Reset Processing During Write
Type of Command
Processing to Halt Command Execution
WRITE
WRITE EXTENDED
WRITE AND VERIFY
SEND DIAGNOSTIC (Write/Read Test)
WRITE LONG
WRITE SAME
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. If the ATN signal is asserted
immediately after data transfer in the Data Out phase (to
the first ACK signal) and the ABORT message is sent,
the data are not written to the disk media.
FORMAT UNIT
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.
REASSIGN BLOCKS
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.
MODE SELECT
MODE SELECT EXTENDED
LOG SENSE (Parameter save
specification)
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.
SYNCHRONIZE CACHE
Data blocks which are currently being written are
processed normally, including the ECC portion and the
command is halted at the point when that processing is
completed. Not all the data which is the write object
will necessarily be written to the disk media.
