I have used SyncToy (no longer available) and FreeFileSync to mirror drives. I thought I had good success. Then I did some manual checking and found they didn't always get it right. Now I use RoboCopy and it seems to always get it right. It comes free with Windows. It isn't user friendly. Once I figured out the correct syntax for what I wanted to do I kept the command in Notepad, then copy and paste to RoboCopy. The results are very quick.
