A hard drive is where all your data is stored, personal and system data. It is kept even when the PC is powered off unlike RAM. It is one of the most vital parts of your PC. Without it you could not store any files or install any application software let alone run it. Due to the sensative nature of a hard drive it is enclosed in a metal case to prevent damage within your system unit. One single particle of dust can crash the hard drive and cause massive data loss. And force you to replace it and reload all of your data. Also it is recommended that you defragment your hard drive as preventative maintence. Also it is recommended not to move your PC while its running because this can cause your hard drive to crash. In order to explain how I would have to talk about the complete architecture of your drive. Computerguy1984
