Deleted files written over each other in Recuva Bug Reporting Posted August 6, 2018 · Report reply Yeah it is formatted ExFat. I didn't find out that the formatted SD had anything we wanted until we had shot about 8GB on top of the newly formatted card. I see that many files were overwritten by post-format files. Those are toast for sure. All I want to recover are those that were not overwritten after the format. The fact that some are showing up as overwritten by pre-format files is what has me confused.
