<b>BRUNCH</b>
	<b># DRIVE OPERATIONS</b>
	
	<b>DANGER</b>
		MULTIPLE SCAN FAILURES, USAGE NOT RECOMMENDED.
	
	<b>CAUTION</b>
		<b>THIS MODULE IS USED FOR ERASING PERSISTANT STORAGE DEVICES LIKE:</b>
		<b>SOLID STATE DRIVES, HARD DRIVES, SD CARDS, MICRO SD CARDS, FLASH DRIVES</b>
	
	
	<b>FUNCTIONS</b>
		THESE NEED ACCESS TO BLOCK SPECIAL FILE PATH WHERE DRIVE IS ATTACHED.
			EXAMPLE: /dev/sd----
		
		CONCEPTS:
			MEAL:  THIS IS THE ENTIRE SPAN OF INDEXES TO BE READ
			PLATE: THIS IS THE ONE SPAN OF INDEXES WITHIN THE MEAL
			
		"DRIVE INFORMATION" SECTION BELOW HAS INFO PERTAINING TO FINDING
		THE BYTES COUNT OF A DRIVE.
