I never had the high Kernel & System CPU usage, but I saw this issue on a friend's computer.
The process with PID 4 had a high CPU usage. But that issue solved itself.
However, how is disabling HDD timeout (spin down after ** minutes) meant to solve the CPU usage issue? How is it related?
On a vanilla Gateway PC with 6GB RAM (50%), 500GB available disk space, the HD has started showing a very periodic 100% write usage (~12 sec on, 1 sec off). The Read usage is quite normal. This makes the system extremely slow. Resource Monitor reports many processes with PID 4, but none seem...
