Image recovery from SD card

Hi All
Hope someone can help em with this one? I had a card error whilst shooting with my K5. Media recovery software was able to find all the files but the raw files were named "~MGP xxxx" where they would usually be labelled "IMGP xxxx".. The file sizes are about right but if Photoshop Elements is asked to open the image file is reports it as an unrecognised document.

I have tried to rename the file under windows but it simply reverts to the version with the "~" as the first character.

Anyone have any ideas or experience of this happening. I do always fromat my memory cards in the camera and tend to repeat each time I copy the images to the PC as one way to have a "clean" card the next time the camera is used.

Thanks, Geoff

I had a hard drive failure about two years ago. Recovered nearly all jpegs as readable files (with some slight re-naming issues) but raw files were corrupted/damaged beyond repair- no way could I get them open- tried PSE, Gimp and even grown up photoshop.
This is one reason for back ups!

Could be that the actual problem is that the file type is corrupted. Try right-clicking one of the files, and if you are offered up a dialog box which says something along the lines of "OPEN WITH", try opening with MS PAINT. If it opens the file, click FILE/SAVE/SAVE AS and save as a JPG/JPEG file. I'm guessing that you will have lost the metadata contained within the files that allows them to open as RAW files. Let me know how you get on.

Hi,
Try this freebie, it's always worked great at recovering jpegs and will find anything on the card that has been deleted but yet to be overwritten.

Once you have recovered all files make sure to re-format the card.

Good luck

Thanks for this. I did try the right click and none of the options, including MSPaint, will produce anything except to see it as a approx 30 MB file.

I will try that recovery software as I still have the camera card in safe storage. The files are all of the DNG type.

At least we can see that some recovery is possible - unlike if you had an issue with roll film...

Going right back to the old days, if a file was deleted the OS (Dos or Windows) just replaced the first character of the filename with "~" rather than actually deleting the file data (which is why files can often be recovered). The OS thinks any filename in the FAT starting with "~" has been deleted and will not use it.

File recovery software should have a good chance of getting the files back.

I thought it was actually a '?' instead of a '~'. Might be mistaken though.

If the memory card is not recognized in the PC or it is impossible to access the data on it, the controller on the card is damaged. There is only one way to get the data back, digital media recovery and directly access their raw data with a programmable digital media recovery tool. You can use Recover Data for Digital Media Recovery Software
