8.4.1 Defect list Following is the format of the Defect List Header sent during the DATA OUT phase when FmtData is set to one. Bit Byte 7 6 5 4 3 2 1 0 0 Reserved = 0 1 FOV DPRY DCRT STPF=1 IP = 0 DSP= 0 Immed 0 2 (MSB) 3 Defect List Length (LSB) Figure 51. Format of Defect List Header The drive has a limited implementation of the Format Option bits located in Bits 2 through 7 of Byte 1 of the Defect List Header (See Figure 48). If the initiator attempts to select any function not implemented by the drive, the drive terminates the command with CHECK CONDITION Status. The sense key is set to ILLEGAL REQUEST and the additional sense code is set to INVALID FIELD IN PARAMETER LIST. ! FOV (Format Options Valid) bit of zero causes the drive to verify that the setting for the DPRY (Disable Primary), DCRT (Disable Certification), STPF (Stop Format), IP (Initialize Pattern), and DSP (Disable Saving Parameters) bits are zero. If any of these bits are not zero, the drive terminates the command with CHECK CONDITION Status. The sense key is set to ILLEGAL REQUEST and the additional sense code is set to INVALID FIELD IN PARAMETER LIST. Note: When FOV bit is one, three combinations of the DPRY, DCRT, STPF, IP and DSP bits are allowed. Any other combinations return a Check Condition Status With a sense key of ILLEGAL REQUEST and an additional sense code of INVALID FIELD IN PARAMETER List. The supported combination is DPRY=0 DPRY=1 DPRY=0 DCRT=1 DCRT=1 DCRT=0 STPF=1 STPF=1 STPF=1 IP=0 DSP=0 IP=0 DSP=0 IP=0 DSP=0 ! DPRY (Disable Primary) bit set to zero indicates that the drive does not use portions of the medium identified as defective in the primary defect P-LIST for Initiator addressable logical blocks. If the drive cannot locate the P-List or it cannot determine whether a P-List exists, the drive terminates the FORMAT UNIT command as described for STPF=1. A DPRY bit of one indicates that the drive does not use the P-list to identify defective areas of the medium. The P-list is not deleted. ! DCRT (Disable Certification) bit of ZERO indicates that the drive performs a medium certification operation and generates a Certification List (CList) and the drive adds the Clist to the G-List. A DCRT bit of one indicates that the drive does not generate a CList (Certification List) nor perform a certification process while executing the FORMAT UNIT Command. Note: Since the DCRT bit is part of the DATA OUT phase that follows the format command, the FCERT bit in Mode Page 0 is provided to control certification when the format command is issued with no DATA OUT phase. If a format command is issued with a DATA OUT phase then FCERT is ignored. ! STPF (Stop Format) bit must be set to one. If one or both of the following conditions occurs, the drive terminates the Format Unit command with CHECK CONDITION Status. The sense key is set to MEDIUM ERROR and the additional sense code is set to either DEFECT LIST NOT FOUND if the first condition occurred or it is set to DEFECT LIST ERROR if the second condition occurred.
