3tb MyBook (Mac) running A LOT

well, after copying all files from disk no.1 to no.3 (1.8T) the brand new my book started to do the same noises as no.1 

keeps on working in iddle. so I formated it with disk utility on my mac and still the same. no changes.

can anyone tell us what to do?

has anyone called technical support  WD phone service?
