    Suspicious HDD activity.

    Every time my display turns off automatically I can see my HDD light flashing and I can hear it. When display comes active it stops and under task manager I don't see anything running either and no HDD usage, thats why it's kinda weird and suspicious for me. Sometimes it just stops, and it shows more activity just after display is turned off. Might it be some kind of scheduled "hidden" activity I'm not aware about or what?
    It's definitely not some kind of disk defrag or sth.
    I might do Avast scan and see if some virus shows up, but I haven't downloaded anything suspicious.

    Maybe you guys know more about this.

    This sounds like your schedulred maintenence which will happen either a defined time (normally 3 am) or if this time is not free at the next time your PC is not busy.

    Don't worry about it.

    The search indexer will also run when the PC is idle.

    Yeah, I thought so. It had to be some scheduled operation.
