Clicking sound??


You know that soft click sound you hear after you shutdown or put the MAC to sleep? Well, after I installed a new hard drive, I noticed I'm hearing that same click even while I'm using the MAC. Is this normal? Is it the MAC just resting while it's idle? Someone please put my mind at ease... Thanks!
The hard drive is probably going to sleep... check "Energy Saver" in the System Preferences for options on hard drive/system sleep, especially "Put the hard disk(s) to sleep when possible".
