The VERIFY command verifies for the specified number of blocks from the specified logical block address.
Logical Block Address specifies the head logical block address from which verification starts.
Verification Length specifies the number of blocks to be verified and transferred.
When Verification Length is 0, the command verifies no block and ends normally.
The ByteChk bit indicates data compare execution. However, since the ByteChk is not supported, it must be set to 0. If a value 1 is specified, the command ends with Check Condition.
