The Read-Write Error Recovery page controls the drive’s response to error
conditions that arise during the course of READ (6), READ (10), WRITE (6),
WRITE (10) command processing and during the write portion of WRITE AND
VERIFY command processing. The Read-Write Error Recovery page format and
field descriptions are described in Table 5-64 and Table 5-65 respectively.

PS 1
Parameters Savable. This bit is only used with the MODE SENSE command.
A returned value of 1 indicates that the target is capable of saving the page
in a non-volatile, vendor-specific location. The bit is reserved with the
MODE SELECT command
AWRE 1
Automatic Write Reallocation Enable. When the value is 1, it causes the
drive to automatically reallocate bad sectors encountered during a write op-
eration. If it succeeds in replacing the bad sector, the drive adds the revec-
tored sector’s Logical Block Number to the Grown Defect List. Reallocation
is done only when the drive is able to recover the sector’s data unless the
HrdBBR bit of the Maxtor (Vendor) Special Function Control Page is set.
When AWRE is 0, the drive does not automatically reallocate bad sectors
encountered during a write operation. See also Maxtor-Unique Page 39h.
ARRE 1
Automatic Read Reallocation Enable. When the value is 1, it causes the
drive to automatically reallocate bad sectors encountered during a read op-
eration. If it succeeds in replacing the bad sector, the drive adds the revec-
tored sector’s Logical Block Number to the Grown Defect List. Reallocation
is done only when the drive is able to recover the sector’s data unless the
Reallocate Uncorrected Errors bit of the Maxtor (Vendor) Special Function
Control Page is set.
When ARRE is 0, the drive does not automatically reallocate bad sectors en-
countered during a read operation. See also Maxtor-Unique Page 39h
(RUEE).
TB 0
Transfer Block. When the value is 1, the drive sends best-guess information
to the initiator when it encounters a defective sector whose data cannot be
fully recovered.
When the value is 0, data that cannot be fully recovered is not returned to
the initiator.
