I use Vista x64 on my core2duo with 4 GB of RAM and more than 300 GB of free space on hard disks. When the computer is idle for a while, tremendeous HDD activity starts. I tried to turn off services that might cause HDD activity (file fetching, security scans etc), but the problem is still there.
I hate it! This kills my drives too soon!
Does anybody know whats going on under Vista, when computer is idle?
The processes that have big IO activity when this happenes are lsass and system. The sound of HDD is like defragmentation is going on, but when checking the defrag, it shows, that previous gefrag was some days ago, and next is sceduled to be run after 4 days.
