(19) WRITE LONG (X'32' or X'33')
This command operates similarly to the READ SECTOR(S) command except that the device
writes the data and the ECC bytes transferred from the host system to the disk medium. The device
does not generate ECC bytes by itself. The WRITE LONG command supports only single sector
operation.
This command is operated under the following conditions:
•
The command is issued in a sequence of the READ LONG or WRITE LONG (to the same
address) command issuance. (WRITE LONG command can be continuously issued after the
READ LONG command.)
If above condition is not satisfied, the command operation is not guaranteed.
