Yes, I still have the old PSU lying around. A co-worker, to whom I explained my problem, asked me whether I had properly grounded my drives. In fact I had not: The drives resided in a vibration-absorbing frame through which their exterior had no electrical contact with the grounded case. Since I grounded the drives two days ago, I got no new errors. So maybe my problem is solved. If not, I will happily try out your suggestion. Would you be so kind to explain in a few words, what connecting one drive to a second (supposedly good) PSU will show? (Is this still on-topic on this list?)
