All,
I have a trail-cam with a 16G card that I use to monitor the predators coming into the yard so I can keep the cats from getting eaten (long story). This month when I pulled the card, it can't be recognized in any of my readers (Linux or the kids Windows boxes) It is seen and the full 16G is recognized, but blkid reports no filesystem on it. No clue what happened, lightning, low-battery, who knows.
But now that leaves me with the problem of how best to try and recover what I can. Do I just image all 16G with dd_rescue and then use a scanner that will recognize the jpeg headers and try a recovery that way. What tool?
Not dd-rescue, there is no benefit by trying to read multiple times. Just plain dd. Then run the scan on the image with photorec - which I see you already used.
Update:
I have run testdisk and photorec against the card and absolutely nothing is found. I made two-passes with photorec, the first looking for all file types, the second looking only for jpg files. Nothing was found at all. So I guess this card is just toast.
Gah... :-( Google "photo card recovery" suggests: https://www.cnet.com/how-to/how-to-recover-deleted-photos-from-a-memory-card... But that thing works similarly to photorec. If there is no data, it will not work. If I google for "sd card recovery" instead, I get: https://www.easeus.com/data-recovery/sd-card-data-recovery-software.html which is more promising. I remember reading a name similar to "F3" but I find nothing, probably got the name wrong. -- Cheers / Saludos, Carlos E. R. (from 15.1 x86_64 at Telcontar)
