Disk activity on my iMac seems to be running very high, even wwhen I am not actually doing anything?


Is this an issue as my iMac keeps getting the spinning wheel even when there is little happening.


Any help would be much appreciated.



iMac, Mac OS X (10.7.4)

    Use "Activity Monitor" app from the utilities folder to monitor what causes this. Make sure to not only watch "my processes" but "all processes".


    Common Cause for high Disk I/O is spotlight indexing - in Lion more then in earlier OS. IT helps to exclude filetypes and folders via Spotlights prefpane in system settings.
