  ST3500320NS	BB12
	ST3750330NS	BB12
	ST31000340NS	BB12
	This code addresses a rare potential for data corruption.
     	When a write is issued while the drive write cache is
     	enabled and a read-verify is performed immediately afterwards,
     	undetected data corruption can occur. For this issue to occur, the
     	drive write cache must be enabled.

  	Fixes a potential data loss situatiom.
    	After a power cycle, the drive is no longer available
     	and becomes unresponsive. Data may become inaccessible due to the
     	drive not responding.
