1 RECOVERED
ERROR
1) Indicates that the command which was executed last was terminated
normally with a recovery operation by the IDD. If multiple errors
which were successfully recovered from during processing of a
single command occurred, the last error to have occurred is
reported.
2) Rounding processing of the MODE SELECT parameter was
performed.
2 NOT READY The disk drive is not in a state where it can be accessed.
3MEDIUM
ERROR
An irrecoverable error was detected due to a defect in the disk media or
an error in the recorded data.
4 HARDWARE
ERROR
The IDD detected an error in the hardware for which recovery processing is
impossible during command execution or self-diagnosis.
5 ILLEGAL
REQUEST
An illegal value was detected in the parameter transferred in the CDB or
the specification in the command. Also, an error in the LUN
specification. If the IDD detects an illegal parameter in the CDB, it
terminates the command without changing the contents of the disk
media. If an illegal parameter is detected in the parameters transferred
from the INIT in the DATA OUT phase, the contents of the disk media
may be changed by that command.
6 UNIT
ATTENTION
A UNIT ATTENTION condition occurred. (See Section 1.5 concerning
details of the UNIT ATTENTION condition.)
