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.

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 HDD 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.

If a value specifying a length (other than zero) that does not match the data format on the disk media is specified in the "Transfer byte length" field in the CDB, that command is terminated with a CHECK CONDITION status without data being transferred to the INIT. The sense data at this time indicate the following contents and the INIT can determine the correct "Transfer byte length" from their contents.
