If you have problems with your memory card in 80% of all cases the controller of your card is damaged and no software or card reader can help. You must separate the memory chip and dump the raw data to recover your data, look here: CF xD SD memory card/stick photo recovery
Repairing a corrupted SD card.
If the SD card is corrupted then it will be because it has boot sector errors. Download DriveRestore Professional and you can scan your corrupted card for errors... you can then repair the card's errors when the product is activated. You can download a free trial at: www.pcrecovery.com/driverestore
don t format in the name of GOD!!!
Please all keep in mind>>>> drive recovery pro is a nice solution,but formatting a hard drive is ok,and important.NOT A SD CARD!!!The continous files are different from the usual hard drive files!!
NO NEED FORMATTING!!!
In fact>>formatting an SD card lower the life time of the card with a good year or more!!Anyhow they made to survive only around two years!!!
The continous upload and erase sssions are killing the SD card.BUT FORMATTING IS TH BIGGEST KILLER.Check the experts,what they say???
Corrupted cards can be deffected from factory as wel,but drive check and restore is the best.The sectors are damaged,and not the fragmantation....

Repairing a corrupted SD card.
DriveRestore Professional will not re-format a corrupted SD card. Formatting is NOT recommended as formatting will erase all the data on the SD card. DriveRestore Professional will analyse the boot sector (that ALL drives have e.g. FAT16 and FAT32 file systems on an SD card), it will detect errors in the boot sector and then repair the errors. When the card is repaired, ALL the files will be accessible and the card is fully repaired.
Sometimes the filesystem on the card gets corrupted. It can happen for example if the card was ejected while a file operation on it was in progress. When that happens you might have trouble accessing some of the files, loading times for some directories in file explorer may be very slow.
You can attempt to fix it using the desktop windows' built-in chkdsk utility.
Open up command prompt (start->run->cmd.exe) and type
chkdsk /X /F <SD card drive letter>
My SD card reader is X:\ drive, so i wold use the following command:
chkdsk /X /F X:
SD card reader is recommended, but probably not necessary because it should also work with WinMo's built-in USB mass storage function or wm5torage.
Under linux you can check/fix the card's filesysterm and in some cases undelete a file using fsck.vfat or dosfsck (single tool, two possible names). Refer to its help for more details.

I only recently became a (sort of) expert on this as I had a corrupted NTFS bootable partition on my macbook pro with a messed up Master File Table. Man, that was a nightmare.
Anyway, the answer to this question varies greatly depending on the filesystem and the type of corruption you have. Standard Chkdsk might work (the windows utility) although I admit I have no idea how well that works on flash removable media.
Other good options are TestDisk, and there are some other free options out there.
Depending on how important your data is to you and how severe the corruption is you may need to go with a paid application. This is what I had to do because Master File Table corruptions in NTFS are particularly nasty (although some versions of them can be corrected by TestDisk). I recommend GetDataBack which worked great for me.
In any case, try TestDisk out because its a very powerful tool and it is totally free. Read up on the documentation before playing around with it though, because you can cause irreparable damage to any one of your disks if you don't know what you are doing. Ideally make an image of your card using dd (built in linux utility, just type 'man dd' at the cmd line) before attempting to fix it so you can't do anything you can't undo.
hey i formatted my card using card studio in qtek 9100 it formatted 100 % but when i attached it on the card reader then to PC! PC doesn't show this cardddddd help meeee
Instructions
things you'll need:
* SD Card
* Computer
* Internet Connection
*1
If your aim is to repair a corrupted SD card so that you can use it to store files then proceed to step #2.
If your aim is to recover the files on the SD card without erasing them, proceed to step #5.
*2
Insert the SD card into a digital camera card slot and choose to format your card. If this doesn't work then move on to the next step...
*3
Place the SD card into your computers SD card slot.
Right click on the SD card drive letter IF it appears and choose to "format."
If this doesn't work, proceed to the next step...
*4
www.sdcard.org
You will need to go to the website
http://www.sdcard.org/consumers/formatter/eula/
Here you will download, install, and run the program to format your SD card. This is the most advanced step of the three, but most likely to work 99% of the time.
*5
www.cgsecurity.org
If you want to recover files ON your SD without erasing them, then you need to download and run the software on this site.
http://www.cgsecurity.org/wiki/TestDisk_Download
This is the best free software available for this type of problem.
thanks mr deimos for the chkdsk tip.this tip is way quicker fix than the programs mentioned in other posts in this thread
yeah, thanks guys for all your advice and help

Thank you for this, saved my uSD card after flashing a kernel messed it up!
On Linux you can try dd_rescue. It creates copy like normal dd but it does not abort on errors.
Copy card to file and then mount this file like drive
Thanks for the chkdsk /X /F
I just had a currupted sd card this morning and was banging my head until I saw this and it fixed it.
THANK YOU!!!!!!!!!!!!!!!!!!!
Hi
I have a problem with my orbit 2.
I connected it via activesync.....and when I went to expolre my windows mobile dased device the folder storage card was COMPLETELY EMPTY !!! omg.......my garmin map is gone all my pics and mp3 etc...
It is wierd, however when i click on properties it says that 1,5GB of 8GB is already taken up?
Any ideas please???
I had the same problem.I think if you hard reset your device and you have encryption enabled you cant see the files on your card but there still there.Windows wouldn't let me format the card so i used Pocket Mechanic http://www.wizcode.com/products/view/pocket_mechanic_professional
but doesn't format erase all the data on the card?what procedure would u suggest to get back the files? btw i don't recall my device recently hard resetting.

It's a common problem on all Windows based OS (including WM).
It caused by Corrupted Filesystem & usually occured on FAT based File System.
FAT based File System (FAT / FAT12, FAT16 & FAT32) is commonly used on Removable Storage including Micro SDHC.
Windows Based OS can cause this Corrupted Clusters / Chained Cluster problem when it failed to close one or many opened files properly.
The failure can occurred due to unstable application (hang) & turning off the device is the only solution.
But,by turning off the device,another problem may occured (Chained / Corrupted Clusters).
Basically almost all of your files are still intact.
To solve the problem :
Turn off your device
Remove your SDHC
Use a SDHC card reader & check for errors using CHKDSK
Press Win+R & when Run dialog box appears type cmd
When Command Prompt window appears type :
chkdsk /f /x <drive_letter>:
Change <drive_letter> with the location of your SDHC.
e.g : chkdsk /f /x f:
I hope this can solve your problem

I agree, I've had the problem with my first WM device (Medion PNA100) and my XDA MiniS and Orbit1 (there was a fix for the Orbit1(Artemis)).
I think it's something to do with write back cacheing and it can happen with other OS's too.
My stepson just trashed an 8GB sandish ultra SDHC by taking it out of the card reader in his PC and putting it back in his Samsung Tocco.
Try CHKDSK and you *might* be lucky, the files are still there it's the FAT that's f*!%$d :x

You can also try more "heavy artillery" approach, using card reader and some of data restoring programs.
They work with HDD's, but most of them works with all R/W magnetic media (floppy, HDD, memory cards).
Here is example of such software: EASEUS Data Recovery Software
Thanks for your advice.......however when i run chkdsk it asks me if i want to convert chains to files?......what should i do?
and should chkdsk give any sort of summary if it found some mistakes?......what is the part of the "report" that i have to pay attention to?

My guess is that only the pics on the card are irreplaceable, if you allow chkdsk to convert lost chains then they will effectively be lost (as pics).
It might be best to try to recover them with data recovery sofware as Bodisson suggests, everything else like the maps presumably you have the originals.
Hi
As chkdsk, didn't do me any good, I used two different data recovery programs. (PC inspector and Zero assumption).....i managed to retrieve most of my pics and video clips.....everything else was unfortunately lost.....I now formatted the card and reinstalled the maps etc.
Yesterday, I dumped the whole internal memory of my phone into the SD Card by using the command:
#dd if=/dev/block/mmcblk0 of=/storage/sdcard1/dump.img
Next day, when I rebooted the phone, I was greeted with the message "SD Card is damaged. Try reformatting it." When I pressed format, it showed "Erasing SD Card" and after sometime the message appeared again.
So, I brought out the SD Card and put into my computer (by inserting it into a dongle; as I don't have an adapter). Astonishingly, I could read all data of the SD Card, but couldn't write to it. Any file I place there, disappears after refreshing. When I tried to format the card, a window appeared saying "Windows cannot format this device".
So, I googled a bit about these and did the following things:
1. Used a third-party formatting software (SDFormatter by SD Association) : It says that the USB is write protected.
2. Checked the SD card for any physical write protection switch : There was none.
3. Ran the disk management by right clicking "My Computer" > Manage : It gives the same error that the disk cannot be formatted.
3. Tried to delete the volume and create a new simple volume from disk management : The "Delete Volume" button is not clickable
4. Used the diskpart utility to create a new partition by the command "CREATE PARTITION PRIMARY" : It does not work. It says that "No usable free extent could be found. It could be that ....." etc.
5. Tried to clear read-only mode by using "attributes disk clear readonly" from diskpart : Even after that the disk is not writable
6. Tried to use chkdsk from command prompt : It gives an error in the middle everytime saying that "/dump.img is a false link" and after that the disk becomes non-readable and chkdsk crashes, saying that the source files could not be read.
So, please help me. The card was not physically damaged in any way, so it must be possible to bring it back to its original state. Any help is appreciated.
Additional information:
My SD Card: Sandisk 16 GB microSDHC
My Phone: Panasonic P55 , Android 4.4.2 Kitkat
My Computer: Windows 7 & PCLinuxOS
Thanks in advance.
I was reorganizing files on my computer and sd card. For this i had to delete lots of stuff, etc. MTP was being slow so i decided to remove the micro sd card and use a card reader instead to speed things up.
Something screwed up real bad. Now the card is locked. When i plug in the card reader i can see and read the files, i can delete them, delete everything, but when i plug in the card back again - as if nothing happened.
The native format from windows explorer fails to start. It reports an error: The device, \Device\Harddisk5\DR20, has a bad block.
The diskpart utility fails as well with an error: Cannot zero sectors on disk \\?\PhysicalDrive3. Error code: [email protected]
SD Memory Card Formatter from sdcard org - this program succeeds in format without errors, but when i unplug in insert card - everything is the same
The Disk Wipe - Portable v1.7 program succeeds in format, but again - when reinsert the card - everything is back as it were.
When i reinsert the card in the phone, the phone will initiate a 'check for errors', take a lot of time, won't report any errors found and eventually the thing says card is mounted. But when i attempt to access it - the File Manager hangs and needs to close. If i try to unmount the card, the process take a lot of time so i just unplug it.
What can be done? Never had problems with this card, this thing occurred just now. It's unbelievable.
EDIT: Disk Wipe failed as well - said all NTFS boot sectors unwriteable.
Same here!

I have this exact same problem. 8Gb SD Card on Card reader, something went worng, now the files that are there, never change. I can't put new files, if I delete old ones they come back after un-plug and plug-in again.
I was able to make "something" happen, after a while, I reformatted it in exFAT and then again to FAT32. The Old drive name did change to the new one I've selected, and the files are gone, but now it's completely empty it says all the space 7,50 Gb is free, but I can't access it, nor can I clean the partition table using Diskpart, I get Access Denied (as admin and readonly=no) error and on Event Viewer I get error [email protected]
Anyone? Please? Save our Flash drives? Thanks.
I know this thread is old but it's the first result on Google when searching for the error code, so I'm posting my reply. Someone on Spiceworks linked to this tool. It formatted my broken SD card that had this exact issue, and now I can use the card again like normal.
Hello!
My 128 GB SD card (Sandisk) had corrupted files. Every time I delete files, they appear again. I even tried to quick-format the card on Windows, but the files appear again. I also formated it without quick-format which took about 24 hours and the files were again on the card.
Is there a tool that could delete everything? A partition manager maybe?
Is there a way to find logs of what is happening exactly to that SD card? The card is 17 months old.
Thank you!

Ok, but does Android give it a new partition and file format?
Ok, I formatted it from Android within, but there are no changes. All files are still there again.
Is there a write protection on my SD card?

Have you tried running chkdisk on it yet?
If it were write protected, it would prompt you when you went to format it in Windows.

Use this tool in your PC and format sd card in FAT32 format.
@Droidriven: I deleted the partition, but was unable to create a new one. As a result, I was unable to format it again and Windows does not assign any drive letter. Thus, I was unable to use chkdsk. However, Android still recognizes the card, but I cannot make any changes to it. Even when I format it again on Android 7, it says "format succesfull!", but the old data is still there.
@ Ashwinrg: Thank you! But now Windows does not even recognize the card because of the reason I mentioned above.
Update: I manually assigned a drive letter, started CHKDSK, but it says that during "examining the map bits of the volumen" ("el mapa de bit del volumen" in Spanish) errors have been found, but the lost archives cannot be recovered.

To fix the errors
chkdsk X: /f
Where X is the SD assigned letter
To recover some deleted files or files that you couldn't move from SD card you should have used programs like : testdisk or photorec to restore them before you did a format.
@-Hope-: CHKDSK does not work because it throws some error messages.
How do I know if the card lost its abbility to write data? All I can do is read data. I don't want to recover data. I just want to fix the card.

Hello
Seems that the SD is write protected
We can try to disable the protection using diskpart tool in windows
Connect the SD card -via card reader is a recommended step- or if your laptop have a buildin reader
Open a CMD (admin)
Type diskpart then enter
Type list disk then enter
You will see a list of disks and partitions etc..
Type select disk <number of the disk> for example
select disk 2 then enter
Type then
attributes disk clear readonly and enter
Then type exit and enter
The method is explained here with pics on wikihow
http://www.wikihow.com/Disable-Write-Protection
There are some other methods you may try too

Unfortunately, I think after all of this, your card might be too corrupted to repair/reclaim. You might be chasing your own tail with this but I guess it is worth continuing to try.

I already contacted the manufacturer Sandisk which offered me a free RMA. It seems that the SD card is physically broken.
THANK YOU ALL FOR YOUR HELP!
