A hard drive clicking sound can often be heard if your disk is about to fail.
The best thing to do is shut down your computer immediately and call a professional.
I know you may be worried about the cost, but most companies today offer free consultations and evaluations.
A hard drive clicking sound is serious and it is important that you take immediate action and do not cause further damage to your data.
Many people do not even know what to do when this happens and they go about their business.
Your drive may function for awhile but it is much more likely that it will fail and your data will be lost forever.
This is why you have to shut it down and prevent any loose parts from damaging the disk and drive further.
I have been in this spot many times and it can often feel counter-intuitive to shut your computer down because you want to do something about the problem, but trust me on this, you do not want to go in there by yourself and try to fix it.
Many people have lost all of their data and precious memories by doing this when they could have spent a few extra bucks on a professional data recovery service.
Your drive can also make buzzing, whirring and other sounds, which also indicate a problem.
A drive that functions normally should sound normal.
It is never a question of if your hard disk fails but when.
Most people think that their computers will last forever, so they fail to back up their files.
This usually leads to a rude awakening once they experience their first disk failure and lose all their data or possibly have to pay thousands to get their documents and files back because they did not follow the right steps in preventing further damage.
In summary, if you hear a hard drive clicking sound, shut it down immediately and call a professional.
Finding the right professional company is not easy, but do your research and you should be fine.
