Hi Guys

This is my problem :

my SD CARD, 8GB .. 5 months ago, it become RAW, so there where I found out about Testdisk, it fix it.

Last week, same problem appeared, I tried TestDisk .. but nothing happened, after many times, I tried , this option in testdisk 7.0 -----> MBR code..... then It was fixed , and I was able to see my files .

however I just couldn't access to one particular folder, so I used CHKDSK, it deleted the whole folder icon_eek.gif

then after a day , THE SD CARD, went RAW again.... I tried again TestDisk, it says that the CHS and LBA don't match , I tried again MBR code, but nothing happened,

So I thought maybe if I format it with ( My computer --> management ---> Disk Management ) I could recover my files .. so I format it with FAT32 .

Now I tried more than 20 software, none of them could recover a single file.

and this what I see in Testdisk :

 

Attached File  1111.jpg   213.72KB   0 downloads

 

and also It said , NONE partition table has been detected o_O

Attached File  2222.jpg   83.44KB   0 downloads

 

and this is the lost one .. called ( NO NAME )

Attached File  0333.jpg   64.52KB   0 downloads

 

but this is what happend after I continue

Attached File  4444.jpg   61.99KB   0 downloads

 

Please help me ... I really need this SD card, more than anything, it contain all my studies files, my PHD dissertations, it's my life, and am really hopeless .

It least a way I could recover the RAW .. as it was before I format it.
Thank you

You formatted the drive .. wiped it ... it's clean .. no data. ( no recovery ) And if I havn't been clear enough heres some more people to tell you.

Sorry, but if you formatted your SD card I believe there is little chance of recovery. Once the SD card went bad and you recovered with Testdisk the files should have been backed up that is then and there.

 

When you highlight each of the FAT32 partitions and press the "P" key do you see your files.

 

If not your only chance now is to scan the SD card with software like Easeus Data Recovery or use PhotoRec which is included with Testdisk.

 

 

If you cannot recover them then you need to send the card to a professional data recover service which is expensive. There is a person on the board from Data Medics but I do not know if they do SD card recovery. Edit: And after a format I doubt they would be able to help but you can always contact them.

I guess you didn't learn from your mistake:

 

1. Always have a backup

2. At the first hiccup, make another backup

3. Stop using the device if you have any doubts

4. If you don't know what you're doing, don't!!

 

Now that, that's out of the way.  If no data recovery software is reading the card, ti's almost certainly failed.  SD cards can often cost even more than HDDs to recover, and it likely may not even be possible.  If your data is worth more than a few hundred $$$ shoot me a PM and I can recommend an affordable company overseas that may be able to do it at a reasonable price.

It does appear that the card is still showing it's capacity, which is actually a good thing.  I'd recommend that you download a free trial of R-Studio, then first create an image of the card to a file.  Then scan the file (not the card) using R-Studio to see if it locates a filesystem.  If it doesn't, check in hex to see if the data actually looks like data, or if it's all just 00 00 00 00 or another repeating character which could indicate that the memory isn't being read by the controller.

If this image was made before the SD became corrupted download OSFmount here. Run it and open the dd file. OSFmount wll let you mount the image as a virtual drive. Copy your files from the virtual drive to your hard drive.

I think the only choice you have now is to run PhotoRec on the dd image using the command line. To make it easier you could copy the Testdisk folder you unzipped to the root of C:\  Type CMD in the search box of Windows 7. This would give you a command prompt of C:\Users\<your name> then type

 

cd C:\

cd <the test disk folder name>  You should now be in the Testdisk folder.

 

To recover files from a media image, type the following at the command prompt

 

photorec_win <your image name>.dd    Edit: Changed from photorec to photorec_win

 

to carve a raw disk image .This will recover any files it finds to the Testdisk folder.

Hi, sorry I disappeared on you.  Have been swamped in work and not paying much attention to the forums lately.  What does the data in the image look like in hex?  Does it look like actual random data, or does it just look like repeating characters?
