3.66 WRITE AND VERIFY (16) command
The WRITE AND VERIFY (16) command (see table 223) requests that the device server transfer the specified logical block(s) from
the data-out buffer, write them to the medium, and then verify that they are correctly written. Each logical block includes user
data and may include protection information, based on the WRPROTECT field and the medium format. The logical blocks are
only transferred once from the data-out buffer to the device server.
See the WRITE AND VERIFY (10) command (see 3.64) for the definitions of the fields in this command.
