The first generation of computer hard drives was created in 1981. Since that time hard drives have gone through a metamorphosis, becoming much more sophisticated. While the physical size of most disks has remained virtually the same for over 25 years (a diameter of 3 1/2" for desktops and 2 1/2" for laptops), the capacity for data storage has increased dramatically. From a capacity of 2MG to the currently available drives of 500GB, the equivalent of hundreds of pounds of information is now being stuffed into the old 2 pound sack. The early hard drives interfaced with the computer's CPU through internal boards plugged into AGP slots to read and write data (dumb drives). The present generation of drives, referred to as "smart drives," uses sophisticated chips on the logic board to access information, i.e., caching chips, BIOS, and servo recognition, enhancing the speed of the read/write mechanism through the heads. Due to cramming more information into the same physical space desktop and laptop hard drives are now more prone to thermal problems (heat), unrecognized servo, BIOS errors, read/write errors, platter vibration, and chip malfunctions.
