HS power cable, hard drive runs but obligation to return the set.

I put 2 stars only because the drive was not working. But as I took care to do testing, it turned out that it was the power cable at issue because I put a personal cable and hard drive worked perfectly. Thus I noted that the hard drive had a number of files already probably backup software but I do not know of this and actually the size of the hard disk that you can actually disposed is 2.7 to not three. After information taken from the Amazon customer service, I was forced to return all because they do not make the "spare part" especially as in this case, they are an intermediary, the seller being ABAPRIX. I expect the repayment to buy another identical hoping I'd have more luck this time as the reviews were pretty good on this unit.
