Firmware Bug Causes Noise
Some models make a loud and strange noise for nothing when you're not accessing the hard drive. The affected models are: AC11200, AC22000, AC22500, AC33200, AC34000, AC34300, and AC35100. This noise is the result, according to WD, of a feature (read: BUG) of the hardware of these hard drives. WD created a utility to upgrade the firmware of these hard drives and after the upgrade they stop making noise. The utility is called wdovrly4.exe
