Grinding drive noise

Hi there,

I’ve just purchased a My Cloud EX2 Ultra. One thing that has concerned me is the amount of grinding (one or both) the drives are making. Its that heavy dull grinding.

Understandably drives do make noises, but this is sounding like some of my aged (3 years plus) external drives. Diagnostics are saying the drive is in perfect working order but for a pricey unit (16TB version) it’s not sounding the most smoothest.

WD link says it COULD be a cause for concern, but I suppose its what the definition of grinding is. Its enough for me to post here. Has anyone experienced this?

I’d recommend contacting WD Support about this. You can do so over the phone or via E-mail.
