates between negative and positive numbers.
With signed numbers, the last bit is actually used as the sign (positive or negative), and the new range stretches from -2^31 (-2GB) to 2^31 (2GB).
Up to 2^31, the unsigned numbers and signed numbers are the same, but after that the last bit is set in unsigned numbers, which means that if treated as signed it will be seen as a negative number.
So if you have more than 2GB free, and the application mistreats the number of bytes free as being signed, the application actually thinks you have less than 0 bytes free
How to fix this?
There are several ways to fix this. The most simple one would be to have a simple dummy file so you always have less than 2GB free. This works for the camera application, but any miscoded application taking a look at the actual size of the disk will still screw up
The other solution is partitioning your SD-card. This means that you actually split the SD-card up into several virtual SD-cards of smaller sizes. So one SD-card of 4GB could be seen as four of 1GB (my set up).
This way you still have 4GB of storage, but applications will not get confused as it's split up into several chunks.
WARNING
Before you start remember to back up the current data on your SD-Card. the procedure will completely erase your SD-card. You might be able to retain the data by using partitionmagic's resize partition features, but you'd have to test yourself.
Also I'd like to mention that although I tested this procedure myself, I can't garantuee it will work for you. If it renders your SD-card useless, I can not be held responsible.
My set-up
This tutorial was written using:
- T-Mobile MDA Pro (HTC Universal)
- Windows XP SP2 MCE (equivilant to Pro)
- Transcend 150x 4GB SD-Card
It might work with a different set-up, but I can't garantuee anything
Requirements
- Windows Mobile 5
- WM5Storage (do not use CardExport2, you need the ability to turn off "Removable Class"!)
- Big SD-Card
Let's get started
Just follow the following steps
First, make a backup of your SD-card! the following procedure will erase it!
Next, install WM5Storage. I will attach a copy of version 1.53 with this post, but you can get the latest version here.
Just copy the .cab file to your device, and execute it from the file explorer. Just make sure you install on the main memory, as the SD-card becomes inaccessible during the procedure
Start WM5Storage. On my device, WM5Storage did not put anything in the start menu or the today screen, so I had to launch it through the file-explorer. You can find it at My Device\Program Files\WM5Storage\.
Be sure to untick both "Read-Only" and "Removable Class". Optionally you can set it to light a LED on read/write, but that's not neccesarry for this procedure.
Disconnect your device from your computer.
Insert the SD-Card if you haven't done so already
Hit "Activate" (bottom, right)
Re-connect your device to your computer.
From now on all steps are done from the PC
Wait until windows has recognized all "new hardware", and you have new a new hard-drive listed in "My Computer".
Open the control panel (Start -> Control Panel)
Go to either Performance and Maintenance -> Administrative Tools (category view) or directly to Administrative Tools (Classic View)
Double-Click Computer Management
Go to Computer Management (Local) -> Storage -> Disk Management (might take a little while to find all drives)
In the bottom view, find the disk that has your SD-card in it (You can find out by looking at the contents through "My Computer", or by seeing which disk is added once you plug in your WM device)
Right click the partition (white block ), and choose for Delete Partition
In the just created "Unallocated" space, right click, and choose for New Partition
In the wizard:
choose for a Primary Partition
For size, enter 1024MB (or if there is no more remaining, just the remainder). Ofcourse you can also choose your own size
Assign any drive-letter you want (or none if you only want it to be accessible on the WM Device).
Format the partition as Filesystem FAT32, Allocation unit size Default, and pick any volume label you want (You will only see the volume label on the PC, on the WM Device it will just be "Storage Card X". Also tick "Perform a quick format"
Wait until the bottom line in the new partition reads "Healthy" (wait for it to format basically )
Create as much partitions as you'd like (just resume from right-clicking and picking New partition)
You're done partitioning! If you want, you can fill the contents of the SD-Card now before you deactivate WM5Storage
Disconnect the device from the computer
Next few steps on the Device
Click "Deactivate" (same place as "Activate" was before )
Close WM5Storage
You're all done! have fun with the multiple storage cards you have now
Afterword
I've put quite a bit of time in this tutorial, I'd appreciate if you at least told me if it worked
If you can spare a few coins, I'd also appreciate a donation. You can donate with PayPal to "[email protected]".
nice post, i'm bloging it right away 8)
I have a 2GB SD card. My o2 mini prompt me to format it when inserted. After formatted. o2 mini shows 0.01 MB only.
"My computer using card reader shows 14KB and from Disk Management, it shows 1.86 GB Free. I believe this "1.86GB Free" means unallocated space.
I right click on the unallocated space, but there is no option for me to choose a Primary Partition. It only has 3 options.
"New Logical Drive...",
"Delete Partition...", which is grayed out and
"Help".
Help! How to allocate this 1.86GB and format it to fat32?
Any kind soul please help me get this 2GB SD card to work with my o2 mini. 1.86GB and not 0.01MB.
Thanks
is there anyway to rename the partition with a different name? i've tried a lot of ways but in vain... the 2nd partition always follow the name of the 1st partition... any help please?
thanks in advance...
non
After having lots of problems with my SD card, I already thought that partitioning possibly could solve the problem and, using your howto, I can use my 2 GB SD-card without any problems.
Thanks!
ive done this on a 512 sd and using wm03, used a card reader to do the partition.
actualy worked well for a while if you have alot of files to store in one of the partitions, but ended up being a real pain when you wanted to re-do it
Really nice post and easy too.
thanks
hi i tried it.....realyy wonderful....thanks a lot for posting this one...keep posting things lik tis.....
cheers,
Siva....
thx for this tips!
I used it for my 2GB MiniSD card, but now I would like to keep my TomTom maps on the second partition, but TomTom can't recognize the map. (Storage Card2\)
I tried by editing the 'CurrentMap.dat' file and set the path to the Storage Card2 but still TomTom doesn't want to read this second partition. Anyone a solution for that?
thx!!
Nice tutorial. I have problem with reading of my 4GB SD card. Now I'm using two partitions (1GB for cameras and 3GB for my PocketPC). Thank you
I have been trying this but all I seem to be able to do is partition the card but only able to format the first partition s the rest of the card is rendered useless
Any help appreciated
Great tutorial, will link it up from my related articles!
partitioning 4GB help
Hi,
I've followed you instructions (great job, btw) HOWTO partition SD card....using the file download WM5torage.cab For some reason, I cannot get past the part after clicking on ACTIVATE immediately after inserting the SD Card. My MDA (TMobile Wiz) keeps locking up and I have to do a soft reset. I've tried reformatting the 4GB Mini SD card a few times and I've actually gotten different results. My last format (FAT32) shows (on PC) 1930MB free and 1931MB used which befuddles me. I formatted it again and it showed 3.78 GB free. Perhaps you or someone could assist me if possible. I bought the Mini SD card off eBay from a reputable seller. It was suppossed to be a Samsung 4GB Mini SD card and I was a bit surprised when it arrived as a SanDisk. Any idea as to why the phone keeps locking up? I also wonder if there might be an issue with the card...I examined the back of the card where the contacts are with magnification and the sides of the black composite show traces of perhaps an epoxy or bonding agent...I think SanDisks QC is better than that. To make things easier, you can also email me at [email protected]
I have cingular 8125 and vista. I tried to use the program wm5storage but when I go to computer management there is not recognition of the 4 gig sd, nor is there any recognition of an sd when using my pda. Anyone know how to get the phone to recognize it (I tried reformatting) so that I can partition. Thanks
I have had some success with 4 GB cards from IntegrityElectronics and TopRam on my T-Mobile MDA running latest TMO ROM.
The problem I am running into a when using apps that are installed on the card and write dat to the card, other files get corrupted and render those applications unsuable. If I limit use to playing MP3 and videos, thing tend to stay stable.
Has anyone else observed this behavior?
Ok, I used the storage program to access the card. Then with the disk
management on XP I formatted the card as FAT for the entire 4gb card.
It looks like it worked. I copied all my files to it. Everything is running.
I have done several restarts with no problems...
Hope it stays so.
Good luck folks. I will report back if anything weird happens.
Ok. So it all got completely screwed.
I guess it got corrupted. My guess is when
I started using the camera. All of a sudden
there are only blank folders on the storage
card with a period as the names. Tons of them.
Nothing else. Any ideas?
And now I cannot get wm5storage to work.
It keeps telling me that something is accessing
the card. Any help would be greatly appreciated.
Thanks.
It seems the problem was that there was a hidden Recycler folder on the storage card that would not let me use wm5storage. Probably from
Resco File Explorer... Deleted that with my PC...
Somehow magically my pc read the card. I don't know how to explain
that seeing as it was formatted in FAT not FAT32...
Then wm5storage worked and I paritioned it into 2 halves.
Lets see how that goes.
I hope, well.
This may be a silly question but...
Can't you plug the micro SD into a card reader and use Windows XP Disk Management tool (or any other partintioning tool) to create the partition on the storage card? What's WM5Storage actually doing?
SG
Anyone? Can't one just soley use the Disk Management tool in Windows to partition a SD card?

Changing Shift HDD to CF Card Disk

Check out this site, it's the guys from Mobile01 again trying to replace the existing HDD to CF card disk, you will see the RAM and HDD in closer view.
Result......? it doesn't work, because after install the CF disk, it needs to proceed to re-install the OS, and the OS is store in the original HDD, guess this guy didn't find a solution into this. However i do believe we will be able to sort this out in the near future.
Also replacing the RAM is currently not possible, there are no 2G module out there for sell yet, I guess we need to wait for the Hardware to catch up.
Go and check out the pic in this link:
http://www.mobile01.com/newsdetail.php?id=5414
how about cloning the disk to CF first ?
Maybe use a clone proggy to clone the actual HDD to the CF card first, then mount / solder it ?
Maybe i'm too dumbed down by windows OS'es, but if you clone the HDD bit for bit to the CF card, my guess is that it will boot straight away.
Maybe one needs to fiddle a little with the MBR, or the device ID, but that should be it really.
Please keep us posted.
Are the installation files on the harddisk?
I read in another thread that the installation files are in ROM soldered to the motherboard and that all you need to do after installing a new harddisk is to press FN F3 at bootup to restore Vista. This might be wrong and I'd actually wonder what the hidden HD partition would be for if it should be true.
Anyway, if they didn't make any mistakes installing the CF card, they should be able to install Windows from a USB drive.
However, have you seen what they installed instead of the 40GB HD? A 8GB CF card. This will never be enough to hold Vista, so I wouldn't be surprised if that was the cause for their problems, the installation routine might just balk at "insufficient space".
As the linked website is using Chinese (I guess, or is it Japanese, Korean, ...) characters and language, somebody able to read this would have to evaluate what they are doing.
Swop hdd
The problem with swopping the hard drive is it has since been discovered that the drive is artificially sized down to protect a HIDDEN partition using special features of IDE drives in conjunction with the BIOS.
I'm aware of no program on windows that will clone this special hidden area as the drive removes it and it is only visible on boot. However linux can see there is a hidden partition but i'm unsure not knowing much about linux whether it can clone it.
If you simply swop out the hard drive you will lose the ability to FN+F3 on boot to restore the image.
I would suggest therefore you do the following before the swop out.
1. Boot Shift
2. FN+F3
3. Do a full factory restore
4. Switch off when directed
5. Attached external USB CDROM/DVD drive
6. Use BartPE
7. Power on Shift and boot immediately to BartPe
8. Once booted insert a usb hard drive / key using the 3-way hub, so you have the cd and hdd connected via USB
8. Ghost / clone the drive from C: to your external hard drive / pen
You now have ghost image that you can restore to on the new hard drive (ie. not a FN+F3 restore process but a CLEAN ready to initial boot installation of Vista).
Regards
Blitz
The vista installation files are in a hidden partition on the hard drive.
This is why the 40gb drive shows as a 34.2Gb drive.

The reason why they install 8G CF card is for faster read/write speed, and i guess it will also decrease battery usage since it's not mechanic moving like the original HDD.
Thanks very much wu5262 - I fully understand why they want to use a CF card instead of the harddisk .
I was pointing at the meager 8GB size they picked.
If you want to install Vista, use at least a 16GB card. If you can get your hands on one, use a 32GB card (admittedly not so cheap). For an example: http://www.amazon.de/Components-32GB-CompactFlash-HighSpeed-Karte/dp/B00162ZOPW.

Corrupted SD Card

Hi,
What happened
Yesterday when I had more time I started installing some applications on my HTC Touch HD.
I installed:
1).NET Framework 3.5
2) Advanced Configuration
3) Total Commander
4) Gyrator 2
I had already installed IGO 8 a few months ago.
After installing Advanced configuration I tested the IGO and it was working, I had no problem.
However after I installed Gyrator 2 and with Gyrator 2 on I tried to start Igo8, the IGO8 didn't want to start. After further attempts and investigation I came to the conclusion that the SD Card is corrupted.
Symptoms of the SD Card(original one that came in the box with the device):
1)While reading it from PC only the root directory of the card is visible with all the folders inside but I can access only one folder out of 15. for the others I get an error, cannot read from the device...
2) From the HTC touch HD I can even enter all the folders but while accessing some files, not all of them, I get errors saying that the files could not be opened.
3) I had to do many restarts so only two times the first screen that you see after you power-on the device is the "Smart mobility" and then after a few seconds you get the details of the ROM and two other rows in the bottom right corner. So for two times the "Smart mobility was not centered" as well as the bottom right corrner data they were not at their position. However now after 5-10 more power-on power-off manipulation the first screen seems to be ok.
Possible causes as I see it are two:
1) Gyrator 2 and IGO8 do not lik eache other very much, and some how when IGO8 started maybe the orientation of the screen just changed from portrait to landscape. It is just a theory, as I'm not an expert I cannot say if it's correct or not.
2) After installing the Gyrator2 I have somehow unplugged the USB cable while the computer might still have had a connection to the PC. That's ulikelley because I allways do the "Remove USB device" before unplugging, but I did it so many times that I do not remember exactly that time. However I trust my instincts even though I cannot exclude the possibility of an error.
The cause 2) might be realated as well with the usual problem of choosing the action needed when you connect he HTC Touh HD trough the USB cable. It happened many times that an option is preselected(read the Storage card) but I want to actually synchronise the device with ActiveSync, so initially the PC opens the SD card as an external drive and then after I click on the phone to choose the ActiveSync connection it closes the external drive and makes the connection.
Is there a better way to choose between the modes of connectivity to PC, taking into account that when you want to install some software on the device you have to either copy the file on the device itself and start it there or install it on the PC and use ActiveSync to install it as well on the device.
My main question is related with the helthcheck of my HTC Touch HD.
a) Is there a risk that the internal built in flash storage of the device is corrputed as well? I have checked all the files almost with no problems of accessing any of them. It seems ok to me. The only thing that worries me a bit is the problem with the splash screen as I explained it under possible cause 2) which now doesn't seem to appear anymore.
b) is there any other part that I should verify to make sure that my device is ok.
c) Less important, if you could help me find out what happened to make sure that I won'trepeat it again and break the next SD Card.
d) Can I recover/repair the SD Card itself, the data that I had on were not very important I have them on my PC in proportion of 90%. I downloaded some tool from SanDisk called usb-test-tool.exe but it fails to see the card(I think the tool is not the right one), or I shouldn't even bother because there is a risk of having problems afterwards.
Most probably I'll have to buy another SDMicroCard I'll try to buy the same brand maybe for 16GB, I do not know the prices yet.
Sorry for the long pot, but I wanted to give allt he details.
Thanks for your support!
And now most probably I'll have to uninstall the applications that were installed on the SDCard, I hope it will work out and there will be no left-overs in registries or on the filesystem.
coincidence
well. Mine got bricked too yesterday. it was a 16GB sd-card. Only my phone can access it and the data is gone. Data was firts messed up (like chaotic named folders and files) and then disappeared. I can create new folders and files there but it is full of lost chains and clusters (found by mobile apps) and reports the same free space as before (40%) but there are no content visible. When I connect it to laptop either as an disk drive from mobile or directly with sd-adapter I get high cpu usage of interrupts and a frozen usb managment and need to restart.

Same happened to me with my 16gb Sandisk card.
Card reader said is was write protected and could not format using SDFormatter.
Solution after a search found on the Raphael forum was to download http://www.cnetx.com/format/download.asp and install to main memory.
Success !
Then I could read it and formatted again with SDFormatter
Hope this helps

encryption question

on on htc touch hd go to start >setting>system
you then have the encryption tool that says when you activate it
"encrypted files can only be read on this device "
so may be a daft question but when i have this activated can i connect my phone via active sync or as disk drive and still see the files and open them and my memory card ?
what im trying to get at is if anyone found my phone they can read the files as they have the phone. what has been encrypted ?
thanks
I'd say no
I'd also say reflash with another rom and you can't read it ever again
even hardreset the phone and you can never read it again
it's made to make sure you're most secret stuff never gets out if you're phone
is stolen not to make sure your stuff will ever be something you can retrieve if something goes wrong
are you saying that you think the encryption is not working ?
No. That's not what he's saying. He's just advising that you not use it. The encryption key is stored on your phone's memory, so that if you ever hard-reset or flash another ROM, the encryption key will be lost and you won't be able to access the data on your memory card, ever again. You would have to do a full format of the card to even be able to use it again.
thanks for clearing that up .
could you recommend any software that i can install on the phone that requires
password to access the memory card while still in the phone and require password if memory card was taken out of phone and put into a pc memory card reader
thanks
I don't really know of anything that would be compatible across multiple systems/platforms like that
I just googled this and found the following software:
http://www.aikosolutions.com/encryption/secubox-encryption-vs-windows-mobile-encryption/
Just some thoguhts for using the native encryption...
I wonder if the encrytion key can be extracted from the phone...?
That way it could be added again on another ROM. Also, the key could then be used in a desktop application that implements the same algorithm (AES, I think). This would allow the card's contents to be accessed outside of the phone.

[Q] Can the Acer a500 support any other Android OS released except Honeycomb or ICS?

​hello, I accidentally deleted the /sdcard folder and now it appears that i've lost all my data. So, i've deleted the folder by mistake from windows explorer and the tablet "auto created" a new one and none of my data shows up. I've tried about a dozen recovery programs but none will recognize my tablet. How can I make it show in Windows 7 like a Removable Device and not like a Portable Media Player. I kown it's more of a windows question but maybe someone else here made the stupid mistake i did and kowns how to slove my problem or please send me to a forum were I can get some help.
ps: I kown not to write anything on the tablet's storage until I solve this.
ps2: i don't actually have a sd card, all my data is on the internal memory.
Thank you!

​Had some free time lately and did some research and I found out that the reason I can’t access the internal storage through software like recuva or other data recovery sw, it is because Honeycomb uses MTP (Media Transfer Protocol) instead of UMS (USB Mass Storage), like android did until honeycomb and data recovery software doesn’t work on MTP, or at least none of the ones I’ve tried, and I’ve tried a few. So, I decided to change the thread question to: Can the Acer a500 support any other Android OS released except honeycomb or ICS (I read it uses MTP also)? and: Can the internal storage be accessed by a recovery software on Linux or any kind of OS? plus: Did anyone manage to recover data from internal storage through any method?
Ps: I don’t need a full working rom, just the touch screen or a mouse so I can mount the internal storage.
Ps2: I would have tried it myself, but I don’t have the knowledge(all I could think about was to download the rom from other tablets that run on 2.3) or the time to joggle with roms on my acer so if any of you developers out there could help me I would be in great debt to you.
Have you tried these apps? (seems you need root though)
I don't know if they will work, but just trying to help you out (I too have deleted my internal memory, but it always happened while ROM flashing... forgot to back up my files first).
https://market.android.com/details?id=fahrbot.apps.undelete
https://market.android.com/details?id=com.hexamob.hexamobrecoverypro
https://market.android.com/details?id=com.hexamob.hexamobrecoverylite
(^ the free and possibly not as good version of the one above it)
Also, on the W7 computer, have you tried Recuva?
Again, not sure if it will work, but I have used it for memory cards, flash drives, etc and it worked really well.
I think the biggest challenge though would be the way that the computer reads the tablet. It doesn't appear like a normal external USB device.
So, I think that an app will be your best bet. I think too that Android keeps apps*, OS*, and user data (your pics, movies, documents, etc) on separate partitions, so installing an app shouldn't overwrite any of your old stuff. I am only 90% sure of that though. :/
*It may actually be apps + OS
Were you rooted??? Did you make a nandroid backup??? If you have a nandroid back up you can restore just the data partition from recovery and you will be current as of your last backup. Another major reason to root your device.

My thoughts were that Samba acts as a server and would be used with wifi to show as local network share on your pc. Then to use a program to recovery your files. I think that idea is not possible after further checks. Seems none of my recovery apps will recover from network drive. Some will save to Network drive though, but that doesnt help you.
One of the apps from the market spexwood suggested may be your only hope.
I would suggest getting an sdcard and save your photos and videos on it.. much easier to recover if erased.
​Had some free time lately and did some research and I found out that the reason I can’t access the internal storage through software like recuva or other data recovery sw, it is because Honeycomb uses MTP (Media Transfer Protocol) instead of UMS (USB Mass Storage), like android did until honeycomb and data recovery software doesn’t work on MTP, or at least none of the ones I’ve tried, and I’ve tried a few. So, I decided to change the thread question to: Can the Acer a500 support any other Android OS released except honeycomb or ICS (I read it uses MTP also)? and: Can the internal storage be accessed by a recovery software on Linux or any kind of OS? plus: Did anyone manage to recover data from internal storage through any method?
Ps: I don’t need a full working rom, just the touch screen or a mouse so I can mount the internal storage.
Ps2: I would have tried it myself, but I don’t have the knowledge(all I could think about was to download the rom from other tablets that run on 2.3) or the time to joggle with roms on my acer so if any of you developers out there could help me I would be in great debt to you.
