I have a question about duplicating a hard drive. Is there any cheap way of simply cloning a hard drive for purposes of testing and possible backup? I don't understand why a simple file copy won't cut it for a hard drive that contains an operating system, but I would think that there are simple and cheap software solutions that would let you actually do a true hard drive copy (boot files, boot tables, and all). Thanks for any advice.
To clarify, I would be taking my "C:\" drive out of my windows server (for example) and would want to clone that drive so I could put it in a spare machine and do testing on it without disturbing the "live" server (other than disturbing it initially when I remove it from the server and connect it externally to some host machine or device for cloning).
