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 5-144)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 5-142).

 

 

 

100b

Bytes from the Index (Table 5-143). The data returned from this

 

 

 

 

mode does not include defects outside normal user space.

 

 

 

 

 

 

 

 

101b

Physical Sector Format (Table 5-143). Default format. The de-

 

 

 

fects returned from this mode do not include defects outside

 

 

Table5-141

 

 

normal user space.

 

 

 

 

Vendor-Unique Format. This format is valid only for the READ

 

 

 

110b

DEFECT DATA commands. The data 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.

Table 5-142shows the Block Format returned when the Defect List Format is 000b.
