SubjectRe: [LINUX-KERNEL] HDD Noise stopped with cat /dev/zero
Dunno - but I have an old machine where I can here noises from the ancient hard
drive (we are talking 8 year old 40Mb MFM here) when network traffic is going
through the machine - go figure. (And no, it isn't the drive doing things -
the disk select light (remember those?) isn't even on). If I have the sound
card plugged in I get to listen to the traffic quite loudly too :-(

I've also had at least two machines which made strange noises when the case was
open and in quiet surroundings with no sound card or anything - again network
traffic was triggering the noises, though I have no idea why I could hear it.
I can remember one particularly strange incident where I could here noises
when I was running a CPU intensive job (raytracing) as opposed to the machine
being idle. I can only guess I am hearing subharmonics of the bus traffic but
I find that hard to believe.

Just one of those things I guess.
