User has a 100+ GB drive with only a handful of gigs actually used on it, yet he's getting "The number of Hard Disk Drives in your system has decreased" warnings in Event Viewer.

Google searching isn't revealing much at all, and EventID.net only says that you'll get that error as long as it's configured to warn you at a certain percentage, regardless of HD size. That's great and all, but is there a way to make it stop? He's not even using 5GB on it!
