I tried that once, and dd bombed saying that the maximum file size of 2GB had been reached. Of course, I was copying to a file first, because I didn't trust writing directly to another partition like that. Does that get around the 2GB limit? Also, doesn't writing the image of a disk on another make the second drive think it's the same size as the first? I've copied manually, an entire Linux filesystem several times as I experimented, and it can be done with a bit of effort. Also, parted runs under Linux and can copy DOS or Windows partitions across from one drive to another and set the size on the new drive correctly.
