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

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!

I have bricked my SD Card!

I have bricked my 16G SD card
Anyone any idea how to get the stuff back off the card? I have tried putting it into a Desktop computer but the XP operating system just cant see it in File Explorer
Anyone any ideas?
Pete
Heh... Funny use of the word "bricked".
Originally, it was used to describe a phone that was broken in such a way that it could not be used as anything other than a brick.
Guess that's the way the language evolves..
Anyway, File Explorer can only read the device if the partition is ok.
If you've somehow corrupted the filetable, File Explorer won't see it.
Try this;
Right-click "My Computer"
Select "Manage"
Select "Disk management"
If you can see it as Disk# (where # is a number), you can probably delete the existing partition and create a new one.
Or if you can't see any partition data, just try to create a new one.
Good luck!

whats up bonzo. i got the same problem. my 16gb that came with my hd2 is unreadable and unformatable within my device and cpu. in the disk management screen, i have the sd pluged in and it says that its disk 1 and "31 MB RAW" whatever that means. how would i go about patitioning the data to restore it? i dont care about the files because i backed them up and bought another 16gb. i wanted to see if i can get this unreadable 16gb back up. thanks in advance! just a side note, ive done no physical damage to it, all ive done is add media. the sd came with the phone so it is new. one day when i tried to access a movie and the sd didnt show in file explorer.
If you have a stuffed SD card, try plugging the card into a computer, and run TestDisk and PhotoRec. Hopefully you can get the data off it.
hi,the problem with my sd card is that my touchpro2 can read it but cannot write.I am using energyrom cdma May 23 on the fone.is it possible that having my 2gig transcend card in my fone during my upgrade could ve caused the problm.formatting with my hp laptop get to 90% but then says windows cant complete format.I can still see what I ve on the card but cant remove them or add anything on the card.Any help will be appreciated.thanx u all

Tried this but the computer can see the card as a drive - tried it in an USB stick adaptor and a hub ....no joy
Will try with windows 7 ..... possibly that better
Still stuck and dare not use my phone
PLeeeese ..... anyone any ideas ------ HELP
I'm also having problems with a 16GB SD card in my HTC Hero. My phone is rooted and I'm using the Amon-Ra 1.6.2 Recovery Image.
Booting into recovery mode I go to Partition SDCard, set 0MB for SWAP, 1024MB for EXT2 and the remainder for FAT32. Everything seems to go ok, but having installed some apps on my phone, my internal memory is lower than I would have expected. I've installed Quick System Info Pro and it tells me that it can't get any information for Apps2SD. I'm also having difficulties when copying data to the FAT32 partition, both when the card is in the phone and when it's plugged into a USB port on my computer.
Taking the advice to run testdisk, it reports the following:
Check FAT: unusual media descriptor (0xf0! = 0xf8)
Warning: Incorrect number of heads/cylinder 4 (FAT)! = 255 (HD)
Warning: Incorrect number of sectors per track 16 (FAT)! = 63 (HD)
1 P FAT32 LBS 0 0 2 1915 49 17 30767578
No EXT2, JFS, Reiser Cramfs or XFS Marker
2 P LINUX 1915 49 18 2039 181 62 2000421
2 P LINUX 1915 49 18 2039 181 62 2000421
No Partition is bootable
Can anyone help me decipher this? Am I right in thinking that the three warnings are simply because it's a memory card rather than a hard disk? Also, why is it showing that I've got 2 LINUX partitions?
Does anyone have any suggestions for getting it working? Is it worth making a live linux (Ubuntu?) CD and creating the partitions under that or can I do it while the card is in the phone using adb?
OR, is my SDCard busted?
Windows can't touch to removable (usb pendrive/SD) partition table, you need to use linux for remake it
Also, only one partition, Windows can see only one SD/USB partition

You mean it can only see one pen drive at a time?
he means it wont read more than 1 partition on a single drive, I re-wrote a usb key once for USB booting and somehow messed up the partitions, but HP USB Disk Storage Format Tool seemed to sort it
Well, I've since found a guide on here, written a few years back, to manually create partitions using adb shell and parted, and I've even resorted to downloading Ubuntu and using the LiveCD to boot my PC into Linux and then using the disk tools under that, and I'm STILL having issues.
I can create a FAT32 partition without any problems, the difficulties are coming when I then try to create an EXT2 partition; I get a read/write error.
So, all of this suggests to me that my SDCard is bricked and I need to send it back and get it replaced! Unless of course, anyone has any other suggestions?

are you using gparted in ubuntu? when i created mine for my hero, i had to tick one of the boot optiosn in gparted
also how is it connected to the pc?
Yes, I was using gparted in ubuntu, set to 'master boot record' I think it was. I've got a usb key with an adaptor for the micro sdcard.

keep on messing about with it, Its rare they die unless its been write to over 250,000 times of you have been trying to smoke it
I quit smoking nearly 3 months ago now!
Just to clarify, I create the FAT32 partition first, then the EXT2 partition. Am I right in setting it up with a master boot record (I think that's the option within gparted)?
Regarding the EXT2 partition, do I need to take ownership of it or just leave it for SU access only?
Cheers
may i know which partition you set as boot.?
i've tried to set fat32(boot),ext2,linux-swap still does not work. should i set all partition as boot. is there any limit on the size for ext2 and linux-swap partition?
how you partition the sdcard? connect to pc using usb card adapter or connect to pc using the phone?

[GUIDE][9-JAN] How to partition your SD card correctly for APPS2SD+ ROMS.

It seems many people are having issues partitioning their SD card for use with Apps2SD+ ROMS using the additional EXT4 partition.
Here is a guide to the method that worked for me. I am not responsible for any loss of data on your phone or PC as a result of following this guide. Read the steps clearly and understand them BEFORE you do anything. Failure to understand the steps involved could see you wiping data from your PC's hard drive with no warning messages to tell you what you are about to do. You have been warned!
Firstly, I couldn't get Partition Wizard for Windows to work. If anyone else has been successful with it please let me know and I will update this post.
Before you start, BACK UP all your data from the SD card. It will all be erased from your SD card during this process.
Although this works on a phone which has already been flashed with an APPS2SD+ compatible ROM. I strongly suggest starting with a freshly flashed ROM with no apps installed before doing this to ensure ALL additionally downloaded and installed apps are installed on to the partition, leaving the maximum possible storage space remaining on your phone.
Here are the steps....
1. Download a copy of GPARTED-LIVE from here. Use your favourite CD burning software to burn the image to CD. The image is bootable so make sure you do not leave the CD as open session when you burn it. This is the software we will use to partition the SD card later on.
2. Start with a freshly formatted SD card with a single FAT32 partition. This can be created using whatever tool you prefer. Use the default cluster size setting. I use the Disk Management tool in Windows under Administrative Tools in Control Panel. You can perform this step by inserting the SD into your PC or mounting it on your PC via the phone.
3. Once formatted with a single partition, insert the SD Card into the phone, disconnect the phone from the PC if it is connected. You may find depending on your rom that the card is recognised as damaged. Don't worry.
4. Format the SD card again using your phone. This is done via SETTINGS - SD & PHONE STORAGE. The SD Card should now mount as normal and your phone should report "Preparing SD Card".
DO NOT COPY ANY FILES OVER TO THE SD CARD YET. Android will have copied over its standard files after formatting so do not delete these, but don't add anything else yet.
5. Once the SD card is formatted and prepared, unmount the SD card and remove it from the phone and insert it back into the PC. You may also connect it to the PC via the phone. If you are using the phone to connect it to the PC at this stage I highly recommend booting into MAGLDR and selecting the Mass Storage Mode option to connect it to the computer. This ensures Android will not try and access it while we are partitioning it.
6. With the SD card now recognised by the PC, reboot your PC from the GPARTED-LIVE CD you burned in step 1. This may take a while to load depending on your PC. Follow the on screen prompts until GPARTED loads correctly.
7. With GPARTED now loaded, select your SD card using the selection in the top right hand side of the GPARTED window. Ensure you have selected the correct storage device by ensuring the capacity is reported correctly. BE VERY CAREFUL NOT TO MES WITH YOUR COMPUTERS HAR DRIVE!! If you are not sure at this stage, please do not proceed as you risk wiping data from your PC. GPARTED will not warn you if you are about to damage system files as you might expect it to.
8. Once selected, you should see a single FAT32 partition displayed with a chart which span the top of the window. Click on "Resize/Move" and drag the slider from the RIGHT across to the LEFT to create an area of unallocated space the size you wish to use for your apps. 1GB should be enough in most cases. It is very important to make sure that the FAT32 partition appears IN FRONT of the unallocated space. Once satisfied, click OK.
9. Right click in the unallocated space you created in the chart and click "Create". A new dialog box should appear. Modify the settings so that the partition is set to "ext4". Leave the cluster size set to "default". Click OK.
10. Back in the main GPARTED screen, you should now see two partitions in the chart, the first being your original FAT32 partition and then to the right is your new EXT4 partition. Click "APPLY" and the changes will be made to the SD card. THIS IS IMPORTANT as no changes are made to your SD card until you click apply. If you miss this step, you will have to start over from step 6 again.
11. Once changes are reported as completed, shut down your PC and remove the SD card. Insert it into your phone and boot the phone. If you connected your SD to the PC via MAGLDR, press the power/hang up key to return to the main menu and choose to boot from NAND.
DONE!!!!!!!
Once the phone is booted (may take a little longer than usual) go back to SETTINGS - SD & PHONE STORAGE and you should see your phone's available storage reported as around 20-40MB less than the total storage capacity. This will vary between different ROMS. Don't expect it to read any higher than it did before you did this if you haven't installed any apps yet.
Check to see that your SD storage is reported as the correct size corresponding with the new size of your FAT32 partition.
Now go ahead and install your apps. You will notice that the phone storage capacity does decrease as you install apps, but the next time you reboot, it should jump back up again. That's what happens on my phone anyway.
Once you are satisfied that all is well, you can connect your SD to the PC again and copy across your data to the FAT32 partition.
Another thing to note is that you don't need to format the EXT4 partition when changing ROMS. As it only stores the applications, when booting for the first time with a new APPS2SD+ supported ROM, it will automatically show up with all your apps and widgets installed. Preferences and widgets will need to be reset however.
I hope this guide helps. Thanks again to all the amazing developers here at XDA who make all this possible, as well as the wonderful community of volunteers and members who keep this show running.
reserved for possible updates and additional methods.
First, thank you for ur tutorial.

It'll be easier if you post a screenshot or just a simple pic drawed by MsPaint to see the partition after format.
Thank you anyway.
yes, some screenshots would be very nice. and maybe this thread should be stickie, very useful! thank you for the guide, i will use this as soon as i have a rom with this support.
You have a little misstyped error in step 11..
You insert the card back into phone, not PC
Great guide, gparted is also part of Ubuntu which is what i used!
Cheers
Thanks for the corrections guys. I have amended the original post.
As for screenshots. It's difficult when I am using a separate boot disk. Most things should be pretty self explanatory once you are actually looking at what I'm describing
Thanks for the guide!
However, if I try to create a new partition, the only choices I have is to make it primary or extended. No logical partition as it is greyed out. Does App2SD+ work with a primary ext4?
great guide! wished this was available before i partitioned mine. did a lot of googling before i found an easier alternative.
for those using Clockwork Recovery you can use the Partition SD within Recovery itself. No need to fiddle around with booting gpart and risk wiping your system hdd. the only thing is recovery will create it as ext3 which i don't think matters much because ext4 is backward compatible.
sorry don't mean to rain on your parade because i also use gpart when i'm around a pc. just thought that some ppl might prefer the alternative.

+1 i have a netbook without cd-rom and windows 7...which program i can use to do that?
how to do it on Ubuntu 10.10?
Im guessing that we can use Partition Magic or Paragon.
I will try with paragon partition manager and let you know. It shouldnt be that hard.
I know a screenshot is hard to capture when u're not in Windows, but I offer a picture drawed by MsPaint or Office Word. Just 2 rectangle with the size and the filesystem.
Thank you.

if you're using clockwork recovery boot into recovery -> advance option -> partition sd and follow the steps.
Thanks, I am looking for this kind of instructions from the last 2 days.
I've been using haret since the HD, but I've never owned a native Android phone, and such a fundamental step as partitioning was played lightly over, so thanks for a step for the people like me who do google everything but still couldn't do it correctly. Boot CDs are the only way to do it, it seems.

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...

[q] re-partitioning the glide

i was wondering, when we can get ASOP/AKOP or CM9/10 we can re-partition the glide to have only system partition and the extranal sd card can act as the internal one. we all know that the 8GB is not enough, especially with 2gb system and 6gb sd card - i have 2gb in system and 4gb in sd card - but if we can combine it to full partition then it will be more then enough as a basic install space - cos allot of apps can be moved to sd card and leave little room on the system partition.
It's already possible to change the mount points so that your physical sd card is mounted as /sdcard, and the internal storage takes its place at /sdcard/external_sd. It's a quick vold.fstab edit. You can see my post about it here, with a pre-modified file and a backup of the original.
You'll need root and busybox (or some form of file explorer with root permissions) to copy the file over, but it's pretty straightforward. As for repartitioning the internal storage to be used for /data, I've got no clue how to do that, but this is a reasonable enough workaround.
i know about that workaround but still there some side effects to it, like the usb mounting in the PC.
still i think its doable if creating aosp from source with cross with our ics source from samsung..
maybe a more knowledgeable dev can shed some light on the subject.
Changing the actual partitioning isn't something that's commonly done, as it can wreck compatibility with roms (including official updates) that expect things a certain way. The only issue in ICS with the vold.fstab edit is the internal memory isn't mounted on the phone at boot, you have to manually mount it any time you reboot. MTP file transfers work just fine (with your physical sdcard being labeled Phone and the internal labeled Card) as does the legacy USB Mass Storage mode.
If you really want to mess with it, look into partition editing using parted. This can go very very wrong, and may not work at all, so proceed with caution.
i see thanks for the info

SD Card Problems

Putting this out there because I've never seen this before and cannot find anything on it to fix it.
I have a 64gb microSD card that is formatted FAT32. Been working fine for months and all of the sudden, after trying to copy a zip file onto it yesterday, I no longer have write permissions. I just want to format it and start over but I can't. I've tried formatting it with 4 different programs in windows. I can't write anything to it via usb cable if its mounted in my S3. I can't write anything or delete anything via root explorer. I've tried multiple computers, different adapters in my computer, writing to it anyway that I know how and nothing works. It was never encrypted or anything, just a straight up plain microSD card.
Does anyone know how to remove write protections via a PC or force a format? I've tried to format unsuccessfully multiple times, presumably because it is write protected somehow.
Any help would be greatly appreciated.
Bump.
I've tried to completely repartition multiple times on two different OS's, no luck. Can't get this thing format at all. I can delete a file(s) and create new folders, and it'll show the changes initially, but then if I re-mount it, everything is the same.
When I run a repair program it points to the previously mentioned zip file, saying its corrupt but there is no way that I can see to wipe it. Ideas?
Try fixing permissions and check the first 9 boxes using root explorer.
EDIT: if you are trying to put files over 4GB it will not work.

I tried earlier in the day fixing permissions and it was a no-go. I couldn't do anything through the phone and that's why I just pulled the card and started trying to format/wipe/re-partition the card via computer. It was the same story for both devices though. I could make a change to a file (i.e. delete or move something) but as soon as I remounted the card, it would be like nothing I did ever happened. All the files prior to this happening are there and readable, I just can't create anything new or delete anything.

There's a switch on the side of your SD adapter to toggle read/write

I wish it was that simple. If I put the switch in the locked position, the computer recognizes it as locked. However, if I put it up where it is supposed to be to write to the card, the computer thinks its writable but won't actually erase anything. Same thing is going on when I put the card in my phone and try to manipulate files, without an adapter.
Sounds like the card itself went bad and needs to be replaced.

I tried that a couple of times . At first glance it looks like it's formatted, none of the files show up. However, after rebooting, everything is still there--nothing changed. I just want to wipe this thing but I nothing is taking. I am starting to think that this thing is just done but I am holding out hope because I can still see and read the files that were on there before this fiasco.
Every time I run a repair utility, it points to the zip that caused all of this trouble, saying that it is corrupt but I can't wipe it. I have no idea what to do.

Try the Windows Disk Management
Right click it, and hit delete. Right click the unallocated space and choose Create and format NTFS. Then format it to to FAT32
Click to expand...
Click to collapse
The option to delete the volume is grayed out. Any attempt to format fail. When I run disk repair it does find a problem with the zip file that caused this mess and tells me to run chkdsk to fix it. I do but it never fixes anything.
Is there a program that will forcefully wipe out the partition so that it can be reformatted?
Bump.. Same problem here .Did you find any solution?

Try this:
- Go to start, type in cmd
- Right click on cmd, and select "run as Administrator"
- command line will start w/ Admin privileges
Here, you need to run a program called DiskPart. It helps you "clean" hard drives that have many partitions that aren't normally accessible.
- from cmd line, type diskpart
- a new command line program will start
- here, type "list", it will show you a list of commands.
- type "list disk", find out which disk is your 64GB micro (mine happens to be disk 8)
- type "select disk #" (# is your disk you want for cleaning)
- disk # will be selected.
Very important: Make sure you have the right disk!
- If you are sure, type in the word "clean". This will completely wipe out the disk that was selected.
after that, you're done, you can exit DiskPart/cmd.
Go back to Disk Management, and now you can see that the whole drive is unallocated.
At this point, you can format your drive (using your Android device or Windows, to FAT32 or exFAT)
