Thanks for the suggestion. I think Sony uses the full format. I guess there's not much I can do then.
Thanks for the heads up. I transferred all the files but in small format to my phone so it's not all bleak. Unfortunately, the full files are gone forever it seems. I guess I have to be more careful next time.
If these are truly priceless, say of a relative that would soon be deceased, and you are saving it for future generations, as an absolute last-shot measure, seal the card in a air-tight container, label it with the contents, and put it away in a safe-deposit box with as much information as possible about the camera, the card, how it was formatted, etc.
Been there. Try Transcend's RecoverRx.
Maybe in 10 years. In a half century, nobody will know what an SD card is and all the SD card readers will have become landfill.
Last year I tested a lot of the well known photo recovery applications, most appeared to recover the images, but when I viewed them or loaded them into my RAW processor, they were all corrupt.
Oh, I know what a 5.25" square Low Density Floppy Disk is, and it's been 34 years.
Still got a working drive?
Still know who does, and I'm sure there will be specialized IT shops in 2070 that will have BDR drives.
Unfortunately (in such situation) Sony is using correct way of formatting SD cards - it is not simply erasing the filesystem structures but is doing "Erase" command on all sectors - which resets the SD built-in wear leveling system, marking all sectors as available. The bad side of the is that this operation breaks links between logical sectors presented to camera with physical sectors on the SD card. So even content-aware scanning software will simply read all zeros or random contests (depending on SD card controller implementation). Of course the content is still physically on the card but there is no way to read it using card's interface.
