I have an older computer with a 40gb 5400rpm hard drive. I bought a new 200gb 7200rpm hard drive. I want to put the new 200gb hard drive in the old computer as a slave so I can copy all the contents from the old hard drive to the new one. I would like to be able to do OS and all, since i don't have an OS disc for it any more to format with. What is the best way to have ALL the data copied over, OS, all programs, drivers, ect...I wouldn't think it would be an issue since it's going back in the same old machine. Once it's copied over I plan on setting the new 200gb as the master and taking the 40gb out. Please help me out.
