Value Description
21h
Only retries of the read operation and CIRC are used (layered error correction is not
used). Only CIRC unrecovered data errors are reported. If an CIRC unrecovered data
error occurs data transfer is terminated with Check Condition status. The block 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.
24h
The maximum error recovery procedures available are used. 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 last block where a recovered data error was detected. If a data error occurs which
is uncorrectable with the ECC information available on the media data transfer is
terminated and Check Condition status is reported. The block with the error is
transferred. The sense key is set to Medium Error. The information bytes give the
address of the block where the uncorrectable error was detected.
25h
Only retries of the read operation and CIRC are used (layered error correction is not
used). 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 last block where an CIRC recovered data error was
detected. If an unrecovered data error occurs, data transfer is terminated and Check
Condition status is reported. The block 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.
26h
The maximum error recovery procedures are used. Recovered data errors are
reported. If a recovered data error occurs, data transfer is terminated and Check
Condition status is reported. The block with the recovered error is transferred. The
sense key is set to Recovered Error. The information bytes give the address of the
block where the recovered data error was detected. If a data error occurs which is
uncorrectable with the ECC information on the media, data transfer is terminated
with Check Condition status. The block with the error is transferred. The sense key is
set to Medium Error. The information bytes give the address of the block where the
uncorrectable error was detected.
27h
Only retries of the read operation are used (layer error correction is not used). CIRC
recovered data errors are reported. If a CIRC recovered data error occurs, data
transfer is terminated with Check Condition status. The block with the recovered
error is transferred. The sense key is set to Recovered Error. The information bytes
give the address of the block where the recovered data error was detected. If an CIRC
unrecovered data error occurs, data transfer is terminated with Check Condition
status. The block 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.
