Re: [Help] Clicking sound...Possibly from Hard Drive?
said by koitsu:If you have not tried it you should not call it silly.
The described "screwdriver trick" is generally silly (FYI, all this does is turn the screwdriver into an amplifier). "One drive sounding louder than the other" is not going to indicate anything anomalous; for example drives with 3 platters are going to sound louder than those with 2. So this is silly/nonsense.
You take a long Screw driver and you place the tip touching the drive (usually on the side) and put the other end to your ear.
You can hear every noise that the device makes. All things make common noises and if you have a drive make a funny noise you can tell. You will definitely hear a clicking drive and be able to tell which one of the six it is.
That is what he asked to do, how to tell which drive is clicking.
If you have a drive that has a bad bearing you will definitely hear it using the screw driver and can tell which drive it is.
This is like a doctor putting a stethoscope to your chest.

I understand what it does -- like I said, it acts as an amplifier. But like I described, it's silly because 1. you need a frame of reference for it to be useful (meaning you need to know what the drive sounds like "normally"), and 2. every drive sounds different due to platter (thus actuator arm) count and underlying drive mechanics (ex. spindle motor brand) as well as underlying features (ex. NCQ in use or not).
Furthermore, again like I said, the OP can hear the clicking without the use of a screwdriver-as-an-amplifier. It happens occasionally, which means what, he's going to sit with his ear against a screwdriver all day when trying to use the PC? Come on. The noise that is most commonly heard from that distance, which is occasional as well, is the sound of the actuator arm hitting the plastic or metal stop inside of the drive (either inward or outward). This is described in the "click of death" video above (though I want to make clear, the "click of death" is not necessarily applicable here -- I'm just using the term loosely).
If the drive had a bad bearing, he would be hearing this noise constantly, not occasionally/intermittently.
All he has to do is take each disk out of the case/chassis (which he'd have to do anyway to apply a screwdriver tip to the metal casing of the drive!), and eventually he'll figure out which one is causing the noise. Troubleshooting 101 without making things overly complicated.
Let's also not forget that there's no actual hard evidence at this point that a hard disk is the cause of the noise (could be any number of the things I listed off in my last paragraph).
