The Fast Imager is designed to quickly image unprotected floppy disks and to recover data from damaged, unprotected disks. It displays its progress and highlights bad sectors. Bad sectors can be retried multiple times in hopes of getting a clean image. | The Fast Imager is designed to quickly image unprotected floppy disks and to recover data from damaged, unprotected disks.
