Maybe somebody has met this problem.
I have a WD My passport 4 tb formatted to AFS. Product Number WDBBYF10040BBK-0A
It is connected to a Macbook Pro 13" mid 2012 with MacOS Catalina.
Quite often, I will connect the external drive and then the folders will all show up. Then in a few hours, when you look at the folders again, almost all if not all folders disappears. Then when I try to eject it, it will say it needs to be force ejected.
After force ejecting and reconnecting it again, all folders show up again.
Can anyone tell me what is going on?
