What difference does it make

Whenever I ask this question,on most any sight, I get a blank. One last try before I jettison another Microsoft influenced sight. Does System Restore do anything for non system root drives. I know it says it is monitoring to the tune of 12% of your drive but does that mean anything concrete? This is the third time I have asked this here without an answer but that's still better then the 5 times I have asked Microsoft. I am thinking that disabling restore in drives other then C: (system root) is the way to go since Microsoft nor it's acolyte sites never even address the question.
PS Three, now four times you have deleted my post for no sub category which I clearly had. Not only can't you answer questions but you get around that with deletions unless it's a bug which speaks volumes about you. I pretty much hate your ad driven, non responsive site.It's back to Black Viper,Shell City and Rotation for me. You sir offer little value and your site is just difficult to navigate with mistake or a bug causing deletion. It's obvious you don't care but I started this so that's my honest opinion.
No need to answer the original question since I can't trust someone who can't run their own bug free web site. Good bye and Good luck

HUH?! Was there a question be asked or not?

I tend to turn mine off as well. It did save me in one instance but I rebuild my PCs so often that it really doesn't matter whether it is on or off anyway. Most people have so much hard drive space available now that the space it takes is minimal. If anything, lower the amount of space it can use.
