Hard disk always running

Hello. A week ago my hard disk has begin to always running. So i try to find a solution. First i've formatted and for two days always is ok. but now hd has begin to run again.. I have stopped windows search service and it's seem to go well. is there a solution that not involved stopping windows search service? my pc seems slow and sometimes i have to reset. i've checked for virus and there are no weird process in background. i think that perhaps is ccleaner with ccenhancer: perhaps it have cleaned some cache and pc is now rebuilding this cache.

Go into to command prompt type in
CHKDSK /f and hit enter to check your disk and fix any errors.

i've already done. no error.

Download procmon from Microsoft technet once downloaded, Monitor HDD Activity and use the summary option on tools tab
