Why Do Hard Drives Fail?
It is very easy to forget how long we can all spend working on an important university or business document or PowerPoint presentation, if you were to add it all up it could amount to days and on occasions weeks but what do you do when you suddenly find the file has simply vanished from your computer.
You check your deleted files with no luck and do a full search on your computer but the file or folder has simply vanished. In all probability the file is still on your hard disk but for some reason cannot be found which may be the first signs of a degraded drive.
It would be nice to think that your hard drive will remain reliable for ever until the day you renew your computer but like most things mechanical drive failures do occur it would seem far more often than you would expect especially given the manufacturers mean time between failure specifications that come with a new hard drive or can be found on the manufacturers website.
But oh if life was so simple!
A question often asked is how long should a hard drive be expected to last before requiring replacement?
This is a very difficult question to answer and also opens up a whole host of other factors that need to be taken into consideration as well.
The first major aspect is of course the use that a computer is put through during its lifespan. Many home users only use their Pc very occasionally and store relatively small numbers of files or photos. In this scenario it would be nice to expect a drive to last over 5 years (don't assume this though).
Pretty much the same could be said for a mid usage machine as well for example a pc used for office work or accounts perhaps. So you may never experience drive degradation or drive failure.
But if your system is used for extreme gaming, computer aided design, Digital content creation or virtual prototyping then the hard disk will be working massively harder than in the previous two scenario's so it would only be expected that true life expectancy would be a lot shorter.
High end computer users using high end applications will often have a much shorter expected life of their system, and desktop refresh tends to be around 3 years or so to avoid disk failure and to keep them at the cutting edge of computing productivity which is important for a business.
If a hard working drive's life were to be extended then it would be reasonable to see an increasing ramp up in disk failures over time or drive degradation.
During challenging economic times, business computer refresh programs are often put of to protect working capital which on the face of it can be seen as a sound business decision but there can be a large bite to this policy if an essential drive or server fails with a resultant loss of business critical data.
Computer support and repair companies advising businesses that are intending to stretch there refresh policies would be advised to ensure they have adequate desktop or online data backup protocols in place to be on the safe side.
Other factors affecting hard disk lifespan are the environment the computer is running in and basic system maintenance for example a poorly maintained Pc can become literally clogged with dust and get very hot. Heat is a major factor of drive failure as is hard disk fragmentation, so proper system maintenance is conducive to reliable disk performance.
Your lost file should be easily recoverable but you do need to bear in mind that any further information written to your hard drive can over write the file you are trying to save. This often happens with data recovery software so if diy recovery is your choice be warned.
Your local data recovery provider will be able to help with all your hard drive recovery and file recovery
needs and will do there utmost to ensure the original data integrity is maintained.
