Defect Bytes from Index is gotten using the following equation:
Bytes from Index = (Physical Sector Number) * N
Where: N = Bytes per sector

The Defect List Format field specifies the format of the defect list data returned by the Target.
The Defect List Length field specifies the length in bytes of the defect descriptors that follow. The Defect List Length is equal
to eight times the number of defect descriptors.
Normally the Target will set the Defect List Length field to the amount of space needed to contain the entire defect list. How-
ever, the Target is capable of building a defect list with a length such that the entire list cannot be transferred using the maxi-
mum allocation length. If the defect list grows beyond 8191 entries, the defect data cannot be transferred with an allocation
length of 0FFFFh. The Target will transfer a partial defect list and return Check Condition status with the sense key set to
Recovered Error and the additional sense code set to Partial Defect List Transferred. The defect list length will be set to
0FFF8h, indicating the maximum number of defect descriptors that can be transferred. Defects beyond this number cannot be
read by the Initiator.
