I use this at work and its great. One of my jobs is a breakfix technician and I have 2 notebook hard drives in external bays that I have loaded down with various programs and tools using pstart as an autorun menu on it. The boss also has one. I put updated tools and new tools on the server and we use the synctoy to up date our drives super easily. We use the echo method, since we only do updates on the server, never the drive. Works like a champ.
