I just bought a WD 10TB My Book Desktop External Hard Drive, USB 3.0 (WDBBGB0100HBK-NESN) and it is connected to my Macbook 2019 13" via Caldigit TS3+ thunderbolt hub.

When I eject the drive from Macbook or even have Macbook turned off the WD hard drive continues to periodically(every 2 seconds) make fai t noise that sounds like head seeking noise as well as some other electric noises. It stops if I unplug the usb cable from the drive.

I have many WD external My Book drives (8tb and under) and they never make this noise when ejected or when laptop off.

Is this normal behavior or should I return it within 30 day window? Could it be a function of the helium drive design?

I am on OSX 10.14.6
