I bought a Sony Vaio SZ laptop a couple of weeks back and had a problem with the hard drive making a strange clunking noise when idling. Sometimes it's just occasional, but sometimes it happens every few seconds. Sony replaced the laptop (there were also some other problems), but I've just received the new one, and it's doing the same.
The noise sounds almost exactly like this:
From reading around on a few forums, I'm pretty sure that the noise is coming from the hard drive heads parking. Seems to be something to do with the agressive power management, but I've tried tweaking my settings and it doesn't make any difference.
There's some software called hdapm which sometimes fixes the problem on macs, but I haven't found anything similar for Windows.
I guess I need some way of stopping the heads from parking, or stopping the hard drive from being accessed so frequently when idling.
Can you help?
