SCSI Description
Maxtor Atlas 10K III 5-121
Table 5-154 REASSIGN BLOCKS Defect Descriptor-Data Format
The drive returns a CHECK CONDITION status if it cannot complete the
command. If this happens because the drive ran out of spare sectors, the drive sets the
sense key to MEDIUM ERROR and the additional sense code to NO DEFECT
SPARE LOCATION AVAILABLE. The sense key and additional sense key are set
appropriately for any other cause. The Logical Block Address of the first defect
descriptor not reassigned is returned in the command-specific information field of the
sense data. If all defects were reassigned, but some other error occurred, then
FFFFFFFFh is posted in the command-specific field.
