Whenever I shutdown my PC the last thing I hear is the HDD come to a loud beep noise for a second. The noise is in this video at 1:13... he says its the HDD emergency shutdown.

How can I fix this problem? I ran some sort of HDD check and it said it was ok. The drive I have is the Western Digital, Blue, 500GB, 7200rpm.

Here is someone with a different HDD model number but the exact same problem...

Try this:
Single beep actually represents memory problem.
Remove each of the memory sticks you have in the computer and then placing them back into the computer also try to Swap memory location.. Hope problem is resolved.
