Correctable Data Read Error
This error is a correctable ECC error when data are being read. Processing methods when this
error is detected differ depending on the values specified in the EER flag and DCR flag in the
MODE SELECT parameters.
If immediate correction of errors is permitted (DCR = 0, EER = 1), the IDD immediately
makes error corrections in the data buffer and sends the corrected data to the INIT. Also, in
the case of Verify processing, at the point when it judges that correction is possible, it regards
verification as being successful and continues processing of subsequent data blocks.
If error correction is permitted but immediate correction is not permitted (DCR = 0, EER = 0),
reading of data as in item (2) is retried up to the number of times specified in the other MODE
SELECT parameters ("Number of Retries during Read" or "Number of Retries during Write").
If error correction is prohibited (DCR = 1, EER = 0), reading of data as in item (2) is retried up
to the number of times specified in "Number of Retries during Read" or "Number of Retries
during Write."
If the error cannot be recovered from even when this retry processing is executed, the IDD
terminates the command that is currently being executed with a CHECK CONDITION status.
The sense key in the sense data at this time is "MEDIUM ERROR [=3]" and the sense code
indicates "Unrecovered read error [=11-00]."

Other Internal IDD Errors
If an irrecoverable error other than those in items (1) ~ (3) above is detected internally in the
IDD, the IDD terminates the command that is currently being executed with a CHECK
CONDITION status. The sense key in the sense data at this time is "HARDWARE ERROR
[=4]."
