As the tittle says, I have just recently purchased the new iBook G4 12" 1.33 GHz. I didn't really notice this until now, and I just need to make sure it's not my mind that is playing tricks on me. Is it normal for the laptop's HDD to be making noises ( clicking and such) with simple operations such as opening the browser? Sometimes it makes these noises when I'm not even doing anything. My time to return for a brand-new exchange is almost up, so I don't want to stuck with a defective product.
