Hello, veiled its been a week since I test on several PC and with several hdd. I have a concern on my main PC is THE only or it is not working yet it is neither too old nor too new. I have a asus motherboard standard that has never had worries, the disc shows me an error (bad or N / S HDD) on the display and not even detect hard disk. Good gold began what I worry or just unlucky because the twenty pc I've tested there as mine or its not working, there is for me a real simple problem to navigate in the menu, especially that there are no instructions in the box and that the wheel does not answer forever the way I want, when I want support often it goes down for example. So with these worries I do not feel that the product is its fair value that is not a 'good' housing should be more to my taste or around the 20 as 40.
