ational status to MAINTENANCE.

Write ID Request message to the CIDRW Controller for Head 1. The
CIDRW Head 1 writes ID, and the CIDRW Controller returns the ID to the host devices.
• Write Data
The host device sends a Write Data Request message to the CIDRW Controller for Head 1 and
DataSeg S02. The CIDRW Head 1 writes the data, and the CIDRW Controller returns the results to the
host device.
