Figure 102. Format of REASSIGN BLOCKS data
Note: If the file finds a defective block by verifying ECC before it finds a spare, the file will not start the
REASSIGN BLOCKS process, but will return CHECK CONDITION status with sense key set to
M E D I U M E R R O R .
Defect List Length must be 4,8,12 or 16. Otherwise, the drive returns Check Condition with Sense key
= Illegal request.
Defective Logical Block Address is 4 bytes in length. The initiator can specify from 1 to 4 Defective
Logical Block Address according to the Defect List Length from 4 to 16, respectively. Defective Logical
Block Addresses must be ordered in ascending order, or the drive returns Check Condition.
