Try a PRAM reset:
- Shut down your Mac.
- Locate the following keys on the keyboard: Command (⌘), Option, P, and R. You will need to hold these keys down simultaneously in step 4.
- Turn on the computer.
- Press and hold the Command-Option-P-R keys before the gray screen appears.
- Hold the keys down until the computer restarts and you hear the startup sound for the second time.
- Release the keys.

Thanks, The PRAM reset seems to have calmed down the HDD a lot, and my MacBook feels faster, but it still won't sleep! I did notice however that it sleeps with the charger unplugged. Thoughts?

Go to: System Preferences / Energy Saver. Click the Power Adapter tab. Select Put hard disks to sleep when possible.

Yeah, just checked and that box was already ticked. Do you reckon it matters if the HDD is running all the time?

See this old discussion:
The consensus seems to be to not allow sleep.
Assume this is not a SSD - with an SSD no sleep is definitely recommended.
