I got the Vantec USB adapter and was able to back up data from the windows and linux partitions. Worked well. However, when I tried to do some more with the adapter it did not work and I found the 5V from the power supply was more like 1V and varying. It has a 12V power supply that goes into a small box that outputs 12 and 5V. 12V looks good. I am going to try it with the main PC power supply. Will be exchanging it for another. I can deal with a bad power supply as there are other ways to deal with that even if I have to make one.
