The disk formatting code of Apple DOS 3.1 / 3.2 does something fairly odd: It writes only the sector headers, with no sector bodies. Any particular sector’s body is created the first time that particular sector has data written to it. This means that on such disks it is normal for unused sectors to be “bodyless”
