Hard Disk Crash - What, Why, How


What


The hard disk crash is a terrible event in which your hard disk is, to put it bluntly, rendered useless. In fact for most people, their computer is now a useless space consuming white elephant once the hard disk is dead.


In a hard disk crash, the hard disk itself has suffered physical damage, owning to mechanical failings in the hard disk itself. The failing causes the read write head (read about hard disk parts here) to crash onto the platters (which is where the data is stored), thereby physically scraping away at your precious data. In worse cases, data is ground to dust. Literally.


In this generation of cable television and Ipods, the computer isn’t the only device which suffers from the hard disk crash epidemic. Here are (some) devices and peripherals which depend on hard disks.


  • Mp3 players
  • Hdd recorders (for cable, television)
  • Game consoles
  • Video cameras

You can see how a hard disk crash can affect your daily life, let alone your work or business.



Why


  • The hard disk crashes due to mechanical failures. The catalyst for the failure however, is varied.
  • Dust introduced, which affects the airpocket holding the read/write head above the platters.
  • Physical shocks during operation (laptop/notebook users, take note)
  • Physical shocks during inactivity
  • Wear and tear
  • Power Surge

During normal operation, the read/write head floats above the platters on a very thin layer of air. Any interruptions can cause this layer of air to disappear/dissipate, albeit temporarily. If there is no air to support the floating read/write head, what is holding it up?


Nothing. Which causes the read/write head to drop/crash/bump onto the platters.



How


Not how hard disk crash (clue: read the previous paragraphs), but how does one get back on his/her feet after a hard disk crash.


First – get a new hard disk. You need it.


Second – consider the data; is it valuable? Do you need it urgently? How important is it?


Third – go for data recovery service if need be. Sure, it is expensive. But so is losing the database of customers information


Fourth – LEARN. Backup. Save often. Get a power surge protector. There are many things that you can do to prevent or help yourself during hard disk crash.
