HDD only recognized after reset

So it might be an issue with these WD drives?

No, I think not. I have (had) the same issue rarely with a Maxtor Basics and a WD Elements Drive. Unplug and plug in again was the solution here too. But I’ve made the observation that sometimes after a few minutes (~5 min or more) the drive was recognized again without intervention of me. Very strange.
