So, I've never seen (or heard of) a card do this before. It is a 32gb Netac microsd card, formatted FAT32....it contains many GBs of photos on it. Suddenly one day it turned itself into a 2GB card, formatted FAT16. It appears to be completely healthy, no errors or anything...and it has a completely valid (but completely empty) FAT16 filesystem on there. I've tried to recover images from it using photorec but the 2gb which is readable is completely empty. The device the card was in (a camera) does not even have the ability to reformat a card to be FAT16 - it is FAT32 only. The firmware on the card itself seems to be reporting that it's a 2GB card - I can't even reformat it back to the 32GB size - all utilities (dd, ddrescue, various other imaging apps) recognize it as 2gb capacity, and will not read the full 32gb. I purchased the card as part of a 3-pack of cards, and I've tested the other 2 cards it came with and they are legitimate 32gb cards (not sketchy counterfeit cards or anything, from what I can tell). I'm at a loss....anyone have any ideas of how to read the full 32gb off the card? Thx

Please consult a professional recovery lab, do not use SD cards as a long-term storage facility and consider buying quality storage instead.

Ok, thanks. FYI I wasn't using it as long-term storage - it's about 8 months old and was being actively used in a camera.
