Hi!

Is there some kind of brake method why the drives are making this kind of sound when stopping?
They are brand new. Never heard this kind of sound.

Hi,
My 6tb red efax started to do this sound at the end of the power off. My drive is an rma changed hdd. Earlyer hdd at the first start went wrong. It was like a big truck after first power on.
