I've used the WD edition of Acronis to clone HD to HD and it worked well.
I've been told that there is a forum on the Acronis website, you might check there.
I've also been told that cloning a Win7 install is more difficult because of the additional system recovery partition, etc. I tried a clone using Norton Ghost and had to do some research on the Norton forum to figure it out. You might have to do the same on the Acronis forum.
