More than disappointed! 2

1st test:
The 220v cord is VERY poor quality: I had trouble connecting to the transformer because the 2 holes are not centered in the plastic. Multi-outlet side, the outlet is not yours as well 2 records are too small and were twisted. I had the impression to find my shaver 1970!
2nd test:
After replacing the USB3 cable, the 2 discs are finally detected by Windows.
But during a simple copy 50GB of data on a disc to another, the transfer stops after 1 minute, 3 LEDs (power supply + presence of 2 discs) remain lit without flashing and the Windows progress bar stop progress. Same thing with another computer.
I was forced to unplug the unit to unlock Windows ...
