Not sure if this is the right place to ask, but here goes ..
I recently bought 2x WD Red Plus 8TB NAS hard drives, and while unboxing them I noticed that they have bumps on their sides, of varying intensities. Please take a look at the pictures below. Are these bumps normal, or are these hard drives potentially damaged/defective ? I bought two of them from the same retailer at the same time, and they both have them. Both have one side with more bumps than the other side. Note that I have not actually used them so far in any way yet.
