re: Windows Defender

No problem. Consider also that you may be totally fine, just because Windows Defender normally doesn't do this doesn't mean you're screwed. It just looks odd.

That said, I do highly recommend to everyone that you try a disaster recovery dry run before you have to do it for real. It is immensely worth the time and money. All it takes is one blank hard drive (they're dirt cheap) and a weekend of violent cursing when you realize you are fricked despite having a "backup", but it's much better to learn how to do it correctly when it's just for practice.

What I do is just unplug my main drive and pretend it is completely unavailable. It generally takes me slightly over an hour to completely recover, and usually I never plug in the original drive and just carry on with the new one. Once you work through the first 2-3 times you'll work out the kinks and then you won't ever have to worry about this.
