So, I have recently discovered an issue where by if I copy files directly off the SD card with it inserted into my computer that they are not right (see attached). If I copy them off the SD card with it in the camera, they are fine and can be viewed on the PC without any issues. I can live with that for now.
Recently I took some photos and not knowing about the above issue did a cut and paste onto my computer where I found I had this issue. Straight away I took an image of the SD card and have put it aside. I have restored the image to other SD cards to see if any of the recovery software can help me but they all have issues. Just to be clear they can all recover the files but this is with the SD card plugged into my computer which has the same issue as above. I can't find any software which will undelete the files on the SD card (which is different from recovering them to a different location). The other option would be software that can see the SD card while it is plugged into the camera. When I plug the camera into my computer I can see it as a device (not a drive) and I am yet to see any recovery software that can connect to it.
Not to confuse the issue but when I open the folder the files are in and change to view as icons they initially appear correctly but shortly after change as per the picture. About every 7th photo is fine and some are worse than others. The photos below are the worst ones.
Any help would be greatly appreciated.
