Fibre Channel Interface Manual, Rev. D 167
A value for Defect Bytes from Index of FFFFFFFFh (i.e., reassign the entire track) is illegal for the disc drive.
Information in this table is repeated for each defect.
For defects to be specified in the Physical Sector format, the Defect List format field (Byte 1, bits 2, 1, 0) must
be 101 (binary). See Tables 96 and 97.
Each defect descriptor for the Physical Sector format specifies a sector size defect location comprised of the
cylinder number of the defect, the head number of the defect and the defect sector number.
The defect descriptors are in ascending order. The drive may return Check Condition if the defect descriptors
are not in ascending order. For determining ascending order, the Cylinder Number of the defect is considered
the most significant part of the address and the Defect Sector Number is considered the least significant part of
the address.
A value for Defect Sector Number of FFFFFFFFh (i.e., reassign the entire track) is illegal for the disc drive.
