How Can I Avoid Hard Drive Failure?
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.
The first thing to do is to do a search of your folders to make sure you have not saved it in the incorrect folder and if this does not fine the elusive file you can also try having a look in the recycle bin to make sure you have not accidently deleted it. If the file can still not be found then this may be indicative that you are suffering from a degraded drive.
Much as we would like to believe a hard drive will not last forever but has a definitive life expectancy which is often referred to as a mean time between failures (MTB). MTB can often be used as a reference to a drive future reliability and calculations would put expected drive failures at less than 0.1 percent.
But oh if life was so simple!
So the big question is when is the best time to renew my hard drive so it does not suffer from any failures?
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 for power users it is an entirely different story. Extreme gamers and users of high end commercial applications will be driving their systems very hard indeed and the amount of data that is shifted into swap files or written back to the disk is huge so its only reasonable to expect disk life to be shorter and the chances of drive failure or disk degradation to be far higher.
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.
Any business should in this day and age have effective online data backup and disaster recovery policies in place especially if postponing a business system upgrade.
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.
Most data recovery experts will be able to restore your deleted or lost files even if your drive has degraded and even if your drive has bad sectors that are unreadable hard drive recovery and data recovery are often very successful.
