_____________________________________________________________________________________
The defect list shown in Table 5.2.1-5b contains a four byte header followed by one or more defect descrip-
tors (Table 5.2.1-6d). The Defect List Length in each table specifies the total length in bytes of the defect
descriptors that follow. In Table 5.2.1-5b the Defect List Length is equal to eight times the number of defect
descriptors.

Function
Drive defect List Header Bit Interpretations
[1] FOV
If one, the disc drive interprets the DPRY, DCRT, IP, STPF and DSP bits. If zero, the disc drive
checks the DPRY, DCRT, IP, STPF and DSP bits for zeros.
[2] DPRY If one, flaws in the disc drive P list are not reallocated during formatting. This means existing
reallocations of the P list are canceled and no new reallocations made during formatting. The P
list is retained.
If zero, flaws in the disc drive P list are reallocated during formatting. A Check Condition is sent
in the status if the P list cannot be found by the disc drive.
[3] DCRT If one, the disc drive does not perform a verify function during formatting (thus no C list for this
format is created or reallocated).
If zero, the disc drive performs a verify function during formatting and reallocates any sector that
fails the verify (i.e.; a C list is created and these flaws reallocated).
[4] STPF
If one, formatting is terminated with a CHECK CONDITION STATUS if an error is encountered
while accessing either the P or G defect list. The Sense key is set to MEDIUM ERROR and the
additional sense code shall be set to either DEFECT LIST NOT FOUND or DEFECT LIST ER-
ROR.
If zero, formatting is not terminated if an error is encountered while accessing either the P or G
defect list.
