Not at the level expected 1

Bought to replace the previous dock "All in one" who did not recognize my records, I had read that it was more efficient. On paper, in fact, he did the same and better, thanks to 1 USB 3. Unfortunately, on my Windows 7 x64 environment, none of that! It does not recognize more ... Is it the fact that I only use old disks that have crashed at one time or another one? Even the newest, but it is "dynamic", is not recognized although healthy! I also returns. Thank you Amazon for this procedure simple and effective return.
