Vibrations, Mortal Enemies of HDDs

Less dramatic but likewise common is the drumming on a somewhat fragile desk or bouncing of objects like bouncing balls of computer cases or simply hitting the case with the vacuum cleaner. This kind of scenario can cause vibrations that are the worst possible scenario for any HDD. If a drive can sustain a shock of 30-50G, the tolerance towards vibrations is usually only 1% of the shock tolerance. Typical values are in the order of 0.5-0.7G. It is happening every day. Transporting systems back and forth to LAN parties falls into the same category, in cases like that I always remove the HDD and transport it separately.

Informative and interesting. One thing I have always wanted to find out and settle. Hope that you can help me.

Referring to the above vibration, my Dell desktop is sitting on the table together with the 2 side speakers and a subwoofer (part of the Dell package) and also 2 WD NAS HDD.

I do turn up the speakers volume (subwoofer as well) when the music is nice. Will that resulting vibration cause any problem to the PC and NAS HDD? Or too small to be of concern?

Thanks.

Just a small vibration won't do issue to HDD i guess...

Unless your woofer sound so loud that your PC started to bounce 

Hope not. Can feel slight vibration on the table with the sub woofer on. Thing is, how much vibration is OK. Hard to tell.

Thanks alot for this tips

The one thing no one mentions on how to kill a hard drive, the sure way. Just connect the wrong voltage and it'd die straight away, for WD drives they are very very sensitive to voltage and they die from a surge versus other drive brands.

anybody hav any solution for repairing hdd??

haha
