Table 1.6 Reset processing during write
Type of command Halting process of 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 TASK SET 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 (Specifying parameter save)
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.
