What are the main causes of harddisk failure?

Question

If posible there solution.

Answer 1

Usuaully old age, or incorrect shutdown procedures.

Cure : Depends "how" they fail.

If it developes bad soctors, copy off all data you can, and try a low level format, but bad sectors often return and breed, so new HDD is better option

Mechanical failure / circuit board failure, new HDD and put old in a USB caddy to try to recover what data you can

Rule 1 on computing, HAVE a working BACKUP

Answer 2

good question,

As with any hardware, there is always an element of risk. Usually, if a component is good for the first 3 days, it will be good for a while.

I feel that overheating is a bad problem. If your HDs are too close in the case, this will lead to quicker failure. However, most ATX cases provide a spot to put fans close to your HDs, so adding extras is a good idea.

Another possibility is overuse. Sadly, BT causes a lot of use, because files are constantly being written/overwritten/deleted. This is never a good thing, kinda like a car engine: no matter the quality, millions of km will wear it out.

Lastly, moving your computer around whilst your computer is on can cause the parts to warp. Makes sense, there is no shock absorbers.

Solution: lots of computer fans, low movement, cool dry room, and you should be good to go

Answer 3

smoking the residue is corrosive to the sealants used to close the hdd also impacts magnetic fields and water lol as far as fixing it i have seen it done some times replacing the ide circuit board will repair a malfunctioning hdd but if it is the disk itself it is a paperweight unless you are the doj, doe, nsa, cia or fbi the price of recovering a bad hdd is extremely high

Answer 4

Bad tracks, it happens when you UN plug the computer or shutting the computer off while it is working without exiting the computer the proper way.
