The adapter has to be thick pins, therefore a fitting together with the standard HDD counterpart of my PC's impossible! I complained about this error the seller. From that I got via PC then only a form, specifying the return address, and questions about the reason for return and for fault description. Reason for return and description of the fault but I had already communicated !! Nevertheless, I do not free-return has been given by the seller! In response, I discarded the cheap part in electronic waste! And now think of the well-known wisdom: "Who buys cheap, buys twice"!
