TB: A Transfer Block bit of 1 indicates that a data block not recovered in a READ
operation within the recovery limits specified shall be transferred to the Initiator. A TB
bit of 0 indicates that the failing data block shall not be transferred to the Initiator.
The default value on power-up / reset condition is zero. This value is changeable by
the Host.
EER: An Enable Error Recovery bit of 1 instructs the drive to apply ECC before
attempting read retries. A 0 instructs the drive to exhaust the read retry count first
then apply ECC. The power-up default is 1 and may not be changed by the Host.
PER: A Post Error Reporting bit of 1 instructs the drive to report Check Condition
status on a recovered error. A 0 instructs the drive not to report Check Condition
status on a recovered error. The power-up default is 0. The value may be changed,
but the drive always operates as though the value is 0.
DTE: The Disable Transfer on Error bit is valid only if PER is set to 1. A 1 instructs
the drive not to transfer recovered data. A 0 instructs the drive to transfer recovered
data. The power-up default is 0. The value may be changed, but the drive always
operates as though the value is 0.
DCR: The Disable Correction bit is valid only if EER is 0. A 1 instructs the drive not to
apply ECC on a block in error; the drive will do a retry instead. A 0 instructs the drive
to apply ECC on a block in error. The power-up default is 0. The value may be
changed, but the drive always operates as though the value is 0.
Read Retry Count: Specifies the number of times that the target should attempt its
read recovery algorithm. The Read Retry Count depends upon the format being
written. Its value is not changeable by the Host.
Write Retry Count: This count is ignored and is not used by the drive.
