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 IDD 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 IDD's error recovery processing, have been detected, a
CHECK CONDITION status is reported when execution of that command is
completed.
"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 IDD'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 IDD'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 IDD's error recovery processing, have been detected, execution of that command
is continued.
The IDD disregards this bit and operates according to the default value, (=0).
h. DCR (disable correction)
"1" : Even when a correctable data check has been detected, data correction according to
the ECC is prohibited. However, On-the-fly correction processing is not prohibited.
"0" : When a correctable data check has been detected, data correction according to the
ECC is applied.
The IDD disregards this bit and operates according to the default value (=0).
