It's Ticking—
#1
My MacBook Pro, that is. Not all the time, but now and then, about two ticks per second. New this week.

Any idea what this is? Fan? HD about to die? Nothing at all ("they all do it" )?

Hard drive. Should never happen. Typically you'd be having serious performance problems already, once you heard it . . .
What's your backup situation?

could be either fan or HD, or even optical if you have media in there... back up everything and run some diagnostic utilities. how old is MBP? any applecare left? can you pinpoint location of sound?

I have a power supply on an iBook that ticks when the iBook is unplugged. Could it be the power supply?

If it's a light ticking sound it could be one of the fans knicking its housing. Esp if you reassembled it yourself recently.

Haven't had the MBP open, except the battery and RAM compartments.

It's under AppleCare through December.

I have a external clone, via SuperDooper! (was using ProSoft Data Backup, but found it somewhat problematic and less than intuitive), and a TimeMachine backup to a 1TB drive.

The ticking is intermittent. Seems OK at the moment. Does not seem connected with fan, or with optical drive. Didn't stop when I disconnected external power. I guess that leaves the HD. :-(

I'm going to borrow my wife's stethoscope and next time see if I can localize it a bit.

If there's a chance you've been wanting to upgrade to a larger internal, now may be the time.
Apple will swap a bad drive once you've removed it. If I were you I'd nuke and pave it before you end up having to give them a dead drive with all your personal info on it to get an exchange.

Hmm. . .

Using stethoscope: hard to tell, but clicking appears loudest on the right side (looking at the screen) and towards the back.

If I lift up the front of the MBP (off the Griffin Elevator stand it's on), the ticking disappears.

Black, you think Apple will swap a drive that is still working? Maybe a call to the local Apple store is in order. . .

This is my main work computer (most of its time spent on my desk), so removing the HD could be a royal pain.

So far, no weird drive behavior.

Depending on the model, sounds like the optical. Is there a disc in it? Is it trying to eject one?

On further reflection, there's almost no chance you would have anything resembling normal performance if that was coming from the hard drive.

I wouldn't take it through airport security until it's fixed.
