Fatal hardware errors

(1) Self-diagnostic errors
If a hardware fatal error is detected during the initial self-diagnosis, in off-line self diagnosis or in on-line
self-diagnosis (SEND DIAGNOSTIC command), rotation of the spindle motor will be halted.
When in this state, the IDD reports the CHECK CONDITION status for all input/output operation
requests except the REQUEST SENSE command.
HARDWARE ERROR [=4] / Diagnostic failure on component "nn" [=40-nn]. It is necessary for the
INIT either to generate a RESET condition or send a TARGET RESET message and attempt to recover
from the error state. For recommended procedures for error recovery methods, see the explanation in
Section 5.2 "INIT's Error Recovery Methods (Recommended)." Furthermore, see Section 6.1.1 "Self-
diagnostic Function" in "Product Manual."
(2) Unrecoverable hardware errors
Limited to cases in which a fatal hardware error occurs during execution of a command, and termination
processing such as a CHECK CONDITION status report cannot be executed, the IDD may halt rotation
of the spindle motor.

Table 1.6 Reset processing during write
Halting process of command execution
Data blocks which are currently being written are
processed normally, including the ECC portion, and
execution of the command is terminated at the point when
that processing is completed. Not all the data transferred
from the INIT to the IDD will necessarily be written to the
disk media.
At the point when processing of the data block that is
currently being written (initialized) is completed,
execution of the command is halted. Since the formatting
results cannot be guaranteed for the entire disk surface, it
is necessary for the INIT to reissue the command.
At the point when processing of alternate blocks which are
currently being assigned is completed, execution of the
command is halted. Not all the alternate blocks specified
for reassignment processing by the INIT will necessarily
have been processed.
If a parameter save operation has already started, that
command is executed until it is completed. However,
since the INIT cannot judge whether the parameters have
been saved or not, it is necessary for the INIT to confirm
the status by the MODE SENSE command or the LOG
SENSE command, or reissue the command.
Not all the data which is the write object will necessarily
be written to the disk media.
