The packet points to the defect list. The defect list contains defect sector numbers in ascending order. Following the defect list, an "additional" work area must be provided. This work area must be equal to 2N + 1 longword, (where N = number of defects). Some controllers require the defect lists in a different form, and if needed, the SCSI firmware builds the list in the area provided. A defect list code of $0000 implies that the defects are specified as physical sector numbers. Otherwise, the defect list codes and their corresponding representation are as follows:
Code $0000 = Sector number
Code $0001 = Cylinder, head, sector number Code $0002 = Cylinder, head, bytes from index
