A co-worker recently brought this article to my attention. It’s a little-known trick to use the RoboCopy utility included on the Windows Vista installation media to perform a complete disk-to-disk copy between 2 hard disks – no need for Partition Magic or any other 3rd-party tool. Comes in really handy if you want to upgrade to a bigger hard disk without performing a “nuke & pave” reinstall of the OS.
