What you are seeing is a cosmetic error, nothing more, and a result of
having more than 32GB of free space on the drive in questions. For more
details see cosmetic error (See MS KB272620 - "Negative Hard Disk Free
Size Reported on Virtual Memory Tab in System Properties"
(http://support.microsoft.com?kbid=272620) where you will find it states
"You can ignore the incorrectly listed free space because Windows
internally interprets the numbers correctly as large positive numbers.").
