When the value is 0, the returned data does not include the Primary Defect List.

When the value is 1, the returned data&GUETKRVKQPincludes the Primary Defect List. The defects

 

 

are returned in ascending order.

 

 

 

 

 

 

When the value is 0, the returned data does not include the Grown Defect List.

 

 

When the value is 1, the returned data includes the Grown Defect List. The defects

GList

 

are returned in order of occurrence.

 

When both PList and GList are set to 1, the Primary Defect List and the Grown Defect

 

 

 

 

List are returned. The Plist is returned followed by the Glist (the lists are not merged).

 

 

When both are set to 0, only the Defect List Header (Table 5-138)is reported to the

 

 

initiator.

 

 

 

 

Defect List

 

This field specifies the format in which the defect descriptors are to be returned. The

Format

 

supported formats are:

 

 

 

 

 

 

 

000b

Block Format (Table 5-136).￿

 

 

 

 

 

 

 

Bytes from the Index (Figure 5-63). The data re-

 

 

100b

turned from this mode does not include defects

 

 

 

outside normal user space.

 

 

 

 

Table5-135

101b

Physical Sector Format (Table 5-137). Default for-

mat. The defects returned from this mode do not

 

 

 

include defects outside normal user space.

 

 

 

 

 

 

 

Vendor-Unique Format. This format is valid only

 

 

 

for the READ DEFECT DATA commands. The data

 

 

110b

returned from this mode does not include defects

 

 

 

outside normal user space. Note that the vendor-

 

 

 

unique format is proprietary in nature and thus is

 

 

 

not documented in this Product Manual.

 

 

 

 

1All in-line spared blocks do not have an associated LBA, and, therefore, will not be seen in Logical Block Format.
