When this bit is "1", it indicated that the IDD shall access the media in performing the command prior to returning GOOD status. WRITE commands shall not return GOOD status until the logical blocks have actually been written on the media (i.e., the data is not write cached).

This command transfers the number of blocks of data specified in the "Transfer block count" field from the INIT and writes them in continuous logical data blocks with the logical data block on the disk media specified in the "Logical block address" field in the CDB as the top, then reads those data and performs a Verify check.

The functions of this command related to write operations are the same as those of the WRITE EXTENDED command (Section 3.2.4), with the exception that the write cache function cannot be applied. When zero is specified in the "Transfer block count," this command is terminated normally without performing seek or pre-fetch.

The specification in bit 4 of CDB byte 1 is disabled in the IDD and the specified value is disregarded.

The Verify check executed by this command is the ECC (data portion) normalcy check only. error recovery processing when the verify check is executed is according tot he mode specified by the MODE SELECT parameters (Verify error recovery parameter). For example, if data correction processing is not prohibited, even if a correctable data check is detected during the verify check, it is regarded as if the verify check succeeded.
