How to setup automatic sync with Seagates FreeAgent Go

Coming from XP to Vista is not as difficult as I would expect, though some of the software which I found indispensable in XP is not quite mature enough for a 64-bit version of Vista. One such piece of software is my automatic synchronization of documents to an external harddrive. In XP my FreeAgentGo 160GB external harddrive contained an exact copy of my documents folder - just in case - so big was the surprise when I tried to install the FreeAgent Tool on my 64-bit only to discover that the software wasn't supported on 64-bit OS'es. Having cussed for a while I tried to run the application in Windows 2000 compatability mode, and lo and behold, the installation ran perfectly and post-reboot, the sync is up and running again. Hurrah.
