I'm having the same issue.  My tablet shows 5.92GB total space.  The list of Apps, Pictures, Audio, and Downloads adds up to 2.47GB.  The tablet shows 510MB free.  That's a huge discrepancy.  And I'm sorry, but doing a factory reset is not the answer.  This is obviously happening more often than a freak occurrence and what's to keep this from happening again?  The talk about botched downloads sounds familiar, so it sounds like that's maybe a cause.  I'll keep looking into that around the net.
				
			 
	 
 
		 don't think it means SQUAT!     My Win 7 computer shows 1GB difference between used space and "total minus free" so I woudn't get obsessed over it.
