I have had a mybook 4TB for at least a year, maybe two years. I use it as a drag-and-drop manual backup for my iMac. I did not install any of the WD software, and I don’t use it as a Time Machine drive.
It works fine, but I’ve noticed in the last several months it makes a lot of noise as if it is searching for something, even when it’s not in use. it’s the same regular noise I hear when I am opening a folder and files. There’s no clicking or odd sounds. It will go like this for maybe 20 minutes then stop for a while then start up again, whether I am at the computer or away from it.
This stops when I unmount (eject) the drive from the desktop.
I am not seeing any problems or failures, but I can’t believe this is good for the drive.
I checked it with Disk Utility which told me there was nothing wrong after some analysis.
Any ideas on what is happening, and what I might do to fix this?
iMac Retina late 2015
OS 10.14 Mojave
WD drive is ExFAT
Thanks in advance for any ideas or suggestions
