Table 4.1 Combinations of error recovery flags (4 of 4)
EER PER DTE DCR Error Recovery Procedure
11101.When a correctable data check is detected, immediately, correction is executed
according to the ECC. For data checks which cannot be corrected, rereading is
tried repeatedly up to the number of times specified in the "Read Retry Count",
"Write Retry Count" or "Verify Retry Count" parameter. However, if a
correctable error is detected during reading, data correction is executed at that
point according to the ECC.
2. When error recovery has succeeded, or even when recovery is impossible,
execution of the command is terminated with a CHECK CONDITION status at
the point when error recovery processing is completed, and the sense data
indicate the data block address where that error occurred.
3. Transfer to the INIT of data in blocks with recovered errors is done, but transfer
to the INIT of data blocks in which the errors were unrecoverable is done in
accordance with the specification in the TB bit (read commands).

(Setting prohibited)
(See *1 at the end of this table.)
*1 If a setting-prohibited combination of error recovery flags is specified, the MODE SELECT or
MODE SELECT EXTENDED command is terminated with a CHECK CONDITION status
(ILLEGAL REQUEST [=5] / Invalid field in parameter list [=26-00]) and all the parameters
specified at that time are disabled.
Remark:
Just as explained for the EER, PER, DTE and DCR bits, the IDD can only make a valid
specification for the PER bit. Therefore, among the error recovery flag combinations listed above,
the only one which can actually operated is (EER, PER, DTE, DCR) = (1, 0, 0, 0) and (1, 1, 0, 0).
