benyben, a cloned drive is simply a hard drive that has been cloned/mirrored from another drive (as its source).  casascius has his mining rig set up, and sells drives that are perfect mirrors of his setup.  So if you got a drive like that from him, it'd be a plug and play type of thing, assuming some hardware matches.

There are quite a few users with impressive rigs on the site.  They would all have tokens of wisdom to smooth any bumps on your mining path.

Check out some of the Youtube videos that casascius recently created.  He goes pretty in-depth into what it would take.  I'm sure he wouldn't even mind telling you the exact hardware he uses (if he hasn't posted on here already).  I believe he also offers a cloned drive that you can purchase which can get you that much further faster.

puddin, is this okay to use on 64-bit systems?  I'm running Windows 7 64-bit, and am unable to view any settings when clicking on the Settings button.
