Dump list of my notebook's 8GB HDD. Original Disk Record (ODR) means MBR and Extended Disk Record (EDR) means extended partition. Asterisk means Extended Disk Table (EDT), which points next EDR. EDR contains a secondary partition and/or more EDT. Thus, secondary partitions are stored in "linked-list", and they can exist till exausts disk space. ODR, EDR, and EDT are new terms proposed by me (I'll discuss later).
