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 (item 3.2.4), with the exception that the write cache function and
automatic alternate block allocation 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.
