One of my hard drive is keep making sudden noise..

Hi everyone,

I'm using 2 hard drives. one is WD 640gb 7200 rpm 3.0gb/s, for the other one all i know is 80gb 5400rpm.. both are sata.

I'm not sure if i have to set any jumper setting.. (i'm sort of noob) but i just plugged in both of them.

In every our or so, I'm hearing noise from one of the hard drive.

Description of that sound: sound like when I turn on/off the computer.

It doesn't make any noise if i unplug one of the hard drive..

Is this normal?

I'll appreciate any input.
Thanks,
Pete

haha no. not the windows startup/updown.
I don't really care about the 80gb but I'm worried that it's my new hdd, 640gb.

I went to WD website and looks like this is the one i have to run: http://support.wdc.com/product/dow [...] =3&lang=en

I filled up 500gb already and I don't have anywhere to back up to.. =::::

have you tried disabling power saving ( the turn off harddrive option specifically) and seeing if the noise stops.

the every hour or so sounds less like a bad drive and more like powersaving doing something goofy.

I had what I though was a drive going bad for the longest time....clicking noises, stuttering, random lockups. I reinstalled everything onto a new drive just to be safe, but left the old drive in as a secondary. It still worked, it just made noise and was flakey acting at times, but I just left it hooked up. Soon after, my PSU died. New quality PSU installed, and guess what, now the drive works perfectly, been runing over 2 months now without a hiccup, and no more noise.

Old PSU -Raidmax Volcano 630 watt. (yeah, I know Raidmax's are junk)
New PSU -BFG 680 watt.
