What is a Hard Disk?

A Hard Disk is the place where all the personal files, folders and operating system files are stored in; it consists of several physical cylinders (called Platters) with heads pointing on them (as shown in the picture below), the cylinders spins and the hears moving over them to perform the read/write operations, it’s life time around 3-4 years.

Note: The heads are not touching the surface of the cylinders hence there is a very small distance between the heads tips and the cylinders surfaces which called floating height or flying height of around micro millimeters and all those physical pieces are located inside a very clean environmental box.


How to take care of my Hard Disks to extend their life time?

  1. The more time of usage the less life time, so in case if you don’t use the computer for a long time don’t leave it on but instead shut it down.
  2. (In case you have a PC) Don’t turn off the power from the main socket or take the main power cable out from the computer box (in case of a computer hang), instead keep on pressing the main power button (in front of the computer case) for 5 seconds then the computer will shut down automatically and safely.
  3. Prevent vibration and always handle your PC case or Laptop so smoothly.
  4. Don’t perform normal format but instead use the fast format always.
  5. Be sure to connect the power cable to a wall face plate socket that has a grounding connection port.
