Unused MO disks come with a disk drive and cable as a bonus. The disk drive does not have a power adapter, so its functionality has not been confirmed and is offered as a bonus. The disks are new and unopened, but they are old, so the packaging may be dirty. Also, for packaging reasons, the outer packaging of the 5-disk multi-packs may be removed. TEIJIN 640MB x 6 disks (Mac format) MITSUBISHI 230MB x 20 disks (Windows format) ※One 230MB disk was found, so the total has been changed from 19 to 20. Thank you for looking.
