The defect list is optional for this command.  If the number of defects in the 
defect list is 0, a format device command with no defects is sent to the 
controller.  If the field is nonzero, the defect list is sent to the controller.  
The defect list is re-formatted by the SCSI firmware, if necessary, to the format 
required by the controller.  
Assign Alternate Sector Packet (SCSI)
The SCSI command sent to the controller is:  Assign alternate block ($07).  
A size error status is returned if there is not at least one entry in the defect list.  
The defect list used is the user list, but with a byte count added in the second 
word by the SCSI firmware.  
The first table is the details of a format/assign alternate sector packet.  The 
second table is the related defect list.
