i do have a problem with my WD MyBook World Edition 1,5TB. When the HDD is in idle mode then the HDD is very noisy. When i access to the MyBook the HDD isnt noisy but when i am done with copying things etc. and the HDD is going to idle then its so noisy and annoying. Does anybody know what i can do? I cant let the MyBook powered on when i am finished with copying files because of that problem.
