AWRE An Automatic Write Reallocation Enable bit of 1
enables the automatic reallocation of defective sectors
during the write operation of the Write commands
(0AH, 2AH, AAH), Write and Verify commands (2EH,
AEH), and Write Long (3FH, DFH).
For rewritable disks, automatic reallocation of defective
sectors occurs during these additional erase operations:
Erase 2CH and Erase ACH.
AWRE cannot be disabled on Write-Once media.
TB A Transfer Block bit of 1 indicates that a data block that
is not recovered within the recovery limits specified is
transferred to the initiator before CHECK CONDITION
status is returned.
A TB bit of 0 indicates that such a data block is not
transferred to the initiator.
RC A Read Continuous bit of 1 indicates that error
correction codes are not used for data error recovery.
A Read Continuous bit of 0 allows the use of error
correction codes for data error recovery.
