The WRITE AND VERIFY command writes the number of consecutive data blocks
from the host computer specified in the Transfer Length field to the medium starting
at the block address specified in the Logical Block Address field, after then verify
that the data is correctly written.
The DPO (Disable Page Out) bit is used to determine the priority of the logical block
data read by this command in the cache.
But in this controller, the priority of the retained data is controlled by the value of the
Retention Priority field in the mode page 8 (Caching Parameters; refer to Table 5.36)
or the algorithm implementing the cache replacement strategy irrespective of DPO
bit.
When the BytChk (Byte Check) bit is set to 0, the controller verifies the written data
in the medium using ECC. When the BytChk bit is set to 1, the controller performs
byte-by-byte compare check between the written data in the medium and the
transferred data from the host computer.
