You had formatted the volume and created new volume with NTFS file system. You can scan the new volume as FAT such that all files will be found during scanning process. Also, if before formatting the volume the file system was FAT and you selected scanning as NTFS then scanning process still finds data from that volume.

However, you cannot select region from a volume while performing raw recovery on the volume.
A long list of file types is provided in the raw recovery file type option. You can add file type, if the required file type is not listed in the file type list.
