Last time I want to bring my photos from SD-card (Sandisk Ultra SDHC 32 GB) to my computer (windows), my computer said that there is no file system on the card and I should format the card. Also my camera can´t read the card anymore.
When I open the format-dialog it said that card has 30,6 MB (not GB).
I do a backup of the card one day before so I lost "only" one day of photography, but unluckily this is the first birthday of my daughter :-(.
I use a Canon 70D and raw-format so file extension is CR2.
So I try some tools to recover, but doesn’t work. In the end I tried testdisk, but also without luck. So here is my procedure with testdisk I tried, maybe you know a better way which can bring my photos back.
testdisk_winsays card has 32 MB (MB not GB).I chose partition table type
none-> No pictures were found.
So I changed geometry based on another 32GB-SD-card
- cylinders changed from 3 to 3905
- heads (255), sectors (63) and sector-size (512) stay without changes
-> Search takes longer, but nothing found.
Is there anything else what I can do before I think about to go to a data-recovery-company?
I think about to format the card and try search again, but I'm not sure I this would bring the final death to the pictures.
