Hi Martin,
In the bios you have set USB 3.0 mode to "auto", set it to "off" or something. So first time its a go, second time after spin down its probably reset. Forcing to usb 2.0 mode or even to usb 1.0 mode is always better. I'm not sure if install will negotiate with a drive if it was set at first time right and second time needs again negotiation for what mode, my guess is that it will run down installation procedure and the time of scanning and negotiation with parts is behind. So forcing hardware to work in a OS/2-eCS acceptable mode is always better.
