The bad devices is a 2 week young Samsung EVO 64GB which I wanted to backup the first time... There are important photos (~200 taken with a Nikon) for my work and I'm shocked that this Samsung "quality" product is such a disaster.
For some reason the SD card gets only recognized with 7791MB out of 64GB it does have. And I have the impression that this is the reason why I don't have success with Photorec recovery software. I can't format and can't recover..
Any help is much appreciated!
What I tried till now:
Wondershare RecoverIt, Disk-Recover, Recuva etc
Tested different PCs and SD reader slots
I did a quick format with Win as it was recommend for a Wondershare tutorial...
5-6 passes with Photorec with 0 results
3-4 passes with Testdisc
Advanced -> type -> Fat32
Deeper search -> no success
Its from reputable Seller and/or directly from Amazon. The speed test I made were amazing and better then the specs indicate, so I guess this was genuine Samsung "Quality".
I did contact the warranty department. Still looking for a solution. This is a terrible experience not being able to backup the data once. I'm gonna stay away from Samsung memory cards from now on as this happen to me with a Samsung card before years ago...
