Value Description
10h
If data transfer can be maintained, the maximum error recovery procedures available
are used. (RC=1) If an error occurs which is uncorrectable with the error correction
codes (ECC) on the media, or is uncorrectable in time to maintain data transfer, the
data transfer is not terminated. However, when the data transfer has completed Check
Condition status is reported. The sense key is set to Medium Error. the information
bytes give the address of the block where the first unrecovered error was detected.
Recovered errors are not reported.
11h
If data transfer can be maintained, retries of the read operation and CIRC are used
(layered error correction is not used). (RC=1) Only CIRC unrecovered data errors are
reported. If a CIRC unrecovered data error occurs, data transfer is not terminated.
However, when the data transfer has completed Check Condition status is reported.
The sense key is set to Medium Error. The information bytes give the address of the
block where the first unrecovered error was detected. Recovered errors are not
reported.
14h
If data transfer can be maintained, the maximum error recovery procedures available
are used. (RC = 1.) Recovered data errors are reported. If a recovered data error
occurs, data transfer is not terminated. However, when the data transfer has
completed Check Condition status is reported. The sense key is set to Recovered
Error. The information bytes give the address of the block where a recovered data
error was detected. If an data error occurs which is uncorrectable with the ECC
information available on the media, or is uncorrectable in time to maintain data
transfer, the data transfer is not terminated. However, when the data transfer has
completed Check Condition status is reported. The sense key is set to Medium Error.
The information bytes give the address of the block where the first uncorrectable
error was detected. Reporting unrecovered errors takes precedence over reporting
recovered errors.
15h
If data transfer can be maintained, retries of the read operation and CIRC are used
(layered error corrections not used). (RC = 1.) Recovered data errors are reported. If
a recovered data error occurs, data transfer is not terminated. However, when the data
transfer has completed Check Condition status is reported. The sense key is set to
Recovered Error. The information bytes give the address of the block where a CIRC
recovered data error was detected. If an unrecovered data error occurs, data transfer is
not terminated. However, when the data transfer has completed Check Condition
status is reported. The sense key is set to Medium Error. The information bytes give
the address of the block where the first unrecovered error was detected. Reporting
unrecovered errors takes precedence over reporting recovered errors.
20h
The maximum error recovery procedures available are used. If an error occurs which
is uncorrectable with the error correction codes (ECC) on the media, data transfer is
terminated with Check Condition status. The lock with the error is transferred. The
sense key is set to Medium Error. The information bytes give the address of the block
where the unrecovered error was detected. Recovered errors are not reported.
