Should I be worried?

[Mzmkont]

Hello everybody,
I don't know if that's a problem or not, but while I was surfing the web I heard a sound. It was like ''chhh chh'' but it wasn't loud if I wanted to hear it i would need to put my ear next to my laptop keyboard to hear that sound. This sound i think is from the hard disk and sometimes there is that sound and sometimes not.

So is it normal or is it something with my hard disk?
750GB 7500RPM

Thank you guys.

Probably just normal noise from the hard drive. They are usually spun down sooner on laptops to conserve power. It may also be the cooling for the CPU you heard which can ramp up and down and is sometimes imperceptible outside of a very quiet environment.

What BigPinkDragon286 said, it's probably nothing.

It's never a bad idea to back up your important data though.

 

[Mzmkont]

Yeah, it's 100% my hard drive. Okay, thanks guys.

Yeah you should be worried, It might blow up

 

[Mzmkont]

Yeah, but it's not hot and as I said it makes a low noise and that's it.

 

[Willdobbo]

You never know man, You never know

 

[Mzmkont]

Yeah, but your hard can blow up too. I think that's normal that electronics sometimes go... you know. So yeah.

All hard drives make noise, they are mechanical, and if you listen to enough of them, you'll get to know the particular range of harmonics to expect from your particular make and model. Not exactly the best analogy, but just as different makes and models of cars produce particular sounds when running, so do hard disks. This is not a proper indication of impending failure. If you are familiar with the noise, and you notice over time that it changes (not to be confused with your perception of it changing,) it could indicate something. Sometimes failure noises produced by a hard drive are not caused by the drive itself, but by faulty power or a bad DATA connection being supplied to the drive. If you're concerned, investigate further.

Also, a cheap, reliable backup is a matching pair of USB thumb sticks. Make the same backup on each, then if one fails, or you screw something up yourself, the statistical chances against them both failing are in your favor. Keep one in a fire proof box with the rest of your valuable documents, or in a safety deposit box if you're really paranoid.
