Spoon - a suggestion for odd drive behaviors:
The free ImgBurn package ( http://www.imgburn.com/ ) has an option called "Tools/Filter Driver Load Order..." which shows all of the filter drivers on the system. It also has a Copy To Clipboard button which produces output, such as this from my thinkpad showing at seven (by my count) third-party filter drivers:

Might asking users with odd drive behaviors to provide this sometimes be useful?
