5.3 Host Commands
(4) WRITE VERIFY (X’3C’)
This command operates similarly to the WRITE SECTOR(S) command except
that the device verifies each sector immediately after being written. The verify
operation is a read and check for data errors without data transfer. Any error that
is detected during the verify operation is posted.
After all sectors are verified, the last interruption (INTRQ for command
termination) is generated.
