Is this a normal boot up sound?

When I boot up my laptop my hard drive (I'm pretty sure it's my hard drive) makes this screeching sound. It also makes the same sound from time to time when I'm using the laptop. Link: https://soundcloud.com/bal0r-1/20140623-120031a
The last 2 sounds are the strange sounds. Are they normal?

No I don't. And I don't think that's the sound you think I'm talking about. I'm talking about that small sound at the end.

are you talking about the part that sounds like something is scratching? right?
