    The last couple of days my pc's hard drive has been turning/running without any stop as long as the machine is on. I have not insatlled any new software or hardware in a long time.

    I've run the following scans:
    1) TrendMicro's HouseCall (online) which didn't come up with anything.
    2) SpyBot: nothing
    3) Ewido anti-malware: nothing
    4) Microsoft's malware program: nothing
    5) Microsoft's virus scan (using OneCare Live Beta)
    6) Ad-Aware: found 1 Tracking cookie (a data miner, IECache Entry)
    7) Windows Defender is running all the time
    8) I've deleted all cookies, emptied temp files and IE temp files
    9) I've performed disk clean-up using Windows disk clean
    10) Did disk defrag last Wednesday
    11) Performed Norton on-line virus scan: nothing
    12) Performed Norton on-line security scan: nothing

    Any idea what else I can try?

    I have Windows Desktop Search installed, but even when I stop it from running, my hard disk continues to run so I don't think this is the issue.

    Run it in safemode and see if it keeps running.

    I did reboot to "Safe Mode" and the hard drive continued the same way as in normal mode. It kept turning.

    Then I did the following:

    I went to msconfig ---> Services ---> Checked "Hide All Microsoft Services" ---> The "Disable All". Then I went to "Startup" ---> "Disable All".
    Restarted the computer.
    Hard drive is still turning all the time. CPU usage is 1-3%.

    What's next?

    Do you actually hear it running? It can't be doing much if the cpu usage is so low.

    Boot up in Safe Mode or a Clean boot and see if you can tell what it is doing by using Filemon:


    Does Windows Desktop Search install a service?

    Mine is exactally the same. as soon as my pc goes on and im sitting on desktop with nothing running the hard drive is constantly screeching etc and my sidebar says disk busy - 100% and my cpu is at like 5% usage. this never used to happen.

    I'm a little confused as to just what you mean by the "Hard drive is always running". Are you talking about the led that indicates hard drive activity? Is there an actual audible sound coming from your HDD? You may have some background program doing some housekeeping or any number of innocuous operations

    Under normal use, the drive disks will always be spinning. The only exception would be if you have the power options settings adjusted to turn off the hard disks after some period of time. Also. as metioned earlier, 1% - 3% is not much CPU usage. I'm not sure you have anything to be concerned about.
