Parameter Data Format
c. TB (transfer block)
"1": Data blocks which contain errors that are impossible to correct are
transferred to the INIT during a read operation.
"0": Data blocks which contain errors that are impossible to correct are not
transferred to the INIT during a read operation.
d. RC (read continuous)
This bit specifies continuous transfer of all the data requested by a command
unaccompanied by a delay for executing error recovery processing.
The HDD disregards the specification in this bit and operates according to the
default value (=0).
e. EER (enable early recovery)
"1": When a correctable data check has been detected, data correction
according to the ECC is applied immediately without executing retry
(rereading) up to the number of times specified in the "Number of retries
during READ" parameter.
"0": When a correctable data check has been detected, retry (rereading) is
executed up to the number of times specified in the "Number of retries
during READ" parameter, then data correction according to the ECC is
applied if possible.
The HDD disregards this bit and operates according to the default value (=1).
f. PER (post error)
"1": When several errors (errors related to the disk drive), which were
recovered from normally through the HDD's error recovery processing,
have been detected, a CHECK CONDITION status is reported when
execution of that command is completed. In the sense data generated at
this time, the sense key indicates "RECOVERED ERROR [=1]" and the
content of the final error to be corrected successfully is reported.
"0": Even when several errors (errors related to the disk drive), which were
recovered from normally through the HDD's error recovery processing,
have been detected, that command is completed with a GOOD status and
the contents of the recovered errors are not reported.
g. DTE (disable transfer on error)
"1": Even when several errors on the disk drive, which were recovered from
normally through the HDD's error recovery processing, have been
detected, execution of that command terminates at that point.
"0": When several errors on the disk drive, which were recovered from
normally through the HDD's error recovery processing, have been
detected, execution of that command is continued.
The HDD disregards this bit and operates according to the default value (=0).
