|I have my primary hard drive partitioned into two, one for OS and programs, and one for files. Then I took the harddrive from my old computer, installed it internal, copied over my files, formatted it clean and I use it as a back up destination for all personal files (system and programs I can reinstall).|

You have to be a little bit crazy to keep you from going insane.
If all else fails, read instructions.
