What an excellent idea. I think I can do that, I just need to work out the mechanics of cloning (Acronis? Linux? Ghost? ??) and I can clone to one of my old 300GB drives using my external SATA dock.

300GB... hmm, I could partition it into three 100GB partitions, and alternate A-B-C clones and have the ability to return to a previous configuration.
