Data Recovery and Disk Utilities Forum @R-TT

Hi Guys,

I am new to data recovery and R-Studio, please bare with me. I have a SD card from an action camera that does not work. When I connect the SD card to computer it says:

You need to format the disk in drive D: before you can use it

and when I click cancel it says:

the volume does not contain a recognized file system.
Please make sure that all required file system drivers are loaded and that the volume is not corrupted

I installed R-studio Demo to see if I can recover the files. I have created an image, during which I received many error messages:

Sector 122893309 failed to read from after 2 attempts. A device which does not exist was specified (433)

Error messages continues from Sector 122893309 to 122894303. I then scanned the image, ticking all file systems and extra search more known file types, to which the scan comes back with an image of all the partitions being unprocessed.

I am not sure what I can do at this point to try and recover the data. If anyone can, please help

1. Save the scan info to not rescan the device again.
2. Was sector 122894303 the last one on the SD card? If not, did R-Studio continue disk scan after this sector?
3. I couldn't understand this part of your sentence: "to which the scan comes back with an image of all the partitions being unprocessed". Did R-Studio show you some recognized file systems? And if yes, did you browse through the found partitions?

Thank you for your reply!

1. Done
2. Sector 122894335 was the last, R-Studio continued, and an image was successfully created. I have since been scanning off the image.

Looks like there are some hardware problems with the card, or it was fully wiped out.

Thank you for your help, is there anything more that I can do to recover the data?

Edit: it also seems like
sector 1 - 92 893 695's binary is "FF"
sector 92 893 696 - 122 894 303 is "E5"
sector 122 894 304 - 122 894 335 is "00"

What happened to this card?

The (micro) SD card was used in a Faux GoPro on holiday (August this year). After the holiday (14/08) the card was used via wifi to download images, and message came up saying "Card Read Failed".

The card + camera set was purchased together in June last year, it was used in a few holiday trips prior. All being fine. It has been kept inside a protective case, no dirt or water has entered when it was used underwater.

After the wifi download failed it was tested on a laptop and could not be read either.

I have checked the physical card there does not seem to be any scratches or bends.

I have updated last post with additional info:
sector 1 - 92 893 695's binary is "FF"
sector 92 893 696 - 122 894 303 is "E5"
sector 122 894 304 - 122 894 335 is "00"
122 894 335 being last sector

Disk manager also shows it to be RAW files.

Hope this is helpful

Looks like all data was overwritten. Nothing can be done in this case.
Or, possible, some strange failure of SD hardware, but this is for a experienced data recovery pro.
