This command writes the data block data transferred from the INIT, together with the ECC to form
bytes, in the logical data blocks on the disk media specified in the “Logical block address” field in
the CDB. Normally, this command is used for checking the ECC function in combination with the
READ LONG command.
bytes, in the logical data blocks on the disk media specified in the “Logical block address” field in
the CDB. Normally, this command is used for checking the ECC function in combination with the
READ LONG command.
The object of this command’s operation is only 1 data block. Also, the data transferred from the
INIT by this command must have the same order and the same length as the data transferred to the
INIT from the IDD by the READ LONG command.
INIT by this command must have the same order and the same length as the data transferred to the
INIT from the IDD by the READ LONG command.
The “Transfer byte length” field in the CDB indicates the number of bytes of data transferred from
the INIT by this command. When the “Transfer byte length” specification is zero, this command is
terminated normally without performing anything.
