Hard drive reving up periodically..

[Guest]

Whenever I'm on this pc you can hear the hard drive rev up at random times
and I'm not sure if this is normal. I have run adaware se, spybot, yahoo
antispy, avast antivirus and everything is clean. I just want to know if this
action is normal and/or is there a way I can make it stop? This pc is a Sony
Vaio PCV-W30 running Windows XP SP 2. I also have a ton of extra space on
both internal hd's, not sure if that's relevant or not.

I don't know for sure, but, what you may be hearing is your box's cooling
fan revving up, not your HD. Depending on a lot of factors such as a dirty
box interior, programs running in the background, heavy CPU demand, etc.,
this is normal.

What JCA said sounds reasonable, unless you are certain it is, in fact, the
HD. I run my 2005 BMW Mini off my very powerful PC with a remote and at
traffic lights it does rev-up sometimes and the distinctive exhaust sound is
clearly audible to my daughter when she is on the computer at home. Just
kidding.
