I have a WD MyBook external 4Tb drive. I've had it for a few years and have no issues, however, it wakes up several times while my iMac is sleeping. I can hear noise coming from it.

This doesn't bother me much, but waking up from sleep so many times can't be good for the longevity of the drive. Am I correct? I have installed WD software and set it to go to sleep after 15 mins, but - as I said - it keeps waking up. Also, this happened under Sierra, High Sierra and Mojave, and also happens after a clean install. No special disk apps or anything that could be using the drive (it's just for storage of rarely used files).

Any ideas? Is this normal behaviour?

Thanks.
