A couple of week ago I built my first media PC. One of the main requirements for this computer was that it should be silent
. So far Iâ€™ve been testing different software to get the best media PC functionality and finally ended up using Media Portal with a few plugins and tweaking some Windows settings.
Leaning back on the couch ready to enjoy my new media center I discovered that there is disk access every few seconds even when the system is idling (no media center activity). This is totally unacceptable as disk activity generates both noise and HDD led flash (additionally there should be no reason for the constant disk access).
Time for some diagnostics.
1) Check that the windows indexing function is turned off.
- Yes, it is!
2) Download and install Process Explorer http://www.microsoft.com/technet/sysint ... lorer.mspx
3) Discover which process is the culprit.
- Div. Avast Home Edition services (my antivirus solution)
Assuming that lsass and csrss activity was caused by the antivirus activity I stopped all antivirus processes, set them to manual start and rebooted. Resultâ€¦
â€¦ no antivirus processes causing disk access, but still disk access from lsass.exe and csrss.exe.
After googling a bit I discover this gem.
Basically telling me that Windows optimizes my harddisk whenever the computer is idle.
I download and install Tweak UI, uncheck "Optimize hard disk when idleâ€
