I have 2x WD 500GB Green WD5000AZRX in different machines i have recently built.
About every 20-30 seconds i can hear a click coming from the drive, even when the machine has been sat idle for for long periods of time.
Naturally im wondering if the drives are failing, however any test run on it say both drives are fine. Could it be the heads parking? I cant imagine this would be happening every 20-30 seconds though, especially if the machines are idle.

Not to worry, it is normal. As you suspected it is just the sound of the heads parking, which the green drives do pretty often.
If you find it annoying you can use the WDIDLE utility to increase the amount of time before the drives park and spin down.Go to the full post
