GetDataBack for FAT/GetDataBack for NTFS
GetDataBack Data Recovery is a highly advanced data recovery software that will help you get your data back when your drive's partition table, boot record, or FAT/MFT or root directory is corrupt, a virus has hit the drive; when files are deleted; or when the drive is struck by a power failure. The software can even recover your data when the drive is no longer recognized by the operating system or when all directory information is lost. Advanced algorithms will make sure all directories and subdirectories are put together as they were, and that long filenames are reconstructed correctly. GetDataBack Data Recovery is safe because it's read-only, which means the program will never attempt to write to the drive you are about to recover.
