Macbook noise problem

[Rap Sizzle]

My first generation unibody Macbook hasn't had any problems to this date but now it's constantly making that mechanical loading-like noise which is usually heard when the Macbook is switched on (the noise before the start up sound) or when the lid is opened to wake up the computer. Is there a fix to this?

I believe that would be the Superdrive making that noise.

There was a firmware update in the past that is supposed to address that issue.

Possibly this one:
MacBook EFI Update 1.4

But just run software update and if its needed, will be listed.
