Portable HD, My Passport SE 1TB - vibrate issue

Just purchased the 1TB My Passort SE yesterday, I installed it and registered with you today.


I also own two other Hard drive, both Toshiba, 500GB.

While all three HDs sit side-by-side, no files being accessed from or to the HDs, WD My Passport SE 1TB external actually vibrates while the Toshibas are practically quiet.

Why does this happen? isolated issue? should I return this product?

This won’t answer your question, but I also found that my 1 Tb Passport SE vibrates when at speed; it’s noticeable if one puts one’s finger lightly on the housing. When it’s in sleep mode no vibration is noticeable - ed
