Common Problems Why Hard Disks Crash
There are so many reasons why your hard disk may crashed:
(1) It may be caused by mechanical or physical problem such asthe spindle motor system failure. This failure is usually causedby over-heating. The activity light flashing that you see onyour CPU (central processing unit) indicates that its head movesto different tracks. If this movement fails, it can no longerread or write data. Remember, a hard disk is a hardwarecomponent, not a software. It is a magnetic device use to storedata, it reads and writes data as it spins.
(2) Failure of logical system (the logical partitioned drivesassigned as C, D, E, F, G) may be caused by and not limited tocorrupt system files, corrupt firmware, registry components andvirus infection. Spywares, adwares & all other malicious filesmay also cause your hard disk to crash.
HINTS:
(1) If you see the activity light flashing but the computer doesnot boot, the case may be, your files is still intact on thehard drive but becomes inaccessible -- this may be because oflogical system failure. Try booting through a floppy disk or usethe start-up disk that came with the system.
(2) If you don't see any activity light flashing on the CPU andthat the system can not start up (ofcourse after checking allpower cables are "on") then it is likely of mechanical problem.And notice that if the system BIOS (Basic Input/Output System)can no longer recognize the hard drive, then it is thephysical/mechanical system that failed.
The good news is, usually, in today's
technology on hard disks,if this problem occurs it normally will alarm you and warn youbefore it will totally fails, so you could get that chance toimmediately back up your files. And there are also many datarecovery tools available in the market today. But at times, itis cheaper to replace the hard drive than to fix it(unfortunately).
TIPS & TRICKS TO AVOID THIS DISASTER TO HAPPEN:
1. Keep your hard drive healthy by performing defragmentation atleast once a week (others prefers once every two weeks)
2. Run your anti-virus program everyday! Run spyware/adwareremoval tool at least once every week (there are many availablefree to download). Keep updates with all these tools andprograms too! Turn on your firewall & pop-up blocker, itprotects you from intruders!
3. Remove all unknown emails, clear your bulk and spam emailsimmediately.
4. Delete all internet temporary files (including all offlinefiles)
5. Install all necessary updates on your computer
6. Be very careful in downloading files from different sites(firmware usually fails because of this)
7. The last but not the list - take "backing-up" your hard driveon a removable disk or tape as a serious task for you to do atleast everyday or once a week especially if you are using it forbusiness purposes!
