Read Defect Data (B7) - Fujitsu MAX3073NC - SCSI,80, Dell DC961,Hard Drive Scsi Logical Interface Specifications

Command Specifications
7. In defect data in the block address format, all the physical defect position information on the
disk media cannot be described universally. For example, defect position information in areas
without block addresses (spare sectors, or cylinders which are not being used as User Space or
CE Space) cannot be described. The defect data in this format are provided in order to preserve
continuity with previous specifications, but it is recommended that as much as possible, the INIT
not use the "Block Address Format."
