*1 If the command is terminated due to an error, the remaining number of
sectors of which data was not transferred is set in this register.
(8) 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.
