I have recently used an sdhc card (64GB) to backup computer data. Before formatting, I saved around 40 GB of photos to the card. After formatting, I could only retrieve 7GB of data from the SD Card. The rest of folders are empty. I had formatted it as exFat , so I thought it would not be an issue to store that amount of data. When I go to properties I see 40GB used, but, in reality there's only 7GB.
What happened with the photos? Is it a problem with the format, or, capacity? I've tried some recovery software with no success.
