Hi, yes, I am sure, this was not helpfully.
Maybe the problem was (as seen in post #10), that i have not used a Y-cable, which seems to be delivered with the hdd.
I solved the problem with a new usb 3.0-hdd-case, which works fine. I only had to plug the hdd out of the INTENSO-HDD-Case (i had to broke out the plastic) into the new buyed usb 3.0 hdd-case, which I've bought on amazon.
In this constellation I am sure, the problem was not the surface itself; it was the INTENSO-Case. Maybe it had a malfunction... but I'm pretty sure, it only had need more power (with the Y-cable, it gets double-powered). But I haven't found the cable and I was not ready to spend 2 usb-ports for that lazy hdd. With that new hdd-case, the hdd works fine with only 1 usb-port !
